MAX479

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. Specifications for ±15V operation are also provided. ___________________________Features o 17µA Max Supply Current (MAX478A/MAX479A) o 70µV Max Offset Voltage (MAX478A) o Single-Supply Operation: Input Voltage Range Includes Ground Output Swings to Ground While Sinking Current No Pull-Down Resistors Required o Dual Op Amp in 8-Pin DIP/SO Package (MAX478) Quad Op Amp in 14-Pin DIP/SO Package (MAX479) o 250pA Max Input Offset Current (MAX478A/MAX479A) o 0.5µV/°C Offset-Voltage Drift o Output Sources and Sinks 5mA Load Current MAX478/MAX479 ______________Ordering Information PART MAX478ACPA MAX478CPA MAX478CSA MAX478C/D MAX478EPA MAX478ESA MAX479ACPD MAX479CPD MAX479CSD MAX479EPD MAX479ESD TEMP.
