GENERAL DESCRIPTION
The ADA4806-1 is a high speed, voltage feedback, rail-to-rail output, single operational amplifier with three power modes: full power mode, sleep mode, and shutdown mode. In full power mode, this amplifier provides a wide bandwidth of 105 MHz at a gain of +1, a fast slew rate 160 V/μs, and excellent dc precision with a low input offset voltage of 125 μV (maximum) and an input offset voltage drift of 1.5 μV/°C (maximum), while consuming only 500 μA of quiescent current. Despite being a low power amplifier, the ADA4806-1 provides excellent overall performance, making it ideal for low pow...
