ADS8866IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8866IDGSR is a 16-bit, 100-kSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input configuration and utilizes a Successive Approximation Register (SAR) architecture. The device operates with an analog supply voltage range of 2.7 V to 3.6 V and a digital supply voltage range of 1.65 V to 3.6 V. It communicates via a standard SPI interface and is housed in a 10-VSSOP package. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 93 dB and a Signal-to-Noise and Distortion Ratio (SINAD) of 92.9 dB. Power consumption is specified at 700 µW, and it functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the order quantity aligns with the manufacturer's standard reel size specifications to ensure proper handling and storage conditions are maintained throughout the supply chain.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input ADC with 16-bit resolution and 100 kSPS throughput is required. Ensure the system design accommodates the separate analog and digital supply voltage ranges. Verify that the external reference voltage requirements match the available precision references compatible with the SAR architecture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER™ family of data converters from Texas Instruments. It shares architectural similarities with other members like the ADS8867, which offers differential inputs, and the ADS8860, which provides higher sampling rates. The IDGSR designation indicates the industrial temperature grade and the specific surface-mount package variant.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8866IDGS is a non-reel version of the same functional device. For differential input requirements, the ADS8867 series serves as a functional alternative within the same power envelope.
