OP AMP 22MHZ 2.1V/US UMAX-8
The 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.
