1. General description
The ADC0801S040 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 V 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/Transistor-Transistor Logic (TTL) compatible. A sleep mode allows
reduction of the device power consumption to 4 mW.
