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.

Features
■ 8-bit resolution
■ Operation between 2.7 V and 5.5 V

■ High signal-to-noise ratio over a large analog input frequency range (7.3 effective bits at 4.43 MHz full-scale input at fclk = 40 MHz)
■ CMOS/TTL compatible digital inputs and outputs
■ External reference voltage regulator
■ Power dissipation only 30 mW (typical value)
■ Low analog input capacitance, no buffer amplifier required
■ Sleep mode (4 mW)
■ No sample-and-hold circuit required

Applications
