description

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-bufferamplifier, adigital-controlleddiode-bridgeswitch, andahigh-impedanceoutputbufferamplifier. The

electronic switch is controlled by an LS-TTL-compatible logic input.

high-impedance circuits. During storage or handling, the device leads should be shorted together or the device should be placed in

conductive foam. In a circuit, unused inputs should always be connected to an appropriate logic voltage level, preferably either V
