ADS1287IRHFT

Analog To Digital Converters (ADC) Overview

The ADS1287IRHFT is a low-power, high-resolution analog-to-digital converter (ADC) from Texas Instruments. It features a single-channel sigma-delta architecture with 24-bit resolution and a maximum sampling rate of 1000 SPS. The device operates within an extended temperature range of -40°C to +85°C and utilizes a 24-pin VQFN package. Key performance metrics include a signal-to-noise ratio of 113 dB at 1000 SPS with unity gain in High-Resolution Mode, consuming 4.5 mW. In Low-Power Mode, it maintains an SNR of 110 dB while reducing power consumption to 2.4 mW.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-low power consumption optimized for battery-operated or energy-constrained applications
• High-resolution 24-bit sigma-delta conversion with wide bandwidth capabilities
• Dual operational modes allowing trade-off between noise performance and power usage

Analog To Digital Converters (ADC) Applications

• Seismic data acquisition systems
• Energy exploration equipment
• Portable geological monitoring devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHFT corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the operating voltage levels and interface signals match the system design specifications before integration. Ensure compliance with moisture sensitivity level requirements during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring high precision with strict power limitations. It is suitable for applications where moderate sampling rates are sufficient but high dynamic range is critical. Compare against higher-speed ADCs if throughput requirements exceed 1000 SPS.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS128x series of delta-sigma ADCs designed for industrial and scientific measurements. It shares architectural similarities with other members like the ADS1282 and ADS1283 but offers a single-channel configuration tailored for cost-sensitive, space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include other single-channel 24-bit ADCs from the same family such as the ADS1282 or ADS1283 variants, provided pin compatibility and software drivers are verified. Cross-reference datasheets for exact electrical parameter matching.
