Product data sheet
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.
2. Features
I 8-bit resolution
I Operation between 2.7 V and 5.5 V
I Sampling rate up to 40 MHz
I DC sampling allowed
I 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)
I CMOS/TTL compatible digital inputs and outputs
I External reference voltage regulator
I Power dissipation only 30 mW (typical value)
I Low analog input capacitance, no buffer amplifier required
I Sleep mode (4 mW)
I No sample-and-hold circuit required
3. Applications
I Video data digitizing
I Camera
I Camcorder
I Radio communication
I Car alarm system
