ADS8681WRUMT

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS8681WRUMT is a 16-bit, high-speed successive approximation register (SAR) analog-to-digital converter (ADC) data acquisition system. It operates at a sampling rate of 1MSPS with a single 5V analog supply and supports digital I/O voltages from 1.65V to 5.25V. The device features an integrated differential analog front-end driver circuit, overvoltage protection up to ±20V, and an on-chip 4.096V reference. It offers software-programmable bipolar ranges (±12.288V to ±2.56V) and unipolar ranges (0V to 12.288V). Key performance metrics include a typical signal-to-noise ratio of 80.4dB, total harmonic distortion of -105dB, and a constant resistive input impedance greater than 1MΩ.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'MT' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS3 compliance standards as indicated in official documentation. Ensure the selected variant matches the intended thermal and electrical operating conditions for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed 1MSPS conversion rate is required alongside high-precision 16-bit resolution. It is suitable for applications needing wide dynamic input ranges without external signal conditioning amplifiers. Consider the integrated overvoltage protection if the system must withstand transient voltage spikes exceeding standard input limits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS868xW family, which includes the ADS8685W and ADS8689W variants. These devices share a common architecture but differ primarily in their maximum sampling rates. The ADS8681W represents the highest speed option within this specific series, designed for demanding real-time data acquisition tasks.
