TYPICAL CONNECTION AND COMPENSATION
The typical connection diagram (above) shows the AM-1435
in a unity-gain inverting configuration. When used in any
conventional operational-amplifier configuration, the AM-1435
(as a non-inverting amplifier) requires a noise gain of at least
two (noise gain = 1 + R4/R1).
The 2pF compensation capacitor, C1, at pin 3 is required
for stable operation when the noise gain is less than 10.
Compensation for bias current is provided by R2 and its value
is determined by the formula:
The offset adjust potentiometer R3 and the compensation
capacitor C4 are optional. Note, however, that C4 should
be implemented when driving capacitive loads to prevent
oscillation of the output stage.
Operation of the AM-1435 at low impedances requires careful
attention to include the feedback resistor as a part of the total
output load.
