Maxim MAX477MJA, MAX477ESA, MAX477EPA, MAX477EUK-T, MAX477EUA Datasheet

_______________General Description

The MAX477 is a ±5V wide-bandwidth, fast-settling,
unity-gain-stable op amp featuring low noise, low differ­ential gain and phase errors, high slew rate, high preci­sion, and high output current. The MAX477’s archi­tecture 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 feed­back architectures, the MAX477 has a unique input
stage that combines the benefits of the voltage-feed­back design (flexibility in choice of feedback resistor,
two high-impedance inputs) with those of the current­feedback design (high slew rate and full-power band­width). 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 50Ω or 75Ω
loads. Available in DIP, SO, space-saving µMAX, and
SOT23 packages.

Note 1: Specifications for the MAX477EUK (SOT23 package) are 100% tested at T

A

= +25°C, and guaranteed by design over

temperature.

Note 2: Maximum AC specifications are guaranteed by sample test on the MAX477ESA only.
Note 3: Tested with a 3.58MHz video test signal with an amplitude of 40IRE superimposed on a linear ramp (0 to 100IRE). An IRE is

a unit of video-signal amplitude developed by the Institute of Radio Engineers. 140IRE = 1V.
