_______________General Desc ription
The MAX476 is a 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 device architecture uses a
standard voltage-feedback topology that can be con-
figured into any desired gain setting, as with other gen-
eral-purpose op amps.
Unlike high-speed amplifiers using current-mode feed-
back architectures, the MAX476 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. 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 MAX476 is ideally suited for driving 50
or 75
loads. In addition, the device incorporates a high-
speed shutdown mode to disable the output in multi-
plexed applications and to conserve power. Packages
include 8-pin DIP, SO, and μMAX.
