ADS8887IDRCT

Analog To Digital Converters (ADC) Overview

The ADS8887IDRCT is an 18-bit, truly differential input successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 200 kSPS and features a serial peripheral interface (SPI). The device 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. It achieves a signal-to-noise ratio (SNR) of 100 dB and a signal-to-noise and distortion ratio (SINAD) of 99.9 dB. Power consumption is rated at 3.4 mW. The component is housed in a 10-VSON package and functions 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 configuration required for automated assembly processes. Confirm that the external reference voltage specifications align with the target application requirements before procurement. Ensure handling procedures account for moisture sensitivity level classifications during storage and reflow soldering operations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 200 kSPS throughput are necessary for high-precision differential measurements. Compare against other ADS888x variants if higher or lower sampling rates are needed, as the family offers options ranging from 400 kSPS down to slower speeds. Ensure the external reference voltage capability matches the desired input signal range without additional scaling circuitry.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments microPOWER ADS888x family of 18-bit SAR ADCs. The family shares common architectural features such as true differential inputs and low power optimization. Variants within the series differ primarily in sampling speed and specific feature sets like busy indicators, allowing designers to balance performance and power consumption across different product lines.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible substitutes within the same family include the ADS8881, ADS8883, and ADS8885. These parts share identical pinouts and functional interfaces but offer different maximum sampling rates. Verify that the alternative part's throughput meets the system timing requirements before substitution.
