Detailed Description
The MAX4249–MAX4257 single-supply operational
amplifiers feature ultra-low noise and distortion while
consuming very little power. Their low distortion and low
noise make them ideal for use as preamplifiers in wide
dynamic-range applications, such as 16-bit analog-to-
digital converters (see
Typical Operating Circuit). Their
high-input impedance and low noise are also useful for
signal conditioning of high-impedance sources, such
as piezoelectric transducers.
These devices have true rail-to-rail output operation,
drive loads as low as 1k" while maintaining DC accura-
cy, and can drive capacitive loads up to 400pF without
oscillation. The input common-mode voltage range
extends from VDD - 1.1V to 200mV beyond the negative
rail. The push-pull output stage maintains excellent DC
characteristics, while delivering up to ±5mA of current.
The MAX4250–4254 are unity-gain stable, whereas, the
MAX4249/MAX4255/MAX4256/MAX4257 have a higher
slew rate and are stable for gains # 10V/V. The
MAX4249/MAX4251/MAX4253/MAX4256 feature a low-
power shutdown mode, which reduces the supply cur-
rent to 0.5A and disables the outputs.
The MAX4250AAUK is specified for operation over the
automotive (-40°C to +125°C) temperature range.
