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. 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. _______________________Applications Battery- or Solar-Powered Systems: Portable Instrumentation Remote Sensor Amplifier Satellite Circuitry Micropower Sample-and-Hold Thermocouple Amplifier Micropower Filters Single Lithium Cell Powered Systems ___________________________Features ♦ 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 ______________Ordering Information PART TEMP.
