ADS8661IPWR

Analog To Digital Converters (ADC) Overview

The ADS8661IPWR is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single input channel supporting differential, pseudo-differential, and single-ended configurations with a sampling rate of 1.25 MSPS. The device operates on dual power supplies: 4.75V to 5.25V for analog circuits and 1.65V to 3.3V for digital logic. It integrates an internal oscillator and reference, housed in a 16-TSSOP package. Key performance metrics include a signal-to-noise ratio of 74 dBFS, differential nonlinearity of 0.1 LSB, integral nonlinearity of 0.15 LSB, and gain error of 0.01% FSR.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and temperature grade. Confirm that the component meets RoHS3 compliance requirements for your region. Check for any recent product change notices regarding marking or assembly materials before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high speed is required for single-channel applications. Consider alternative models within the ADS866x family if different sampling rates or additional channels are needed. Ensure the system design accommodates the separate analog and digital supply voltage requirements specified in the electrical characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS866x series of 12-bit high-speed SAR ADCs from Texas Instruments. The IPWR suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly. It shares architectural similarities with other devices in the family but is distinct in its specific sampling rate and pinout configuration.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8661IPW is the same device in a tube package instead of tape and reel. ADS8661WRUMR offers the same functionality in a WQFN-16 package.
