_______________General Description

The MAX477 is a ±5V wide-bandwidth, fast-settling,

unity-gain-stable op amp featuring low noise, low differ-

ential gain and phase errors, high slew rate, high preci-

sion, and high output current. The MAX477’s archi-

tecture uses a standard voltage-feedback topology that

can be configured into any desired gain setting, as with

other general-purpose op amps.

Unlike high-speed amplifiers using current-mode feed-

back architectures, the MAX477 has a unique input

stage that combines the benefits of the voltage-feed-

back design (flexibility in choice of feedback resistor,

two high-impedance inputs) with those of the current-

feedback design (high slew rate and full-power band-

width). It also has the precision of voltage-feedback

amplifiers, characterized by low input-offset voltage

and bias current, low noise, and high common-mode

and power-supply rejection.

The MAX477 is ideally suited for driving 50

Ω or 75Ω

loads. Available in DIP, SO, space-saving µMAX, and

SOT23 packages.
