The TL1591 is a monolithic integrated sample-and-hold circuit that uses the BiFET process with Schottky-barrier diodes and is designed for use with CCD area imagers. This device consists of an ultra-fast input-buffer amplifier, a digital-controlled diode-bridge switch, and a high-impedance output buffer amplifier. The electronic switch is controlled by an LS-TTL-compatible logic input.
