Product specification

40 Msps, 10-bit analog-to-digital interface

for CCD cameras

TDA8783

APPLICATION INFORMATION

Fig.16 Application diagram.

Depending on the application, the following connections must be made:

(1) The clamp level of the signal input at ADCIN can be tuned from code 00 to code 511 in 0.5 LSB steps of ADC via the serial interface

(clamp ADC activated).

(3) All supply pins must be decoupled with 100 nF capacitors as close as possible to the device.
