OPA615IDG4

宽带宽，直流恢复电路 Wide-Bandwidth, DC Restoration Circuit

DESCRIPON

The OPA615 is a complete subsystem for very fast and precise DC restoration, offset clamping, and low-frequency hum suppression of wideband amplifiers or buffers. Although it is designed to stabilize the performance of video signals, the circuit can also be used as a sample-and-hold amplifier, high-speed integrator, or peak detector for nanosecond pulses.
