ADS8509IBDWR

Analog To Digital Converters (ADC) Overview

The ADS8509IBDWR 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 features a serial peripheral interface (SPI). The device supports both internal and external reference voltages and accepts single-ended inputs. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 88 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±2 LSB. The component is housed in a 20-lead SOIC package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'W' indicates tape-and-reel packaging when sourcing components. Confirm that the IB designation corresponds to the industrial temperature grade requirements for your specific deployment environment. Ensure compatibility with existing SPI bus configurations before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high resolution and moderate speed with a serial interface. Consider the ADS8509IDWR if commercial temperature range suffices. Evaluate power consumption constraints against the specified 155 mW dissipation. Verify input voltage ranges match the single-ended specification without additional scaling circuitry.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS8509 series of 16-bit SAR ADCs from Texas Instruments. It shares architectural similarities with other devices in the family but differs in pin count and interface specifics compared to parallel variants like the ADS8505. The IBDW variant serves as the basis for the reel-packaged IBDWR version.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8509IBDW is the tube-packaged equivalent of this part number. The ADS8509IDWR is available for commercial temperature range applications. Cross-reference pinouts carefully when substituting with related SAR ADC models.
