OPERATING CURRENT PROGRAMMABILITY (I
The input bias current, slew rate, gain bandwidth product,
output drive capability and total device power consumption
of both amplifiers can be simultaneously controlled and op-
timized via the two programming pins I
I
The output set current (I
current sourced from pin 1 and establishes the class A
biasing current for the Darlington emitter follower output
stage. Using a single resistor from pin 1 to ground, as shown
in Figure 6, this current is equal to:
The output set current can be adjusted to optimize the
amount of current the output of the amplifier can sink to drive
load capacitance and for loads connected to V
mum output sinking current is approximately 10 times

drive small load impedances.
