UCSP, Single-Supply, Low-Noise, MAX4249MAX4257 Low-Distortion, Rail-to-Rail Op Amps General Description Features The MAX4249MAX4257 low-noise, low-distortion opera- Available in Space-Saving UCSP, SOT23, and tional amplifiers offer rail-to-rail outputs and single-supply MAX Packages operation down to 2.4V. They draw 400A of quiescent Low Distortion: 0.0002% THD (1k load) supply current per amplifier while featuring ultra-low 400A Quiescent Supply Current per Amplifier distortion (0.0002% THD), as well as low input voltage- Single-Supply Operation from 2.4V to 5.5V noise density (7.9nV/Hz) and low input current-noise Input Common-Mode Voltage Range Includes density (0.5fA/Hz). These features make the devices an Ground ideal choice for portable/battery-powered applications that require low distortion and/or low noise. Outputs Swing Within 8mV of Rails with a 10k Load 3MHz GBW Product, Unity-Gain Stable For additional power conservation, the MAX4249/ MAX4251/MAX4253/MAX4256 offer a low-power shut- (MAX4250MAX4254) 22MHz GBW Product, Stable with A 10V/V down mode that reduces supply current to 0.5A and puts V the amplifiers outputs into a high-impedance state. The (MAX4249/MAX4255/MAX4256/MAX4257) MAX4249-MAX4257s outputs swing rail-to-rail and their Excellent DC Characteristics input common-mode voltage range includes ground. The V = 70V OS MAX4250MAX4254 are unity-gain stable with a gain- I = 1pA BIAS bandwidth product of 3MHz. The MAX4249/MAX4255/ Large-Signal Voltage Gain = 116dB MAX4256/MAX4257 are internally compensated for gains Low-Power Shutdown Mode of 10V/V or greater with a gain-bandwidth product of Reduces Supply Current to 0.5A 22MHz. The single MAX4250/MAX4255 are available in Places Outputs in a High-Impedance State space-saving 5-pin SOT23 packages. The MAX4252 is 400pF Capacitive-Load Handling Capability available in an 8-bump chip-scale package (UCSP) and the MAX4253 is available in a 10-bump UCSP.
