描述 Description

GENERAL DESCRIPTION
The TDA8787 is a 10-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, AGC and a low-power 10-bit ADC together with its reference voltage regulator.
AGC gain is controlled via the serial interface. The ADC input clamp level is controlled via the serial
interface.FEATURES
? Correlated Double Sampling (CDS), Automatic Gain Control (AGC), 10-bit Analog-to-Digital Converter (ADC) and reference regulator included
? Fully programmable via a 3-wire serial interface
? Sampling frequency up to 18 MHz
? AGC gain range of 36 dB (in steps of 0.1 dB)
? Low power consumption of only 190 mW (typ.)
? Power consumption in standby mode of 4.5 mW (typ.)
? 3.0 V operation and 2.5 to 3.6 V operation for the digital outputs
? Active control pulses polarity selectable via serial interface
? 8-bit DAC included for analog settings
? TTL compatible inputs, CMOS compatible outputs.
