ADS8528SPMR

Analog To Digital Converters (ADC) Overview

The ADS8528SPMR is a high-performance analog-to-digital converter manufactured by Texas Instruments, featuring eight simultaneous sampling channels with 12-bit resolution. It utilizes a Successive Approximation Register (SAR) architecture to achieve a maximum sampling rate of 600 kS/s per channel. The device supports both parallel and serial interfaces, including SPI compatibility, and allows for daisy-chaining multiple units. It 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. The component is housed in a 64-pin LQFP package and is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel simultaneous sampling capability ensures precise time-alignment of input signals across all channels.
• Dual interface flexibility allows selection between parallel and serial communication modes for system integration.
• Daisy-chainable architecture enables efficient connection of multiple devices to reduce pin count requirements.
• Integrated oscillator simplifies clock distribution and reduces external component count.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical imaging equipment needing synchronized signal capture
• Structural health monitoring sensors
• Vibration analysis and acoustic testing platforms

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SPMR' indicates the tape-and-reel packaging variant when ordering. Confirm that the 12-bit resolution matches the design requirements, as this part number belongs to a family offering higher resolutions. Ensure the LQFP-64 footprint aligns with the PCB layout specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS8528SPMR when eight-channel simultaneous sampling at 12-bit resolution is required. Consider the SAR architecture for moderate speed applications up to 600 kS/s. Evaluate the power supply constraints, as the device requires distinct analog and digital voltage rails. Verify interface compatibility with the host microcontroller or DSP regarding parallel versus serial mode support.

Analog To Digital Converters (ADC) Part Context

The ADS8528SPMR is part of the ADS85x8 family of simultaneous sampling ADCs from Texas Instruments. This family includes variants with 14-bit and 16-bit resolutions, such as the ADS8548 and ADS8568. All members share similar architectural features, including the SAR core and dual interface options, but differ in resolution and potentially performance metrics like SNR.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8548SPMR offers 14-bit resolution with similar sampling rates. The ADS8568SPMR provides 16-bit resolution. These parts are pin-compatible within the same package type but require verification of resolution-specific performance parameters.
