ADS8665IPWR

Analog To Digital Converters (ADC) Overview

The ADS8665IPWR is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input architecture and operates with an analog supply voltage range of 4.75V to 5.25V and a digital supply range of 1.65V to 5.25V. The device supports a maximum sampling rate of 500kSPS and utilizes a serial peripheral interface (SPI) for data communication. Key integrated features include an internal oscillator, a programmable gain amplifier (PGA), and over-voltage protection on the input channel. It is housed in a 16-TSSOP package and is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier allows flexible signal conditioning without external components.
• Built-in over-voltage protection safeguards the input stage against excessive voltage levels.
• Internal oscillator eliminates the need for external clock sources, simplifying system design.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution single-channel acquisition
• Portable instrumentation benefiting from low power consumption and wide supply ranges
• Data acquisition modules in harsh environments due to extended temperature ratings

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPWR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the digital supply voltage requirements align with the target logic levels, as the device supports a wide range from 1.65V to 5.25V. Ensure compliance with RoHS3 standards if required by the final assembly specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input configuration is sufficient, as opposed to differential variants like the ADS8661. The presence of an internal PGA distinguishes it from basic SAR ADCs, reducing bill-of-materials complexity. Consider the 500kSPS speed limit against application bandwidth needs before choosing over higher-speed family members.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS866x family of 12-bit SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS8661 but differs in input type and sampling speed. The IPWR suffix indicates a reel-packaged version suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8665IPW is the tube-packaged equivalent of this part number. For differential input applications, the ADS8661 series offers similar resolution but with different input configurations and higher sampling rates.
