ADC12038CIWMX

Analog To Digital Converters (ADC) Overview

The ADC12038CIWMX is a self-calibrating, 12-bit plus sign successive approximation analog-to-digital converter (ADC) featuring an eight-channel multiplexer and sample/hold function. It operates on a single +5V supply with a maximum power consumption of 33 mW. The device supports serial I/O compatible with MICROWIRE standards and includes programmable acquisition time, variable resolution, and digital output word length. It accommodates a 0V to 5V analog input range without requiring zero or full-scale adjustment.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel differential or single-ended multiplexer with analog input sample/hold
• Self-calibration capability adjusting linearity, zero, and full-scale errors to less than ±1 LSB
• MICROWIRE-compatible serial I/O interface with power-down mode consuming 100 μW typical
• Programmable acquisition time and variable digital output word length

Analog To Digital Converters (ADC) Applications

• Medical instruments
• Process control systems
• Test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify component availability status as the ADC12038 family may be obsolete or subject to lifetime buy restrictions. Confirm package type and thermal resistance specifications for the specific suffix variant. Ensure proper bypassing of VA+ and VD+ pins to maintain accuracy.

Analog To Digital Converters (ADC) Selection Notes

Select based on required channel count; this model provides eight channels. Choose between the ADC12030 family (tested at 5 MHz clock) or ADC12H030 family (tested at 8 MHz clock) depending on throughput needs. Ensure external reference voltage is within the 1V to 5V range for optimal performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the Texas Instruments ADC1203x series of 12-bit SAR ADCs. It shares architectural similarities with the ADC12030, ADC12032, and ADC12034 models, differing primarily in the number of multiplexer channels available. The 'CIWM' suffix indicates industrial temperature range and SOIC wide body packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other members of the ADC1203x family such as ADC12030, ADC12032, and ADC12034, provided the channel count difference is acceptable. Verify pin compatibility and software configuration differences when migrating between models.
