Overview
The ADS127L14IRSHR is a Texas Instruments analog-to-digital converter featuring eight simultaneous-sampling channels with 24-bit resolution. It utilizes a sigma-delta architecture and supports an input type of differential, pseudo-differential, or single-ended signals. The device operates with an analog supply voltage ranging from 2.85 V to 5.5 V and a digital supply voltage between 1.65 V and 1.95 V. It employs a parallel interface for data output and achieves a signal-to-noise ratio (SNR) of 110 dB.
Feature Summary
- Eight-channel simultaneous sampling capability
- 24-bit resolution with sigma-delta architecture
- Parallel interface for high-speed data transfer
- Supports differential, pseudo-differential, and single-ended inputs
Applications
- Industrial process control systems
- Vibration monitoring applications
- Acoustic emission testing equipment
Procurement Notes
Verify the specific package variant, as the ADS127L14 series includes both IRSHR (VQFN-56) and IRSHT (VQFN-56) suffixes which may differ in reel packaging specifications. Confirm that the required parallel interface aligns with the system design, as other variants in this family utilize SPI interfaces. Ensure power supply rails match the specified analog and digital voltage ranges during integration.
Selection Notes
Select the ADS127L14IRSHR when eight simultaneous channels are required with a parallel interface. Compare against the ADS127L14IRSHT if cut-tape availability is preferred over reel packaging, noting they share identical electrical characteristics. Consider the ADS127L18IRSHR if higher channel counts are needed, or the ADS127L14IRSHT if an SPI interface is acceptable for reduced pin count.
Part Context
This component belongs to the ADS127L18 family of low-power, high-speed analog-to-digital converters. The ADS127L14 variant specifically provides four fewer channels than the ADS127L18 while maintaining similar performance metrics such as resolution and sampling rates. It shares the same VQFN-56 package footprint and electrical specifications regarding power supplies and SNR.
