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 feed-back 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 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.
