GENERAL DESCRIPTION
The TDA8786; TDA8786A is a 10-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, AGC, a soft clipper circuit and a low power 10-bit Analog-to-Digital Converter (ADC) together with its reference voltage regulator.
FEATURES
• Correlated Double Sampling (CDS), AGC, soft clipper, pre-blanking, 10-bit ADC and reference regulator included
• Fully programmable via a 3-wire serial interface
• Sampling frequency up to 18 MHz
• AGC gain from 3.5 to 33.5 dB (in 0.1 dB steps)
• Programmable soft clipper for white compression (starting at 40% of the input signal)
• Standby mode available for each block for power saving applications (19 mW)
• 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 475 mW (typ.)
• 5 V operation and 2.5 to 5 V operation for the digital outputs
• CDS control pulse: TDA8786 = HIGH; TDA8786A = LOW
• TTL compatible inputs, TTL and CMOS compatible outputs.
APPLICATIONS
• CCD camera systems.
