ADS8865IDGS

Analog To Digital Converters (ADC) Overview

The ADS8865IDGS is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 400 kSPS and features true differential inputs. The device utilizes an SPI-compatible serial interface for data communication. It requires an external voltage reference and supports 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 component is housed in a 10-lead MSOP package and is rated for operation within a temperature range of -40°C to +85°C.

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 selected variant matches the required operating temperature range and pinout configuration for the target PCB layout. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high resolution is required for single-ended or differential signal conditioning. Ensure the system architecture accommodates the need for an external voltage reference. Verify that the microcontroller interface supports the required SPI clock speeds and timing constraints defined in the electrical characteristics section of the datasheet.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS886x family of microPower ADCs from Texas Instruments. It shares architectural similarities with the ADS8867 and ADS8860 but offers distinct performance trade-offs regarding input type and sampling speed. The MSOP-10 package allows for space-constrained designs compared to larger QFN or TSSOP alternatives within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8865IDGSR serves as the reel-based alternative to the tube-packaged IDGS version. Designers requiring different input configurations may consider the ADS8867 for differential inputs or the ADS8860 for higher speed single-ended applications.
