ADCV0831
8 Bit Serial I/O Low Voltage Low Power ADC with
Auto Shutdown in a SOT Package
General Description
The ADCV0831 is a low voltage 8-bit successive approxima-
tion A/D converter with serial I/O. The I/O is a 3-wire serial in-
terface compatible with NSC’s MICROWIRE ™ & Motorola’s
SPI standards. It easily interfaces with standard shift regis-
ters or microprocessors.
Low voltage and auto shutdown features make the
ADCV0831 ideal for portable battery operated electronic de-
vices. The main benefits are most apparent in small portable
electronic devices. The tiny A/D converter can be placed
anywhere on the board.
