ADS8528SPM

Analog To Digital Converters (ADC) Overview

The ADS8528SPM is a 12-bit, eight-channel simultaneous sampling analog-to-digital converter manufactured by Texas Instruments. It features true bipolar inputs and supports both parallel and serial interfaces. The device operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 2.7 V to 5.5 V. It achieves a signal-to-noise ratio (SNR) of 76 dB and functions within a temperature range of -40°C to +125°C. Packaged in a 64-pin LQFP format, it integrates internal oscillators and allows for daisy-chain connectivity.

Analog To Digital Converters (ADC) Feature Summary

• Eight independent SAR ADC channels enable simultaneous signal acquisition at high speeds.
• True bipolar input architecture accommodates wide dynamic range signals without external level shifting.
• Flexible interface options support both parallel data transfer and serial communication protocols.
• Integrated oscillator and daisy-chain capability simplify system design and reduce component count.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure compatibility with existing board layouts regarding the LQFP-64 footprint. Confirm that power supply requirements align with the specified voltage ranges before integration into the final design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight-channel simultaneous sampling is required with 12-bit resolution. Consider the ADS8548 or ADS8568 if higher resolution or different channel counts are needed. Evaluate interface constraints to determine if parallel or serial modes better suit the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS85x8 family of simultaneous sampling ADCs from Texas Instruments. The series includes variants with 14-bit and 16-bit resolutions, offering scalable performance for demanding applications.
