description
The TLC5733A is a 3-channel 8-bit semiflash analog-to-digital converter (ADC) that operates from a single 5-V
power supply. It converts a wide-band analog signal (such as a video signal) to digital data at sampling rates
up to 20 MSPS minimum. The TLC5733A contains a feed-back type high-precision clamp circuit for each ADC
channel for video (YUV) applications and a clamp pulse generator that detects COMPOSITE SYNC^† pulses
automatically. A clamp pulse can also be supplied externally. The output-data format multiplexer selects a ratio
of Y:U:V of 4:4:4, 4:1:1, or 4:2:2. For RGB applications, the 4:4:4 output format without clamp function can be
used. The TLC5733A is characterized for operation from − 20°C to 75°C.
