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.ApplicationsADC BuffersAutomotive Power TrainDAC Output AmplifiersDigital ScalesLow-Noise Microphone/PreamplifiersMedical InstrumentationStrain Gauges/Sensor AmplifiersTransimpedance Amplifiers

The MAX40079/MAX40087/MAX40077/MAX40089/MAX40078 are wide band, low-noise, low-input bias current operational amplifiers that offer rail-to-rail outputs and single-supply operation from 2.7V to 5.5V. These low-noise amps draw 2.2mA of quiescent supply current per amplifier. This family of amplifiers offers ultra-low distortion (0.0002% THD+N), as well as low input voltage-noise density (4.2nV/√Hz) and low input current-noise density (0.5fA/√Hz). The low input bias current of 0.3pA (typ) and low noise (4.5nV/√Hz), together with the wide bandwidth, provides excellent performance for trans-impedance (TIA) and imaging applications.These amplifiers have outputs which swing rail-to-rail and their input common-mode voltage range includes ground. The MAX40079/MAX40077/MAX40078 are single/dual/quad respectively in unity-gain stable with a bandwidth of 10MHz. The MAX40087/MAX40089 are single/dual respectively with gain ≥ 5 stable and bandwidth of 42MHz. They operate over the full -40°C to +125°C temperature range.Single channel op amps are available in 6-bump wafer-level package (WLP) and SOT23 6-pin packages. The dual channel op amps are available in 8-bump WLP and µMAX-8 packages. The quad channel option is available in 14-TSSOP package.ApplicationsADC BuffersDAC Output AmplifiersDigital ScalesLow-Noise Microphone/PreamplifiersMedical InstrumentationpH Probes and Reference ElectrodesStrain Gauges/Sensor AmplifiersTransimpedance Amplifiers
