ADS8509IBDWRG4

Analog To Digital Converters (ADC) Overview

The ADS8509IBDWRG4 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 250 kSPS and supports both single-ended and pseudo-differential input configurations. The device functions on dual power supplies ranging from 4.75 V to 5.25 V for both analog and digital domains. Key performance metrics include a signal-to-noise ratio of 88 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±2 LSB. It features an internal oscillator and daisy-chainable serial interface capabilities within a 20-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Provides flexible reference options including internal and external configurations

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Medical instrumentation utilizing precise analog signal digitization
• Data acquisition modules in automated test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging versus tube variants when sourcing. Confirm RoHS compliance status through official manufacturer documentation as regulatory requirements evolve. Ensure the ordering part number matches the exact temperature grade and package style required for the design. Cross-reference with the latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications demanding 16-bit resolution at moderate speeds up to 250 kSPS. Consider the single-channel architecture when designing for cost-sensitive or space-constrained boards. Evaluate the need for daisy-chaining capabilities if multiple converters are required in the signal chain. Verify that the 5V supply voltage aligns with the system's power distribution network.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8509 family of 16-bit SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS8508 but offers higher resolution. The device is designed for general-purpose data acquisition tasks where accuracy and speed balance are critical. It serves as a standalone solution for converting analog signals into digital data for microprocessors or DSPs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8509IBDW is a compatible alternative offering identical electrical specifications and pinout. Verify that the packaging difference between reel and tube does not impact assembly processes. No direct functional substitutes exist within the same series that offer different channel counts without redesigning the schematic.
