ADCV08832
Low Voltage, 8-Bit Serial I/O CMOS A/D Converter with
Sample/Hold Function
General Description
The ADCV08832 is a low voltage, 8-Bit successive approxi-
mation analog-to-digital converter with a 3-wire serial inter-
face. The serial I/O will interface to microcontrollers, PLD’s,
microprocessors, DSPs or shift registers. The serial I/O is
configured to comply with the NSC MICROWIRE™ serial
data exchange standard.
To minimize total power consumption, the ADCV08832 can
be set to go into low power mode whenever it is not perform-
ing conversions.
A sample/hold function allows the analog voltage at the
positive input to vary during the actual A/D conversion. The
analog inputs can be configured to operate in various com-
binations of single-ended, differential, or pseudo-differential
modes.
Features
n 3-wire serial digital data link requires few I/O pins
n Single supply 2.7V to 5V
n Analog input track/hold function
n Analog input voltage range from GND to V
CC

n TTL/CMOS input/output compatible
n Superior pin compatible replacement for TLV0832 and
ADC0832
Applications
n Digitizing sensors and waveforms
n Process control monitoring
n Remote sensing in noisy environments
n Instrumentation
n Embedded systems
n Low power circuits
Key Specifications
(For 3.3V supply, typical, unless otherwise noted)
n Resolution 8 bits
n Conversion time (f
CLK
= 500 kHz) 16 µs (max)
n Power dissipation 1.7 mW
n Power down mode <0.1 µW
n Total Unadjusted Error ±0.8 LSB
n No missing codes over temperature (−40˚C to +125˚C)
