UCSP, Single-Supply, Low-Noise,
Low-Distortion, Rail-to-Rail Op Amps EVALUATION KIT AVAILABLE
General DescriptionThe MAX4249–MAX4257 low-noise, low-distortion oper-
ational amplifiers offer rail-to-rail outputs and single-
supply operation down to 2.4V. They draw 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.
For additional power conservation, the MAX4249/
MAX4251/MAX4253/MAX4256 offer a low-power shut-
down mode that reduces supply current to 0.5µA and
puts the amplifiers’ outputs into a high-impedance
state. The MAX4249-MAX4257’s outputs swing rail-to-
rail and their input common-mode voltage range
includes ground. The MAX4250–MAX4254 are unity-
gain stable with a gain-bandwidth product of 3MHz.
The MAX4249/MAX4255/MAX4256/MAX4257 are inter-
nally compensated for gains of 10V/V or greater with a
gain-bandwidth product of 22MHz. The single MAX4250/
MAX4255 are available in space-saving 5-pin SOT23
packages. The MAX4252 is available in an 8-bump chip-
scale package (UCSP™) and the MAX4253 is available in
a 10-bump UCSP. The MAX4250AAUK comes in a 5-pin
SOT23 package and is specified for operation over the
automotive (-40°C to +125°C) temperature range.
