FEATURES
The SP9504 is a lowpower replacement for the
popular SP9345, Quad 12-Bit Digital-to-Analog
Converter. This Quad, Voltage Output, 12-Bit Digi-
tal-to-Analog Converter features
4.5V output swings
when using
5 volt supplies. The input coding format
used is standard offset binary, Table 1.
The converter utilizes double-buffering on each of the
12 parallel digital inputs, for easy microprocessor
interface. Each 12-bit DAC is independently addres-
sable and all DAC
S
may be simultaneously updated
using a single XFER command. The output settling-
time is specified at 4
s to full 12bit accuracy when
driving a 5Kohm, 50pF load combination. The
SP9504, Quad 12-Bit Digital-to-Analog Converter is
ideally suited for applications such as ATE, process
controllers, robotics, and instrumentation. The SP9504
is available in 28pin plastic DIP or SOIC packages,
specified over the commercial (0
C to +70
C)
temperature range.
THEORY OF OPERATION
The SP9504 consists of five main functional blocks
-- input data multiplexer, data registers, control logic,
four 12-bit D/A converters, and four bipolar output
voltage amplifiers. The input data multiplexer is
designed to interface to either 12- or 8-bit micropro-
cessor data busses. The input data format is controlled
by the B1/B2 signal -- a logic "1" selects the 12-bit
mode, while a logic "0" selects the 8-bit mode. In the
12-bit mode the data is transferred to the input registers
without changes in its format. In the 8-bit mode, the
four least significant bits (LSBs) are connected to the
four most significant bits (MSBs), allowing an 8-bit
MSB-justified interface. All data inputs are enabled
using the CS signal in both modes. The digital inputs
are designed to be both TTL and 5V CMOS compat-
ible.
In order to reduce the DAC full scale output sensitivity
to the large weighting of the MSB's found in conven-
tional R-2R resistor ladders, the 3 MSB's are decoded
into 8 equally weighted levels. This reduces the
contribution of each bit by a factor of 4, thus, reducing
the output sensitivity to mismatches in resistors and
switches by the same amount. Linearity errors and
stability are both improved for the same reasons.
Each D/A converter is separated from the data bus by
two registers, each consisting of level-triggered latches,
Figure 1. The first register (input register) is 12-bits
wide. The input register is selected by the address
input A
0
and A
1
, and is enabled by the CS and WR1
signals. In the 8-bit mode, the enable signal to the 8
MSB's is disabled by a logic low on B1/B2 to allow
the 4 LSB's to be updated. The second register (DAC
register), accepts the decoded 3 MSB's plus the 9
LSB's. The four DAC registers are updated simulta-
neously for all DAC's using the XFER and WR2
signals. Using the CLR and WR2 signals or the
power-on-reset, (enabled when the power is switched
on) the DAC registers are set to 1000 0000 0000 and
the DAC outputs will settle to 0V.
Using the control logic inputs, the user has full control
of address decoding, chip enable, data transfer and
clearing of the DAC's. The control logic inputs are
level triggered, and like the data inputs, are TTL and
CMOS compatible. The truth table (Table 2) shows
the appropriate functions associated with the states of
the control logic inputs.
The DACs themselves are implemented with a preci-
sion thinfilm resistor network and CMOS transmis-
sion gate switches. Each D/A converter is used to
convert the 12bit input from its DAC register to a
precision voltage.
The bipolar voltage output of the SP9504 is created
on-chip from the DAC Voltage Output (V
DAC
) by
using an operational amplifier and two feedback
resistors connected as shown in Figure 2. This
configuration produces a +4.5V bipolar output range
with standard offset binary coding.

To load a 12-bit word to the input register of
each DAC, using an 8-bit data bus, the sequence
is as follows:
1) Set XFER=1, B1/B2=1, CLR=1, WR1=1,
WR2=1, CS=1.
2) Set D11 through D4 to the 8 MSB's of the
desired digital input code.
3) Load the 8 MSB's of the digital word to
the selected input register by cycling WR1
and CS through the "1" -- "0" -- "1"
sequence.
4) Reset B1/B2 from "1" ---- "0"
5) Set D11 (MSB) through D8 to the 4 LSB's
of the digital input code.
6) Load the 4 LSB's by cycling WR1 and CS
through the "1" -- "0" -- "1" sequence.

bringing WR1 low will transfer the data to the
addressed DAC. The user should be sure to
bring WR1 high again so that the next selected
DAC will not be overwritten by the last digital
code. This mode of operation may be useful in
applications where preloading of the input
registers is not necessary Figure 3a.
A fully transparent mode is realized by tying
WR1, CS, WR2, and XFER all low. In this
mode, anything that is written on the12-bit data
bus will be passed directly to the selected DAC.
Since both latches are not being used, the previ-
ous digital word will be overwritten by the new
data as soon as the address changes. This may be
useful should the user want to calibrate a circuit,
by taking full scale or zero scale readings for all
four DAC's, Figure 3b.
ZEROING DAC OUTPUTS
While keeping XFER pin high, the DAC outputs
can be set to zero volts two different ways. The
first involves the CLR and WR2 pins. In normal
operation, the CLR pin is tied high, thus, dis-
abling the clear function. By cycling WR2 and
CLR through "1" --"0" --"1" sequence, a digi-
tal code of 1000 0000 0000 is written to all four
DAC registers, producing a half scale output or
zero volts. The second utilizes the built in power-
TRANSFERRING DATA
To transfer the four 12-bit words in the four
input registers to the four DAC registers:
1) Set CLR=1, CS=1, WR1=1.
2) Cycle WR2 and XFER through the "1"
-- "0" -- "1" sequence.
To set the outputs of the four DAC's to 0V, cycle
WR2 and CLR through the "1" -- "0" -- "1"
sequence, while keeping XFER=1.
ONE LATCH, OR NO LATCHES
The latches that form the registers can be used in
a "semi-" transparent mode, and a "fully-"
transparent mode. In order to use the SP9504 in
either mode the user must be interfaced to a
12-bit bus only (B1=1).
The semitransparent mode is set up such that
the second set of latches is transparent and the
first set is used to latch the incoming data. Data
is latched into the first set rather than the second
set, in order to minimize glitch energy induced
from the data formatting. In this mode, XFER,
WR2 and CS are tied low, and WR1 is used to
strobe the data to the addressed DAC. Each
DAC is addressed using the address lines A
0
and
A
1
. After the appropriate DAC has been selected
and the data is settled at the digital inputs,

on-reset. Using this feature, the SP9504 can be
configured such that during power-up, the
second register will be digitally "zeroed",
producing a zero volt output at each of the four
DAC outputs. This is achieved by powering the
unit up with XFER in a high state. Thus, with no
external circuitry, the SP9504 can be powered
up with the analog outputs at a known, zero volt
output level.
TEMPORARILY FORCING
ALL DAC OUTPUTS TO 0V
Set
WR1=1, CS=1, WR2=0, XFER=0. The DAC
registers can be temporarily forced to 1000 0000
0000 by bringing the CLR pin low. This will
force the DAC outputs to 0V, while the CLR pin
remains low. When the CLR pin is brought back
high, the digital code at the DAC registers will
again appear at the DAC's digital inputs, and the
analog outputs will return to their previous values.
