ADS8881IDRCR

Analog To Digital Converters (ADC) Overview

The ADS8881IDRCR is a single-channel, 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and features a truly differential input architecture. The device utilizes an SPI-compatible serial interface for data communication. Power requirements include an analog supply voltage range of 2.7 V to 3.6 V and a digital I/O supply range of 1.65 V to 3.6 V. Key performance metrics specify a signal-to-noise ratio (SNR) of 100 dB and a signal-to-noise and distortion ratio (SINAD) of 99.9 dB. The component consumes 5.5 mW of power and functions within a temperature range of -40°C to +85°C. It is housed in a compact 10-pin VSON package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm packaging configuration. The IDRCR designation indicates tape and reel packaging, distinct from tube variants. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with external reference voltage specifications required for optimal SNR performance.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 18-bit resolution and 1 MSPS throughput are required for differential signals. Compare power consumption against lower-speed variants if energy efficiency is critical. Verify that the 10-VSON package dimensions fit the target PCB layout constraints. Ensure the host microcontroller supports the required SPI clock speeds and timing parameters.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS8881 family of microPower SAR ADCs from Texas Instruments. The family includes variants with different packages such as MSOP-10 and VSON-10. Other members like the ADS8885 offer similar resolution but lower sampling rates. The series is designed for applications balancing precision, speed, and low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8881IDRCT serves as a functional equivalent with identical electrical characteristics but differs in packaging format. Verify pinout compatibility and thermal performance when substituting between reel and tube versions.
