ADC0834CCWMX

Analog To Digital Converters (ADC) Overview

The ADC0834CCWMX is an 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a software-configurable multiplexer supporting four single-ended or two differential input channels. The device operates on a single 5 VDC supply with a power consumption of 15 mW and complies with the TI Microwire serial data exchange standard for processor interface. It provides a conversion time of 32 μs, supports ratiometric operation, and accommodates high-voltage inputs via an internal shunt regulator.

Analog To Digital Converters (ADC) Feature Summary

• 8-Bit SAR Architecture: Provides 8-bit resolution with a total unadjusted error of ±1 LSB (max) and a conversion time of 32 μs.
• Multiplexer Options: Includes a 4-channel multiplexer configurable for single-ended or differential inputs via software address logic.
• Serial Interface: Complies with TI Microwire standards, allowing direct interface to COPS processors or standard shift registers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CCWMX' against the manufacturer's current documentation to confirm package type (SOIC-14), temperature range (Commercial 0°C to +70°C), and reel packaging specifications. Ensure compatibility with existing system clock frequencies and voltage levels before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with a 4-channel multiplexer is required. It is suitable for applications needing a serial interface compatible with Microwire standards. Consider the 0°C to +70°C operating temperature range and SOIC-14 surface mount package constraints during PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0831-N/ADC0832-N/ADC0834-N/ADC0838-N series of 8-bit serial I/O A/D converters. The ADC0834 variant specifically offers four analog input channels, distinguishing it from the single-channel ADC0831, dual-channel ADC0832, and eight-channel ADC0838.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the ADC0831, ADC0832, and ADC0838, provided the channel count matches the application requirements. Verify pinout compatibility and ensure the replacement part supports the required serial protocol.
