ADC12030CIWM

Analog To Digital Converters (ADC) Overview

The ADC12030CIWM is a self-calibrating 12-bit plus sign successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a two-channel multiplexer with sample-and-hold functionality and serial I/O compatible with MICROWIRE protocols. The device operates on a single +5V supply, consuming a maximum of 33 mW in active mode and 100 μW in power-down mode. Key electrical specifications include a maximum conversion time of 8.8 μs, an integral linearity error of ±1 LSB after auto-calibration, and an analog input range of 0V to 5V. It supports variable resolution, programmable acquisition time, and digital output word length.

Analog To Digital Converters (ADC) Feature Summary

• Self-calibrating architecture ensuring linearity, zero, and full-scale errors are adjusted to less than ±1 LSB.
• Two-channel differential or single-ended multiplexer with integrated sample-and-hold function.
• MICROWIRE-compatible serial I/O interface supporting variable resolution and output word length.
• Single +5V supply operation with low power consumption of 33 mW (max) and 100 μW (typ) in power-down mode.

• Process control systems
• Test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify component availability status prior to procurement, as the ADC12030 family may be obsolete or subject to lifetime buy restrictions. Confirm package type and thermal resistance requirements for the specific application environment. Ensure proper bypassing of VA+ and VD+ pins to maintain accuracy and stability during operation.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC12030CIWM when a 12-bit resolution with self-calibration capabilities is required for single-supply applications. Consider the 8.8 μs maximum conversion time and 5 MHz clock limit for timing constraints. Ensure the analog input signals remain within the 0V to 5V range and that the reference voltage is properly configured between 1V and 5V DC.

Analog To Digital Converters (ADC) Part Context

The ADC12030CIWM belongs to the ADC12030 family, which includes variants with 2, 4, or 8 channels. This specific part number denotes the 2-channel version in a Wide Body SOIC package. It is distinct from the ADC12H030 family, which supports higher clock speeds up to 8 MHz. The 'C' suffix indicates commercial temperature range operation (-40°C to +85°C).

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include ADC12032CIWM (4-channel), ADC12034CIWM (4-channel), and ADC12038CIWM (8-channel). For higher speed requirements, the ADC12H030 series offers similar functionality with an 8 MHz clock capability. Verify pin compatibility and software configuration differences when migrating between channel counts or families.
