Maxim Integrated introduced new 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.
