It can be used with one-, two-, and three-channel color and monochrome TI virtual-phase CCDs. Each sample-and-hold channel consists of a differential-input buffer, a digitally controlled switch, and an output buffer that has high impedance. Separate supply and ground pins are provided for the analog and digital sections to ensure optimum isolation. Internal-hold capacitors are included to reduce the external parts count. The differential inputs allow the amplifier return pin of the imager to be connected to CIN of the sample-and-hold circuit to obtain mon-mode rejection for antiblooming clock transients in the CCD. The analog inputs should be capacitively coupled from the CCD outputs to ensure optimum performance. The TL1593C is supplied in a 16-pin plastic package and is characterized for operation from 0°C to 70°C. This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 k V according to MIL-STD-883C, Method 3015; however, precautions should be taken to avoid application of any voltage higher than maximum-rated voltages to these high-impedance circuits.
