ADS7960QDBTRQ1

Analog To Digital Converters (ADC) Overview

The ADS7960QDBTRQ1 is an automotive-grade, single-ended, 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a sampling rate of 1 MSPS and supports up to 12 channels. The device operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. It utilizes a standard SPI-compatible interface for data communication. Key performance metrics include a signal-to-noise ratio (SNR) of 49 dB, differential nonlinearity (DNL) of ±0.3 LSB, and integral nonlinearity (INL) of ±0.3 LSB. The full power bandwidth is 47 MHz, and the typical power consumption is 11.5 mW. It is housed in a TSSOP-38 package and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Low-power architecture designed for battery-operated applications with minimal energy consumption.
• Flexible input configuration supporting single-ended signals across multiple channels.

Analog To Digital Converters (ADC) Applications

• Automotive sensor interfaces for temperature, pressure, and position sensing.
• Battery management systems requiring multi-channel voltage monitoring.
• Industrial data acquisition systems operating in harsh thermal conditions.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel packaging format. Confirm the specific grade designation aligns with automotive quality requirements. Ensure the component source is authorized to guarantee authenticity and traceability. Check for any specific handling instructions related to moisture sensitivity levels indicated on the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 1 MSPS speed are sufficient for the application. Consider the TSSOP-38 package constraints for PCB layout. Evaluate the need for external reference voltage support as the device does not include an internal reference. Compare against higher-resolution alternatives if system accuracy demands exceed 8 bits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7960 family of low-power, high-speed ADCs. It shares architectural similarities with other members like the ADS7953 and ADS7956 but offers distinct channel counts and resolution options. The 'Q' suffix indicates automotive qualification, while 'DBTR' specifies the TSSOP-38 package and reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS7960SDBT for non-automotive grades. For automotive replacements, verify pin compatibility and electrical specifications against the ADS7956Q or ADS7953Q series, ensuring interface and power requirements match.
