ADC08831IM

Analog To Digital Converters (ADC) Overview

The ADC08831IM is an 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a configurable input multiplexer supporting two channels and operates with a sampling rate of 250 kSPS. The device utilizes a 3-wire serial interface compliant with Microwire standards, enabling compatibility with microcontrollers, DSPs, and shift registers. It functions within an analog and digital supply voltage range of 4.5 V to 6 V. The component is housed in an 8-SOIC package and supports single-ended, differential, or pseudo-differential input configurations.

Analog To Digital Converters (ADC) Feature Summary

• Configurable input multiplexer allows flexible channel selection for dual-channel operation.
• Integrated track/hold function maintains analog voltage stability during the conversion process.
• Automatic low-power mode activation minimizes energy consumption when conversions are inactive.
• Adjustable voltage reference input enables encoding of small analog spans across full resolution.

Analog To Digital Converters (ADC) Applications

• Remote sensing in noisy environments
• General instrumentation systems
• Embedded data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IM' corresponds to the SOIC-8 package and industrial temperature range (-40°C to +85°C) as defined in the official datasheet. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the serial interface configuration matches the target system's Microwire or SPI requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low pin count and simple serial interfacing. The SAR architecture provides adequate speed for moderate bandwidth signals. Consider the external reference requirement if high precision is needed. Verify that the 4.5 V minimum supply voltage aligns with the system power rails.

Analog To Digital Converters (ADC) Part Context

The ADC08831 belongs to a family of 8-bit serial I/O CMOS A/D converters that includes variants like the ADC08832. These devices were originally developed by National Semiconductor and are now supported by Texas Instruments. The IM suffix specifically denotes the plastic small-outline integrated circuit (SOIC) package variant designed for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other parts from the ADC0883x family such as the ADC08832, which shares similar architectural features but may differ in channel configuration. Cross-reference with newer generations of 8-bit SAR ADCs if updated packaging or performance metrics are required.
