ADS8865IDRCT

Analog To Digital Converters (ADC) Overview

The ADS8865IDRCT is a single-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments' microPOWER series. It features a true-differential input architecture and operates at a sampling rate of 400 kSPS using successive approximation register (SAR) technology. The device supports an SPI-compatible serial interface and requires external voltage references. It functions with an analog supply voltage ranging from 2.7 V to 3.6 V and a digital supply voltage from 1.65 V to 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of 98 dB and a power consumption of 2.6 mW. It is housed in a compact 10-VSON package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDRCT corresponds to the tape and reel packaging format required for automated surface-mount assembly. Confirm that the order quantity aligns with standard reel specifications to ensure proper handling and storage conditions are maintained prior to use. Check moisture sensitivity level requirements for reflow soldering profiles.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution 16-bit conversion is required alongside moderate speed up to 400 kSPS. The true-differential input makes it suitable for noisy environments where common-mode noise rejection is critical. Ensure the system design accommodates the separate analog and digital supply rails and provides an appropriate external reference voltage source.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS886x family of micro-power ADCs designed for space-constrained applications. It shares architectural similarities with other members like the ADS8860 and ADS8865IDGSR but differs in package type and specific sampling rates. The VSON-10 package offers a small footprint compared to larger SOIC options while maintaining thermal performance.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8865IDRCR is a direct substitute offering identical electrical characteristics but in a different reel configuration. For pin-compatible alternatives with different speeds, consider the ADS8860 or ADS8866, though resolution and sampling rate differences must be evaluated against system requirements.
