MAX923ESA-LF is an analog device produced by Analog Devices Inc. It is an ultra-low-voltage, low-power, single-channel, low-noise, rail-to-rail input/output (RRIO) amplifier. It is designed for high-precision low-level signal conditioning. The device operates from a single 1.8 V to 5.5 V power supply while keeping wide gain bandwidth and low noise levels even at low supply voltages. The device features a low noise floor, high common-mode range, wide signal-level dynamic range, and low distortion levels. It is available in a small, 5-pin SOT-23 package and is fully specified over the -40°C to +85°C temperature range. It is also RoHS compliant and suitable for automotive applications.
