Overview
The ADS1282HIPWR is a high-performance, ultra-high-resolution delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 31-bit resolution and supports two differential input channels with an integrated programmable gain amplifier (PGA). The device operates at sampling rates up to 4 kS/s and utilizes a serial peripheral interface (SPI) for digital communication. It requires a single external reference voltage and functions within an extended industrial temperature range of -55°C to +125°C. Power consumption is specified at 25 mW, making it suitable for low-power applications requiring high precision.
Feature Summary
- Ultra-high resolution with 31-bit effective output data rate capability
- Integrated dual-channel sigma-delta architecture with programmable gain amplifier
- Extended industrial operating temperature range supporting harsh environments
- Low power consumption design optimized for battery-operated systems
Applications
- Seismic data acquisition systems
- High-precision multi-channel measurement instrumentation
- Industrial process control monitoring
- Medical diagnostic equipment requiring high signal integrity
Procurement Notes
Verify the specific suffix 'H' indicates the extended temperature grade (-55°C to +125°C) compared to standard variants. Confirm package type is TSSOP-28. Ensure compatibility with required SPI clock speeds and reference voltage specifications before ordering.
Selection Notes
Select this component when application requirements demand high resolution over high speed. Compare against ADS1282IPW if lower temperature ranges are sufficient. Verify that the 4 kS/s maximum sampling rate meets system throughput needs. Check PGA gain settings against expected input signal amplitudes.
Part Context
This part belongs to the ADS128x family of ultra-high-resolution ADCs designed for demanding measurement applications. It shares architectural similarities with the ADS126x series but offers higher resolution at lower data rates. The 'H' suffix denotes the extended temperature variant, distinguishing it from commercial grade parts like the ADS1282IPW.
Replacement Considerations
ADS1282IPWR serves as a direct functional substitute with identical electrical characteristics but a limited commercial temperature range (-40°C to +85°C). Verify thermal constraints in the target application before substituting.
