ADS8322YB/2K

Analog To Digital Converters (ADC) Overview

The ADS8322YB/2K is a 16-bit, unipolar analog-to-digital converter (ADC) from Texas Instruments. It features a successive approximation register (SAR) architecture with a single-ended input and parallel interface. The device operates at a sampling rate of 500 kSPS and requires 4.75 V to 5.25 V for both analog and digital supplies. Key performance metrics include a differential nonlinearity (DNL) of +/- 2 LSB and an integral nonlinearity (INL) of +/- 6 LSB. It consumes 85 mW of power and includes an internal reference. The component is housed in a TQFP-32 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal voltage reference to simplify system design.
• Supports high-speed data acquisition with a 500 kSPS sampling rate.
• Utilizes a parallel output interface for direct microcontroller connection.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data conversion.
• Medical instrumentation such as patient monitoring devices.
• Data acquisition systems for scientific instruments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '2K' against the official datasheet to confirm packaging details, as standard listings may indicate tape-and-reel or cut-tape formats. Confirm RoHS compliance status through the manufacturer's documentation. Check for end-of-life notifications, as similar ADS8322 variants have been marked obsolete in some distributor records. Ensure the TQFP-32 package availability matches your PCB footprint requirements before ordering.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 500 kSPS speed are required for single-channel applications. The parallel interface necessitates more GPIO pins compared to SPI alternatives like the ADS8326. Consider the 85 mW power consumption and 5V supply requirement for compatibility with existing system rails. Verify that the +/- 6 LSB INL specification meets the accuracy needs of the target application.

Analog To Digital Converters (ADC) Part Context

The ADS8322 belongs to the ADS832x family of 16-bit ADCs designed for precision applications. It shares architectural similarities with other SAR converters but distinguishes itself through its parallel interface and internal reference. This model serves as a bridge between lower-speed serial ADCs and higher-throughput pipeline converters, offering a balance of resolution and speed for mid-range data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers for ADS8322YB/2K were not found in the provided source material. Engineers should consult the official TI datasheet for recommended pin-compatible or functionally equivalent alternatives, as generic industry knowledge cannot verify specific cross-references without fabrication risks.
