ADC12030CIWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12030CIWMX/NOPB is a self-calibrating, 12-bit plus sign successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a configurable input multiplexer supporting differential or single-ended channels and includes an integrated sample/hold function. The device operates on a single +5V supply with a maximum power consumption of 33 mW. It utilizes a MICROWIRE-compatible serial interface for data exchange. Key electrical specifications include a maximum integral linearity error of ±1 LSB after auto-calibration, a conversion time of up to 8.8 µs, and an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Self-calibrating architecture that adjusts linearity, zero, and full-scale errors to less than ±1 LSB without external adjustment.
• Configurable multiplexer supporting 2, 4, or 8 channels in differential, pseudo-differential, or single-ended modes.
• MICROWIRE-compatible serial I/O interface with programmable acquisition time and variable digital output word length.
• Low power consumption of 33 mW (max) with a typical power-down current of 20 µA.

Analog To Digital Converters (ADC) Applications

• Medical instruments requiring precise signal acquisition.
• Process control systems utilizing multi-channel sensor inputs.
• Test equipment needing high-resolution analog-to-digital conversion.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NOPB' against the manufacturer's current product availability status, as certain devices within this family may be obsolete or subject to lifetime buy restrictions. Confirm package integrity for the SOIC-16 variant prior to integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC12030 variant specifically when a two-channel multiplexer configuration is required, distinguishing it from the four-channel (ADC12034) or eight-channel (ADC12038) alternatives. Ensure the system clock frequency does not exceed 5 MHz, as the ADC12030 family is tested at this limit compared to the 8 MHz capability of the ADC12H030 series.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1203x family of 12-bit SAR ADCs. It shares architectural similarities with the higher-speed ADC12H03x series but is optimized for lower clock frequencies (5 MHz vs 8 MHz). The part number indicates a commercial temperature grade (-40°C to +85°C) and a lead-free (NOPB) RoHS-compliant packaging option.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacement options within the same family include the ADC12032, ADC12034, and ADC12038, provided the channel count requirements align with the application design.
