ADS8865IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8865IDGSR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It 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. The device supports a maximum sampling rate of 400 kSPS and features a true differential input architecture. Communication is handled via a high-speed SPI interface. Key performance metrics include a signal-to-noise ratio (SNR) of 100 dB and a signal-to-noise and distortion ratio (SINAD) of 99.9 dB. It functions within a temperature range of -40°C to +85°C and is housed in a compact 10-VSSOP package.

• Data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your region. Check for moisture sensitivity level (MSL) ratings to determine proper storage and handling procedures before soldering. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 400 kSPS throughput are required for single-channel differential signals. Compare SNR and SINAD specifications against other SAR ADCs if high dynamic range is critical. Consider the 10-VSSOP package dimensions for PCB layout constraints. Verify that the external reference voltage matches the device's input requirements for optimal accuracy.

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 the ADS8861 and ADS8866 models but offers distinct differences in input type and sampling speed. The ADS8865IDGSR is designed to bridge the gap between lower-speed precision ADCs and higher-speed general-purpose converters.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8865IDGS is a pin-compatible tube-packaged alternative. The ADS8861IDGSR offers similar functionality but with a differential input and 1 MSPS speed. The ADS8866IDGSR provides single-ended inputs at 100 kSPS. Verify pinout compatibility and electrical parameters before substitution.
