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

■ Sampling rate up to 40 MHz

■ 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

■ Video data digitizing

■ Camera

■ Camcorder

■ Radio communication

■ Car alarm system
