ADS8885IDRCT

Analog To Digital Converters (ADC) Overview

The ADS8885IDRCT is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input channel and operates with a maximum sampling rate of 400 kSPS. The device utilizes a serial peripheral interface (SPI) for data communication. It requires an analog supply voltage between 2.7 V and 3.6 V and a digital supply voltage ranging from 1.65 V to 3.6 V. Key performance metrics include a signal-to-noise ratio of 100 dB and a signal-to-noise and distortion ratio of 99.9 dB. The component is housed in a 10-VSON package and supports daisy-chainable configurations.

Analog To Digital Converters (ADC) Feature Summary

• Supports daisy-chainable operation for multi-channel systems
• Integrates an internal oscillator to reduce external component count
• Features a compact VSON-10 package for space-constrained designs

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDRCT indicates tape-and-reel packaging when sourcing components. Confirm that the external reference requirement aligns with system design constraints, as the device does not include an internal voltage reference. Ensure compatibility with the specified SPI interface timing requirements during integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high resolution and low power consumption within a small footprint. Compare against the ADS8881 if a higher sampling rate of 1 MSPS is necessary, noting the increased power dissipation. Ensure the system can accommodate the required dual supply voltages for analog and digital sections.

Analog To Digital Converters (ADC) Part Context

This component belongs to the microPOWER family of ADCs from Texas Instruments. It shares architectural similarities with the ADS8881 and ADS8883 models, differing primarily in sampling speed and power consumption profiles. All variants in this series utilize the same VSON-10 package and SPI interface.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8881IDRCT serves as a functional alternative within the same package, offering a higher sampling rate of 1 MSPS but with increased power consumption. Designers should verify pin compatibility and adjust power management strategies when substituting these parts.
