GENERAL DESCRIPTION
The OP-421quadlow-power operational amplifier isa single-
chip quad patterned after the OP-21 single operational
amplifier. The PNP input stage allows the input common-
mode voltage to include V-. Featuring a low power-supply
current (150PA/section typical at 5V), the OP-421 offers a
unique solution for designs requiring a combination of high
function density, wide bandwidth, and low-power operation.
Applications forthe OP-421 include low-power active filters,
battery-operated remote Iinefilters, and signal precondition-
ing amplifiers. In addition, the ever-present problem of
crossover distortion in low-power devices is eliminated by a
unique double-buttered output section.

Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not
