Zero-drift operational amplifier provides rail-to-rail input and output operation from a 2.7 V to 5 V single supply. The single-amplifier device has very low offset voltage, low offset drift, and low low-frequency noise for precision signal conditioning. It supports a 2.5 MHz gain bandwidth product and 1 V/µs slew rate while drawing microampere-level supply current. The operating temperature range extends from -40 °C to +125 °C, with package options in small surface-mount formats.
