Micropower Op Amp
Features The MAX480 is a precision micropower operational amplifier with flexible power-supply capability. Its guaranteed
140µV maximum offset voltage (25µV typ) is the lowest of
any micropower op amp. Similarly, input bias current,
input offset current, and drift specifications are within tight
limits. ♦ Single-or Dual-Supply Operation: +1.6V to +36V,
±0.8V to ±18V Both the input and output voltage ranges include the negative supply rail, allowing maximum signal range capability in single-supply applications. The MAX480 operates
with either a single supply ranging from +1.6V to +36V or
dual supplies from ±0.8V to ±18V. The MAX480 consumes less than 20µA, allowing operation in excess of
10,000 hours from a 250mA-hr lithium coin cell. Even with
a minimal quiescent current, the amplifier sinks or sources
5mA from its output. ♦ 20μA Max Supply Current ♦ True Single-Supply Operation: Input and Output
Voltage Ranges Include Ground
♦ 2.0μV/°C Max Offset Voltage Drift
♦ 5mA Min Output Drive …
