MAX480中文资料高精度、低电压、微功耗运算放大器数据手册ADI规格书

描述 Description

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.
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.
The MAX480 is available in 8-pin DIP and SO packages in commercial, extended, and military temperature ranges.
