ADC0801S040
Single 8 bits ADC, up to 40 MHz
Rev. 03 — 2 July 2012
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
8-bit resolution
Operation between 2.7 V and 5.5 V
Sampling rate up to 40 MHz
DC sampling allowed
High signal-to-noise ratio over a large analog input frequency range (7.3 effective bits
at 4.43 MHz full-scale input at f
clk
= 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
3. Applications
Video data digitizing
Camera
Camcorder
Radio communication
Car alarm system
