MAX4253EUB Datasheet PDF - Maxim Integrated

●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.
