ADS8695IPWR

Analog To Digital Converters (ADC) Overview

The ADS8695IPWR is an 18-bit, high-speed successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a single-channel input with a sampling rate of 500 kSPS and operates on a single 5-V analog supply with a 1.65-V to 5-V digital I/O supply. The device integrates a programmable gain amplifier (PGA), internal oscillator, and over-voltage protection up to ±20 V. Key performance metrics include a signal-to-noise ratio (SNR) of 92.5 dB, DNL of ±0.6 LSB, and INL of ±1.75 LSB. It supports software-programmable bipolar and unipolar input ranges and communicates via a MultiSPI interface in a TSSOP-16 package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated analog front-end with programmable gain amplifier and internal voltage reference
• Software-selectable bipolar and unipolar input ranges for flexible signal conditioning
• Built-in over-voltage protection capable of withstanding up to ±20 V on inputs
• MultiSPI interface supporting daisy-chain configuration for system scalability

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Medical equipment such as patient monitors and diagnostic imaging devices
• Test and measurement instruments including oscilloscopes and data loggers
• Structural health monitoring and vibration analysis systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix 'IPWR' to ensure the correct TSSOP-16 package and reel packaging are obtained. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure that the ordering information matches the specific revision level required for your design implementation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 500 kSPS speed are required for single-ended signals. It is suitable for designs needing integrated PGA and over-voltage protection to simplify the analog front-end. Compare against ADS8691 for higher speed or ADS8699 for lower power consumption if performance requirements differ.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS869x family of 18-bit SAR ADCs, which also includes the ADS8691 and ADS8699. These parts share similar architectural features but vary in sampling rates. The ADS8695 offers a balanced performance profile between the faster ADS8691 and the lower-power ADS8699, making it versatile for mid-range industrial applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the ADS8691 for higher speed and ADS8699 for lower power. Cross-manufacturer replacements require careful evaluation of pin compatibility, interface protocols, and electrical specifications to ensure seamless integration without hardware modifications.
