ADC08031/ADC08032/ADC08034/ADC08038

8-Bit High-Speed Serial I/O A/D Converters with

Multiplexer Options, Voltage Reference, and Track/Hold

Function

n Test systems

n Embedded diagnostics

General Description

The ADC08031/ADC08032/ADC08034/ADC08038 are 8-bit

successive approximation A/D converters with serial I/O and

configurable input multiplexers with up to 8 channels. The

serial I/O is configured to comply with the NSC MICROW-

Features

n Serial digital data link requires few I/O pins

n Analog input track/hold function

n 2-, 4-, or 8-channel input multiplexer options with

address logic

™

IRE serial data exchange standard for easy interface to the

™

COPS family of controllers, and can easily interface with

standard shift registers or microprocessors.

The ADC08034 and ADC08038 provide a 2.6V band-gap de-

rived reference. For devices offering guaranteed voltage ref-

erence performance over temperature see ADC08131,

ADC08134 and ADC08138.

n 0V to 5V analog input range with single 5V power

supply

n No zero or full scale adjustment required

n TTL/CMOS input/output compatible

n On chip 2.6V band-gap reference

n 0.3" standard width 8-, 14-, or 20-pin DIP package

n 14-, 20-pin small-outline packages

A track/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

combinations

single-ended,

differential,

pseudo-differential modes. In addition, input voltage spans

as small as 1V can be accommodated.

Key Specifications

n Resolution: 8 bits

n Conversion time (f_C= 1 MHz): 8µs (max)

n Power dissipation: 20mW (max)

Applications

n Digitizing automotive sensors

n Process control monitoring

n Remote sensing in noisy environments

n Instrumentation

n Single supply: 5V_DC( 5%)

⁄2 LSB and 1LSB

n Total unadjusted error:

n No missing codes over temperature

Ordering Information

Industrial (−40˚C ≤ T_A≤ +85˚C)
