Product Overview
The AT8541 is a zero-drift, low-power CMOS operational amplifier employing auto-calibration to achieve ±7µV typical input offset and 0.08µV/°C offset drift. It operates from a supply as low as 2V while drawing only 40µA per amplifier.
The AT8541 features rail-to-rail input and output with 0.9µVP-P low-frequency noise, making it well suited for precision current sensing, thermocouple amplification, battery-powered instruments, and medical instrumentation.
