__________Typical Operating Circuit

_______________General Description
The MAX478 and MAX479 are dual and quad micro-
power, precision op amps available in 8-pin and 14-pin
DIP and small-outline packages, respectively. Both
devices feature an extremely low, 17 A max supply
current per op amp, 70V max offset voltage, 2.2V/°C
max offset voltage drift (0.5V/°C typ), and 250pA max
input offset current.
The MAX478 and MAX479 operate from a single sup-
ply. The input voltage range includes ground, and the
output swings to within a few millivolts of ground, which
eliminates pull-down resistors and saves power.
Both devices are optimized for single 3V and 5V sup-
ply operation, with guaranteed specifications at each
supply voltage. Specifications for ±15V operation are
also provided.
