Texas Instruments ADC08138
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 MICROWIRE serial data exchange standard for easy interface to the COPS™ family of controllers, and can easily interface with standard shift registers or microprocessors. The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes.| Part No. | ADC08138 |

FEATURES
1●23 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 Ensured)
● No Zero or Full Scale Adjustment Required
● TTL/CMOS Input/Output Compatible
● 0V to 5V Analog Input Range with Single 5V Power Supply
APPLICATIONS
● Digitizing Automotive Sensors● Process Control/Monitoring
● Remote Sensing in Noisy Environments
● Embedded Diagnostics
DESCRIPTION
All three devices provide a 2.5V band-gap derived reference with ensured performance over temperature. A track/hold function allows the analog voltage at the positive input to vary during the actual A/D conversion. In addition, input voltage spans as small as 1V can be accommodated.
