ADS8353QPWQ1

Analog To Digital Converters (ADC) Overview

The ADS8353QPWQ1 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 sampling rates up to 600 kSPS and features a serial peripheral interface (SPI). Key performance metrics include a signal-to-noise ratio of 89 dB, differential nonlinearity of ±0.6 LSB, integral nonlinearity of ±1 LSB, and a gain error of 0.05% FS. It functions within a temperature range of -40°C to +125°C and is housed in a TSSOP-16 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix QPWQ1 against the manufacturer's current datasheet to confirm package type and automotive qualification status. Ensure compatibility with required SPI timing parameters and voltage levels before integration. Cross-reference the AEC-Q100 grade requirements with system specifications to validate suitability for the intended operational environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 16-bit resolution is required at speeds up to 600 kSPS. Consider the TSSOP-16 package constraints and the need for separate analog and digital supply domains. Evaluate the SNR and linearity specifications against system noise budgets. Confirm that the operating temperature range meets the environmental demands of the application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8353 family of automotive-grade ADCs. It shares core architectural features with other members of the series but differs in packaging and specific qualification markings. The QPWQ1 designation indicates a specific tape-and-reel or tube configuration variant within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS8353 variants with different suffixes for package changes. Verify if ADS8358 or ADS8357 offer compatible pinouts or performance upgrades. Consult the manufacturer's obsolescence notices for any discontinued sub-types within the ADS835x family.
