ADS1271IBPWR

Overview

The ADS1271IBPWR is a single-channel, 24-bit industrial delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 105 kSPS and supports a signal bandwidth up to 51 kHz. The device features differential input configuration and communicates via an SPI interface. It requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply between 1.65 V and 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of 109 dB, a differential nonlinearity (DNL) of ±1 LSB, and an integral nonlinearity (INL) of ±0.0015% FSR. The component is housed in a 16-pin TSSOP package and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Combines high DC accuracy with high AC performance for precision measurement applications
• Supports daisy-chainable operation for multi-channel system expansion
• Integrates digital filtering with low passband ripple and high stopband attenuation

Applications

• Test and measurement equipment
• Vibration analysis systems
• Machine tool monitoring
• Medical instruments

Procurement Notes

Verify the suffix 'IBPWR' corresponds to the tape-and-reel packaging variant rather than the tube-packaged 'IBPW'. Confirm that the specific revision level matches the required design specifications. Ensure compatibility with the external reference voltage requirements specified in the datasheet. Check for moisture sensitivity level compliance during storage and handling procedures prior to assembly.

Selection Notes

Select this component when a single-channel ADC requires both high resolution and significant signal bandwidth simultaneously. It is suitable for designs needing daisy-chain capability without sacrificing dynamic performance. Consider the power consumption constraints relative to the 105 kSPS data rate. Evaluate the thermal management requirements given the operating temperature range and power dissipation characteristics.

Part Context

This part belongs to the ADS1271 series of high-bandwidth industrial ADCs. It represents a combination of delta-sigma architecture optimized for both DC precision and AC signal integrity. The IBPWR designation indicates the reel-packaged version of the standard ADS1271 device, facilitating automated surface-mount assembly processes.

Replacement Considerations

ADS1271IBPW is the tube-packaged equivalent of the same functional device.
