ADS8664IDBTR

Analog To Digital Converters (ADC) Overview

The ADS8664IDBTR is a quad-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 1.65 V and 5.25 V. The device supports a sampling rate of 500 kSPS per channel and features an internal 4.096 V reference. Key electrical specifications include a signal-to-noise ratio of 73.85 dB, differential nonlinearity of 0.5 LSB, and integral nonlinearity of 0.5 LSB. It draws 65 mW of power and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent single-ended input channels with programmable gain amplifier functionality for flexible signal conditioning.
• Features an internal voltage reference and daisy-chainable SPI interface to simplify system architecture and reduce pin count.
• Includes over-voltage protection on all input pins to enhance robustness in industrial environments.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation utilizing low-power SAR ADC technology
• Factory automation and monitoring applications with isolated or grounded signals

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IDBTR against the manufacturer's official datasheet to confirm the TSSOP-38 package and reel packaging configuration. Ensure that the component meets RoHS compliance requirements as specified in the technical documentation before integration into production assemblies.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a quad-channel solution with 12-bit resolution and 500 kSPS throughput is required. It is suitable for designs needing an integrated reference and PGA to minimize external component count. Verify that the single-ended input requirement aligns with the sensor interface, as differential inputs are not supported natively.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8664 family of high-speed, low-power SAR ADCs. It shares architectural similarities with other devices in the series but is distinguished by its specific 12-bit resolution and quad-channel configuration. The IDBTR suffix indicates the tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) FAQ

Does the ADS8664 support differential input signals?

No, the ADS8664 is designed specifically for single-ended input signals only.

What is the maximum sampling rate per channel?

Each of the four channels can operate at a maximum sampling rate of 500 kSPS.

Is an external voltage reference required?

An internal voltage reference of 4.096 V is included, so an external reference is not strictly necessary unless higher precision is required.
