High-Precision, Low-Voltage,
Micropower Op Amp
General Description
The MAX480 is a precision micropower operational ampli-
fier 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.
Both the input and output voltage ranges include the neg-
ative supply rail, allowing maximum signal range capabili-
ty 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 con-
sumes 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.
The MAX480 is available in 8-pin DIP and SO packages in
commercial, extended, and military temperature ranges.
