19-0127; Rev. 1; 11/98 17µA Max, Dual/Quad, Single-Supply, Precision Op Amps _______________General Description The MAX478 and MAX479 are dual and quad micropower, precision op amps available in 8-pin and 14-pin DIP and small-outline packages, respectively. Both devices feature an extremely low, 17µA max supply current per op amp, 70µV max offset voltage, 2.2µV/°C max offset voltage drift (0.5µV/°C typ), and 250pA max input offset current. The MAX478 and MAX479 operate from a single supply. 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 supply operation, with guaranteed specifications at each supply voltage.
