OPA3691ID Information

General Description

The OPA3691ID is a groundbreaking broadband triple current-feedback op amp that raises the bar for performance. Its remarkably low 5.1mA/ch supply current sets it apart, offering a slew rate and output power typically seen in op amps with much higher supply currents. Thanks to its innovative output stage architecture, the OPA3691ID can deliver a high output current with minimal voltage headroom and crossover distortion, enabling exceptional single-supply operation. With a single +5V supply, this op amp can achieve a 1V to 4V output swing with over 120mA drive current and 150MHz bandwidth, making it an ideal choice for RGB line drivers or single-supply Analog-to-Digital Converter (ADC) input drivers
