ADS7854IRTER

Analog To Digital Converters (ADC) Overview

The ADS7854IRTER is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 1.65 V to 5.5 V. The device supports a sampling rate of 1 MSPS per channel and features a serial peripheral interface (SPI). Key performance metrics include a signal-to-noise ratio (SNR) of 88 dB and a signal-to-noise and distortion ratio (SINAD) of 84.6 dB. It consumes 45 mW of power and functions within a temperature range of -40°C to +125°C. The component is housed in a 16-WQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with synchronous sampling capability for simultaneous acquisition.
• Flexible reference configuration supporting both internal and external voltage references.
• Low-power operation optimized for battery-driven applications.
• Compact surface-mount packaging designed for space-constrained circuit boards.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition.
• Medical instrumentation devices needing high-resolution signal conversion.
• Automotive sensor interfaces operating under wide temperature conditions.
• Test and measurement equipment utilizing precise analog front ends.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRTER' corresponds to the WQFN-16 package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly line. Ensure the supplier provides official datasheets matching the Texas Instruments part number to validate electrical characteristics against your design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the ADS7853 variant if higher signal-to-noise performance is required, as indicated by the 88 dB SNR specification. Consider the ADS7854IPWR if a TSSOP-16 package is preferred over the WQFN form factor. Verify that the digital supply voltage range aligns with the system logic levels, as it supports down to 1.65 V.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS785x series of low-power, 14-bit ADCs from Texas Instruments. It shares architectural similarities with the ADS7853 and ADS7851 but offers distinct performance characteristics regarding noise and input types. The series is designed for applications demanding precision and speed in a compact footprint.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7853IRTER: Similar SAR architecture but lower SNR (82 dB). ADS7854IPWR: Identical electrical performance but utilizes a TSSOP-16 package instead of WQFN-16. ADS7851IRTER: Higher sampling rate (1.5 MSPS) but different input structure (differential only).
