OPA615ID Datasheet PDF - TI

The OPA615ID 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. The device features a wideband operational transconductance amplifier (OTA) with a high-impedance cascade current source output and fast and precise sampling comparator that together set a new standard for high-speed applications. Both the OTA and the sampling comparator can be used as stand-alone circuits or combined to form a more complex signal processing stage. The self-biased, bipolar OTA can be viewed as an ideal voltage-controlled current source and is optimized for low input bias current. The sampling comparator has two identical high-impedance inputs and a current source output optimized for low output bias current.
