MAX4489

SOT23封装，低噪声，低失真，宽波段，轨至轨运算放大器 SOT23, Low-Noise, Low-Distortion, Wide-Band, Rail-to-Rail Op Amps

Description

The MAX4475-MAX4478/MAX4488/ wideband, low-noise, low-distortion operational amplifiers offer rail-to-rail outputs and single-supply operation down to 2.7V. They draw 2.2mA of quiescent supply current per amplifier while featuring ultra-low distortion 0.0002% THD+N, as well as low input voltage-noise density 4.5nV/ and low input current-noise density 0.5fA/. These features make the devices an ideal choice for applications that require low distortion and/or low noise.

For power conservation, the MAX4475/MAX4488 offer a low-power shutdown mode that reduces supply current to 0.01µA and places the amplifiers" outputs into a high-impedance state. These amplifiers have outputs which swing rail-to-rail and their input common-mode voltage range includes ground. The MAX4475-MAX4478 are unity-gain stable with a gain-bandwidth product of 10MHz. The MAX4488/4489 are internally compensated for gains of +5V/V or greater with a gain-bandwidth product of 42MHz. The single MAX4475/MAX4476/MAX4488 are available in space-saving, 6-pin SOT23 and TDFN packages.
