OPA615IDGST General Description

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. The device features a wideband Operational Transconductance Amplifier (OTA) with a high-impedance cascode 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 and offset voltage; it can be controlled by a TTL-compatible switching stage within a few nanoseconds. The transconductance of the OTA and sampling comparator can be adjusted by an external resistor, allowing bandwidth, quiescent current, and gain trade-offs to be optimized.

The OPA615 is available in both an SO-14 surface-mount and an MSOP-10 package.
