300MHz High-Speed Op Amp
_______________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 50Ω or 75Ω
loads. Available in DIP, SO, space-saving µMAX, and
SOT23 packages.
