Its guaranteed ±0.8V to ±18V 140µV maximum offset voltage (25µV typ) is the lowest of ♦ True Single-Supply Operation: Input and Output any micropower op amp. Similarly, input bias current, Voltage Ranges Include Ground input offset current, and drift specifications are within tight limits. ♦ 2.0μV/°C Max Offset Voltage Drift Both the input and output voltage ranges include the neg- ♦ 20μA Max Supply Current ative supply rail, allowing maximum signal range capabili- ♦ 5mA Min Output Drive ty in single-supply applications. The MAX480 operates with either a single supply ranging from +1.6V to +36V or ♦ 140μV Max Input Offset Voltage dual supplies from ±0.8V to ±18V. The MAX480 con- ♦ 3nA Max Input Bias Current sumes less than 20µA, allowing operation in excess of 10,000 hours from a 250mA-hr lithium coin cell.
