General Description
The CLC5623 has a new output stage that delivers high output
drive current (130mA), but consumes minimal quiescent supply
current (3.0mA/ch) from a single 5V supply. Its current feedback
architecture, fabricated in an advanced complementary bipolar
process, maintains consistent performance over a wide range of
gains and signal levels, and has a linear-phase response up to
one half of the -3dB frequency.
The CLC5623 offers 0.1dB gain flatness to 15MHz and differen-
tial gain and phase errors of 0.06% and 0.06. These features are
ideal for professional and consumer video applications.
The CLC5623 offers superior dynamic performance with a
148MHz small-signal bandwidth, 370V/
s slew rate and 4.4ns
rise/fall times (2V
step
). The combination of low quiescent power,
high output current drive, and high-speed performance make
the CLC5623 well suited for many battery-powered personal
communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
with minimum distortion, makes the CLC5623 ideal for cable
applications.
The CLC5623 will drive a 100
load with only
-78/-94dBc second/third harmonic distortion (A
v
= +2, V
out
=
2V
pp
, f = 1MHz). With a 25
load, and the same conditions, it
produces only -82/-96dBc second/third harmonic distortion.
The CLC5623 can also be used for driving differential-input step-
up transformers for applications such as Asynchronous Digital
Subscriber Lines (ADSL) or High-Bit-Rate Digital Subscriber
Lines (HDSL).
When driving the input of high-resolution A/D converters, the
CLC5623 provides excellent -86/-96dBc second/third harmonic
distortion (A
v
= +2, V
out
= 2V
pp
, f = 1MHz, R
L
= 1k
) and fast
settling time.
