ADC12038CIWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12038CIWMX/NOPB is a self-calibrating 12-bit plus sign successive approximation analog-to-digital converter featuring an 8-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, allowing for variable resolution and conversion rates. Key electrical specifications include a maximum throughput time of 14 µs, integral linearity error of ±1 LSB, and an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Self-Calibrating Architecture: Automatically adjusts linearity, zero, and full-scale errors to less than ±1 LSB.
• 8-Channel Multiplexer: Supports differential or single-ended input configurations with programmable acquisition time.
• Serial Interface: MICROWIRE-compatible serial I/O reduces pin count and simplifies system integration.
• Low Power Consumption: Maximum power dissipation is 33 mW, with typical power-down current of 20 µA.

Analog To Digital Converters (ADC) Applications

• Medical Instruments
• Process Control Systems
• Test Equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify component availability as the ADC12038 family may be obsolete or on lifetime buy status. Confirm package type (SOIC-20) and ensure proper bypassing of VA+ and VD+ pins to maintain accuracy. Check for RoHS compliance details in official documentation before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC12038 when an 8-channel multiplexed input is required alongside 12-bit resolution. Ensure the application can accommodate the 14 µs maximum throughput time. Verify that the external reference voltage falls within the 1 VDC to 5.0 VDC range for optimal performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1203x family of high-speed, low-power A/D converters. It shares architectural similarities with the ADC12030, ADC12032, and ADC12034, differing primarily in the number of multiplexer channels. The 'NOPB' suffix indicates lead-free packaging compliant with environmental standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC12030, ADC12032, and ADC12034, though channel counts vary. For higher speed requirements, consider the ADC12H038. Verify pin compatibility and software configuration differences when migrating between variants.
