GENERAL DESCRIPTION
The TDA8790 is an 8-bit universal analog-to-digital
converter (ADC) for video and general purpose
applications. It converts the analog input signal from
2.7 to 5.5 V into 8-bit binary-coded digital words at a
maximum sampling rate of 40 MHz. All digital inputs and
outputs are CMOS/TTL compatible. A sleep mode allows
reduction of the device power consumption down to 4 mW.
