Low-power voltage-feedback operational amplifier provides rail-to-rail input and output operation for precision signal conditioning and ADC driver applications. The amplifier operates from a 2.7 V to 11 V supply range and consumes about 1.0 mA per amplifier when enabled. Dynamic performance includes 180 MHz small-signal bandwidth, 225 V/µs slew rate, and 47 ns settling time to 0.1% for a 4 V step. Input noise is 3.1 nV/√Hz at 100 kHz with a 29 Hz voltage-noise corner, and the device operates across the −40°C to +125°C industrial temperature range. The single-amplifier version is supplied in 6-lead SC70 and 6-lead SOT-23 packages with a disable function for low-current shutdown.
