General Description
The MAX4475–MAX4478/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) and low input current-noise density
(0.5fA/
√Hz). 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 0.01A 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.
