Texas Instruments OPA615

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. view all in datasheet
