ADS127L01IPBS

Overview

The ADS127L01IPBS is a single-channel, 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It supports data rates up to 512 kSPS with a passband up to 230 kHz. The device features an SNR of 115.5 dB at OSR 256 and SINAD of 115.13 dB. It operates on a 2.7 V to 3.6 V analog supply and a 1.7 V to 3.6 V digital supply. Power consumption ranges from 9 mW to 26 mW depending on the mode. The offset drift is 1.5 µV/°C and gain drift is 0.2 ppm/°C. It uses a 32-TQFP package and supports SPI interfaces.

Feature Summary

• High-order chopper-stabilized modulator for low drift and noise
• Multiple digital filter options including low-latency and wideband filters
• Daisy-chainable serial interface compatible with SPI and frame-sync modes

Applications

• Vibration and modal analysis
• Data acquisition systems
• Acoustics and dynamic strain gauges
• Power quality analysis

Procurement Notes

Verify the specific suffix IPBS corresponds to the TQFP-32 tray packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact speed grade and package variant required for your design implementation.

Selection Notes

Select this component when high AC performance and DC accuracy are required in a single-channel application. Consider the available operating modes to balance power consumption against resolution needs. Verify that the external reference voltage and clock source meet the specified input requirements for optimal SNR performance.

Part Context

This part belongs to the ADS127L01 series of broadband ADCs. It shares architectural similarities with other devices in the family but differs in channel count and specific package options. The IPBS suffix denotes the surface-mount TQFP-32 package variant suitable for automated assembly processes.

Replacement Considerations

Check for ADS127L01IPBSR if reel packaging is preferred over trays. Evaluate ADS127L11 variants if higher sampling rates or different input configurations are needed.
