MAX4489

The MAX4475MAX4478/MAX4488/MAX4489 wide-band, 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/Hz</a>) and low input current-noise density (0.5fA/Hz</a>). 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 MAX4475MAX4478 are unity-gain stable with a gain-bandwidth product of 10MHz. The MAX4488/MAX4489 are internally compen-sated for gains of +5V/V or greater with a gain-band-width product of 42MHz. The single MAX4475/ MAX4476/MAX4488 are available in space-saving, 6-pin SOT23 packages.
