描述 Description

GENERAL DESCRIPTION
The TDA8783 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 Analog-to-Digital Converter (ADC) together with its reference voltage regulator.FEATURES
? Correlated Double Sampling (CDS), AGC, 10-bit ADC and reference regulator included, adjustable bandwidth (CDS and AGC)
? Fully programmable via a 3-wire serial interface
? Sampling frequency up to 40 MHz
? AGC gain from 4.5 to 34.5 dB (in 0.1 dB steps)
? CDS programmable bandwidth from 4 to 120 MHz
? AGC programmable bandwidth from 4 to 54 MHz
? Standby mode available for each block for power saving applications 20 mW (typ.)
? 6 dB fixed gain analog output for analog iris control
? 8-bit and 10-bit DAC included for analog settings
? Low power consumption of only 483 mW (typ.)
? 5 V operation and 2.5 to 5.25 V operation for the digital outputs
? TTL compatible inputs, TTL and CMOS compatible outputs.APPLICATIONS
? CCD camera systems.
