MAX4254ESD

Quad, single-supply operation +2.4V to 5.5V, low-noise, low-distortion, Rail-to-Rail op amp. Gain bandwidth 3MHz, min stable gain 1V/V.e

General Description

The MAX4249–MAX4257 low-noise, low-distortion operational amplifiers offer Rail-to-ail®outputs and single supply operation down to 2.4V. They draw only 400µA of quiescent supply current per amplifier while featuring ultra-low distortion 0.0002% THD, as well as low input voltage noise density 7.9nV/√Hz and low input current noise density 0.5fA/√Hz. These features make the devices an ideal choice for portable/battery-powered applications that require low distortion and/or low noise.
