The ADC08131/ADC08134/ADC08138 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 MICROWIRE™ serial data exchange standard for easy interface to the COPS™ family of controllers, and can easily interface with standard shift registers or microprocessors.

All three devices provide a 2.5V band-gap derived reference with guaranteed performance over temperature.

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 of single-ended, differential, or pseudo-differential modes. In addition, input voltage spans as small as 1V can be accommodated.

Features

Serial digital data link requires few I/O pins
Analog input track/hold function
4- or 8-channel input multiplexer options with address logic
On-chip 2.5V band-gap reference (±2% over temperature guaranteed)
No zero or full scale adjustment required
TTL/CMOS input/output compatible
0V to 5V analog input range with single 5V power supply

Key Specification

Resolution	8 Bits
Conversion time (f_C = 1 MHz)	8 µs (Max)
Power dissipation	20 mW (Max)
Single supply	5 V_DC (±5%)
Total unadjusted error	±½ LSB and ±1 LSB
Linearity Error (V_REF = 2.5V)	±½ LSB
No missing codes (over temperature)
On-board Reference	+2.5V ±1.5% (Max)

Applications

Digitizing automotive sensors
Process control/monitoring
Remote sensing in noisy environments
Embedded diagnostics
