ADS831E

Analog To Digital Converters (ADC) Overview

The ADS831E is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-channel differential or single-ended input and operates with an analog supply voltage range of 2.7V to 5.5V. The device supports a maximum sampling rate of 200ksps and utilizes a serial interface compatible with standard SPI protocols for data output. It is housed in a compact 8-pin SOIC package, suitable for surface-mount applications. The operational temperature range extends from -40°C to +85°C, ensuring reliability in industrial environments.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 12-bit resolution conversion using SAR architecture
• Flexible input configuration supporting both differential and single-ended signals
• Low power consumption optimized for battery-operated systems
• Single-supply operation simplifying power design requirements

Analog To Digital Converters (ADC) Applications

• Portable instrumentation and metering devices
• Industrial process control signal acquisition
• Data acquisition systems requiring moderate speed and resolution
• Battery-powered measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure compatibility with existing PCB footprint designs before procurement. Check for any recent product lifecycle notices regarding availability or obsolescence.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 12-bit accuracy and 200ksps throughput is required. Consider the single-channel limitation compared to multi-channel alternatives. Evaluate power budget constraints against the specified supply voltage range. Verify that the SPI interface timing meets the system controller's capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS831 belongs to Texas Instruments' family of low-power, high-speed ADCs. It serves as a cost-effective solution for applications needing more resolution than 8-bit converters but less complexity than 16-bit parts. The device complements other SAR ADCs in the portfolio by offering a specific trade-off between speed, resolution, and pin count.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades within the ADS83x series. Verify if newer generations offer improved linearity or lower noise without changing the board layout. Ensure substitute parts maintain the same supply voltage and interface compatibility.
