ADS8864IDGS

Analog To Digital Converters (ADC) Overview

The ADS8864IDGS is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 400 kSPS and features a serial peripheral interface (SPI). The device accepts single-ended input signals and requires an external voltage reference. Power consumption is specified at 2.6 mW under typical operating conditions. The analog supply voltage range is 2.7 V to 3.6 V, while the digital supply ranges from 1.65 V to 3.6 V. It is housed in a 10-lead MSOP package and supports operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports daisy-chaining for multi-channel systems
• Includes internal oscillator for simplified clocking
• Miniature package design for space-constrained applications

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 IDGS corresponds to the MSOP-10 tube packaging configuration. Confirm that the external reference voltage requirements align with system design constraints. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-check pinout compatibility if replacing legacy components in existing PCB layouts.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input architecture is required rather than differential signaling. Choose based on the 400 kSPS throughput requirement versus lower-speed alternatives like the ADS8867. Evaluate power budget constraints against the 2.6 mW dissipation figure. Consider the MSOP-10 footprint availability during layout planning.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPower SAR ADC family from Texas Instruments. It shares architectural similarities with the ADS8860 and ADS8867 but differs in input type and sampling speed. The IDGS suffix denotes the specific surface-mount package variant within the broader ADS8864 product line.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8864IDGSR serves as the reel-based alternative offering identical electrical characteristics. ADS8860IDGS provides similar performance but utilizes pseudo-differential inputs instead of single-ended.
