ADS8885IDRCR

Analog To Digital Converters (ADC) Overview

The ADS8885IDRCR is a single-channel, 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 400 kSPS and features a truly differential input architecture. The device utilizes an SPI-compatible digital interface for data communication. Power requirements include an analog supply voltage range of 2.7 V to 3.6 V and a separate digital I/O supply range of 1.65 V to 3.6 V. Key performance metrics specify a signal-to-noise ratio of 100 dB and a signal-to-noise and distortion ratio of 99.9 dB. Total power consumption is rated at 2.6 mW. The component is housed in a 10-pin VSON package and supports operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required humidity sensitivity levels and moisture management protocols during storage and assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 400 kSPS throughput are required within a minimal physical footprint. The separate digital supply allows for direct interfacing with 1.8 V or 3.3 V logic families without level shifting. Consider the external reference requirement and the availability of compatible precision voltage references for optimal system accuracy.

Analog To Digital Converters (ADC) Part Context

This device belongs to the microPOWER™ family of ADCs from Texas Instruments, designed for space-constrained applications. It shares architectural similarities with other members like the ADS8881 and ADS8883, differing primarily in sampling speed and resolution. The IDRCR suffix specifically denotes the industrial temperature range and the 10-VSON surface-mount package configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8885IDGSR offers identical electrical performance but utilizes an MSOP-10 package instead of the VSON-10 form factor. Designers must evaluate PCB layout constraints and thermal dissipation requirements when substituting between these package types.
