DESCRIPTION
The 3584 is a high voltage, high speed hybrid opera-
tional amplifier designed for a wide variety of
programmable power supply and transducer driver
applications.
The 3584 operates over a wide power supply range
(
70V to
150V) and provides outputs up to 15mA.
Laser-trimmed FET input circuitry provides low offset
voltage (3mV max) and low input bias current (20pA
max). Thermal shut-down circuitry protects internal
circuitry from excessive power dissipation.
The 3584 provides a gain-bandwidth product of 20MHz
min (50MHz typical). External frequency compensa-
tion (series R/C) allows the user to optimize the
bandwidth and slew rate for a particular application.
Specified temperature range is 0
C to +70
C. The
3584's hermetic 8-pin TO-3 package is electrically
isolated from all internal circuitry.

APPLICATION INFORMATION
Figure 1 shows the basic connections required to operate the
3584. Bypass capacitors should be connected close to the
device pins. Be sure that these capacitors have an adequate
voltage rating.
Frequency compensation components must be connected to
pin 8 for closed-loop gains of 100 or less. Recommended
values are shown in Figure 1. Some adjustment in these
values may be required depending on exact circuit configu-
ration and load conditions. Be sure the compensation capaci-
tor has a voltage rating equal to or greater than the positive
power supply voltage, V+. Standard 0.25W resistors can be
used for R
C
.
Input offset voltage and drift of the 3584 are laser-trimmed.
Many applications require no external offset trimming.
Figure 1 shows connection of an optional offset trim poten-
tiometer which connects to pins 3 and 4.
FET input circuitry reduces the input bias current of the
3584 to less than 20pA at room temperature. Input bias
current remains nearly constant throughout the full com-
mon-mode range. Input bias current approximately doubles
for each 10
C increase in case temperature above 25
C.
Heat sinking can help minimize this effect by reducing the
case temperature.
Input circuitry of the 3584 is protected with series limiting
resistors and input clamp diodes. The inputs can withstand
the full rated supply voltage of
150V (common-mode or
differential).
THERMAL PROTECTION
The 3584 has internal thermal shut-down circuitry that
activates at a case temperature of approximately 150
C or
higher. As this circuitry is activated, the output current drive
is reduced. As the case temperature returns to less than the
activation temperature, operation will return to normal.
The thermal shut-down circuit will normally protect the
amplifier during a short-circuit to ground. It will not protect
against short-circuit to one of the power supplies. The
typical performance curve "Safe Operating Area" shows that
the large stress occurring during this high voltage condition
may cause damage if it exceeds 5ms duration. The thermal
protection circuitry will not activate fast enough to protect
the device from short-circuits to one of the power supplies.
The package case of the 3584 is electrically isolated from all
circuitry. No special insulating hardware is required. Al-
though not absolutely required, it is recommended that the
case be connected to ground.
