Product Details
The MAX40075/MAX40088 are wideband, low-noise, low-input bias current operational amplifiers offering rail-to-rail outputs and single-supply operation down to 2.7V. They draw 2.2mA of quiescent supply current per amplifier when enabled and have ultra-low distortion (0.0002% THD+N), as well as low input voltage-noise density (4.2nV/) and low input current-noise density (0.5fA/
). The low input bias current and low noise together with the wide bandwidth suit transimpedance amplifiers and imaging applications.
For power conservation, the MAX40075/MAX40088 offer a low-power shutdown mode that reduces supply current to 0.1µA and places the amplifiers outputs into a high impedance state. These amplifiers have outputs which swing rail-to-rail and their input common-mode voltage range includes ground. The MAX40075 is unity-gain stable with a gain-bandwidth product of 10MHz. The MAX40088 is gain-of-5 stable with a gain-bandwidth product of 42MHz.
