DESCRIPTION

fier optimized to drive a variety of loads from DC through the

video frequency range. Excellent input accuracy is achieved

with a dual monolithic FET input transistor which is cascoded

by two high voltage transistors to provide outstanding common

mode characteristics. All internal current and voltage levels

are referenced to a zener diode biased on by a current source.

As a result, the PA119 exhibits superior DC and AC stability

over a wide supply and temperature range.

by a complementary power MOS output stage. For optimum

linearity, especially at low levels, the power MOS transistors

are biased in a class A/B mode. Thermal shutoff provides

full protection against overheating and limits the heatsink

requirements to dissipate the internal power losses under

normal operating conditions. A built-in current limit of 0.5A

can be increased with the addition of two external resistors.

Transient inductive load kickback protection is provided by

two internal clamping diodes. External phase compensation

allows the user maximum flexibility in obtaining the optimum

slew rate and gain bandwidth product at all gain settings. A

heatsink of proper rating is recommended.

capacitors, and silicon semiconductor chips to maximize reli-

ability, minimize size, and give top performance. Ultrasonically

bonded aluminum wires provide reliable interconnections at all

operating temperatures. The 8-pin TO-3 package is hermeti-

cally sealed and electrically isolated. The use of compress-

ible thermal washers and/or improper mounting torque will

void the product warranty. Please see “General Operating

Considerations” .

TYPICAL APPLICATION

PA119 and provides a unique interface with a current output

DAC. By using the DAC’s internal 1KΩ feedback resistor,

temperature drift errors are minimized, since the temperature

drift coefficients of the internal current source and the internal

feedback resistor of the DAC are closely matched. Gain of

with the external 500Ω and 110Ω form a “tee network” in the

feedback path around the PA119. This effective resistance

equals 6.5KΩ . Therefore the entire circuit can be modeled

as 6.5KΩ feedback resistor from output to inverting input and

a 5mA current source into the inverting input of the PA119.

Now we see the familiar current to voltage conversion for a

DAC where V
