ADS8322Y/2K

Analog To Digital Converters (ADC) Overview

The ADS8322Y/2K is a 16-bit successive-approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input configuration and operates with a sampling rate of 500 kSPS. The device utilizes a parallel interface for data output and includes an internal reference voltage source. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a differential nonlinearity (DNL) of +/- 2 LSB and an integral nonlinearity (INL) of +/- 8 LSB. The component is housed in a TQFP-32 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'Y/2K' against the manufacturer's current datasheet to confirm packaging details, as suffixes often denote reel quantities or tape-and-reel specifications. Ensure compatibility with the required TQFP-32 footprint and check for any lifecycle status changes, such as obsolescence notices, before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, unipolar input ADC with parallel interface is required. It is suitable for applications needing 16-bit accuracy at moderate speeds. Consider alternative models if differential inputs, lower power consumption, or serial interfaces are necessary for the system design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8322 series of 16-bit SAR ADCs. It shares architectural similarities with other devices in the family but is distinguished by its specific input type and interface configuration. The Y/2K designation indicates the commercial grade variant packaged in reels for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may be limited due to the specific parallel interface and unipolar input configuration. Verify electrical parameters and package dimensions before substituting with other 16-bit SAR ADCs from Texas Instruments or other manufacturers.
