ADS8867IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8867IDGSR is a 16-bit, single-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates with a sampling rate of 100 kSPS and features true differential inputs. 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 utilizes an external reference voltage of 5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 96 dB and a signal-to-noise and distortion ratio (SINAD) of 96.4 dB. The component is housed in a 10-MSOP package and supports SPI interface communication.

Analog To Digital Converters (ADC) Feature Summary

• Supports daisy-chainable operation for multi-channel systems
• Integrates an internal oscillator to reduce external component count
• Features a compact MSOP-10 package for space-constrained designs

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered data acquisition devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGSR corresponds to the tape-and-reel packaging configuration rather than tube packaging when sourcing. Confirm that the external reference voltage requirements align with the system design, as the device does not include an internal reference. Ensure compatibility with the required SPI protocol settings for the target microcontroller or DSP interface.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 100 kSPS throughput are required in a small form factor. The true differential input architecture makes it suitable for noise-sensitive applications. Compare against the ADS8860 if higher sampling rates are needed, noting that the ADS8860 offers 1 MSPS but may have different input configurations. Ensure the power supply rails match the specified 2.7 V to 3.6 V analog and 1.65 V to 3.6 V digital ranges.

Analog To Digital Converters (ADC) Part Context

The ADS8867 belongs to the microPOWER family of ADCs from Texas Instruments, designed for low-power, high-precision applications. It shares architectural similarities with other members like the ADS8860 but differs in sampling speed and input type. The IDGSR suffix indicates the surface-mount MSOP-10 package variant supplied in tape-and-reel format for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8867IDGS: Identical electrical specifications but packaged in a tube instead of tape-and-reel. Suitable for manual assembly or different handling requirements.
