ADS8353QPWRQ1

Analog To Digital Converters (ADC) Overview

The ADS8353QPWRQ1 is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for automotive applications. It operates with an analog supply voltage ranging from 4.5 V to 5.5 V and a digital supply voltage between 1.65 V and 5.5 V. The device supports a maximum sampling rate of 600 kSPS per channel and features a serial peripheral interface (SPI). It offers pseudo-differential or single-ended input configurations with an internal or external reference option. Key performance metrics include a signal-to-noise ratio (SNR) of 89 dB, differential nonlinearity (DNL) of ±0.6 LSB, integral nonlinearity (INL) of ±1 LSB, and a gain error of 0.05% FS. It is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix QPWRQ1 to confirm automotive grade classification and TSSOP-16 packaging. Ensure compatibility with AEC-Q100 requirements for your target application. Check datasheet revisions for any recent pinout or electrical characteristic updates before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and 16-bit resolution are required in automotive environments. Compare against the commercial ADS8353IPWR if automotive qualification is unnecessary. Consider the WQFN package variant ADS8353IRTER if board space constraints favor a smaller footprint over the TSSOP form factor.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8353 family of SAR ADCs, which also includes the commercial ADS8353IPWR and the WQFN-packaged ADS8353IRTER. The Q1 suffix denotes automotive qualification, while PWR indicates the TSSOP-16 package. The family shares core architectural features but differs in operating temperature ranges and reliability standards.

Analog To Digital Converters (ADC) Replacement Considerations

The commercial equivalent is the ADS8353IPWR. For a smaller package alternative, consider the ADS8353IRTER. Verify that the replacement meets all functional and environmental requirements of the original design.
