Analog Devices / Maxim Integrated MAX40088 Low Bias Op-Amps

Analog Devices MAX40088 Low Bias Op-Amps are wideband, low-noise, low-input bias current operational amplifiers offering rail-to-rail outputs and single-supply operation down to 2.7V. When enabled, the Analog Devices MAX40088 draws 2.2mA of quiescent supply current per amplifier. 

The amplifiers feature ultralow distortion (0.0002% THD+N), low input voltage-noise density (4.2nV/√Hz) and low input current-noise density (0.5fA/√Hz). The low input bias current, low noise, and wide bandwidth suit trans-impedance amplifiers and imaging applications.
