Not Recommended for New Designs
This product was manufactured for Maxim by an outside wafer foundry
using a process that is no longer available. It is not recommended for
new designs. The data sheet remains available for existing users.
A Maxim replacement or an industry second-source may be available.
Please see the QuickView data sheet for this part or contact technical
support for assistance.

17µA Max, Dual/Quad, Single-Supply,
Precision Op Amps
___________________________Features
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, 17 µA 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.
♦ 17µA Max Supply Current (MAX478A/MAX479A)
♦ 70µV Max Offset Voltage (MAX478A)
♦ Single-Supply Operation:
Input Voltage Range Includes Ground
Output Swings to Ground While Sinking Current
No Pull-Down Resistors Required
♦ Dual Op Amp in 8-Pin DIP/SO Package (MAX478)
Quad Op Amp in 14-Pin DIP/SO Package (MAX479)
♦ 250pA Max Input Offset Current
(MAX478A/MAX479A)
♦ 0.5µV/°C Offset-Voltage Drift
♦ Output Sources and Sinks 5mA Load 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. Specifications for ±15V operation are
also provided.

Guaranteed by design.
Power-supply rejection ratio is measured at the minimum supply voltage. The op amps actually work at 1.7V supply, but
with additional input offset-voltage skew.
