ADS8686SIPZAR

Analog To Digital Converters (ADC) Overview

The ADS8686SIPZAR is a dual, simultaneous-sampling, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It features two Successive Approximation Register (SAR) architectures within a single package, providing 16 single-ended input channels with a sampling rate of 1 MSPS per channel. The device operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 1.71 V to 5.25 V. It supports both parallel and serial data interfaces. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 92.2 dB, Differential Nonlinearity (DNL) of 0.35 LSB, Integral Nonlinearity (INL) of 0.75 LSB, and a gain error of 6 LSB. It is housed in an 80-LQFP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPZAR' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure that the ordering information matches the required tape-and-reel packaging specifications. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple channels is critical for maintaining phase coherence. The 16-bit resolution and low noise characteristics make it suitable for high-precision applications. Consider the available PGA settings and reference options to match the specific input signal requirements of the target application design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8686S family of high-performance data converters. It is designed for applications requiring multiple synchronized inputs without the skew associated with sequential sampling ADCs. The LQFP-80 package provides a compact solution for dense PCB layouts while maintaining thermal performance across the extended industrial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the ADS8686SIPT or ADS8686SIPZ, noting any differences in packaging or suffix codes. Verify if older revisions offer equivalent electrical specifications. Ensure that any substitute maintains the dual simultaneous-sampling capability and interface compatibility.
