ADS1113QNKSRQ1

Analog To Digital Converters (ADC) Overview

The ADS1113QNKSRQ1 is a 16-bit, low-power, delta-sigma analog-to-digital converter (ADC) designed for automotive applications. It features a single differential input channel and operates with an I2C serial interface. The device supports sampling rates up to 860 samples per second (SPS). It functions within an operating temperature range of -40°C to +125°C and utilizes a UQFN-10 package. This component integrates a programmable gain amplifier and an internal reference, eliminating the need for external components in many configurations.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Automotive sensor signal conditioning
• Battery monitoring systems
• Temperature measurement interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RQ1' confirms AEC-Q100 automotive qualification and tape-and-reel packaging format. Confirm the UQFN-10 package dimensions against the official datasheet mechanical drawing prior to PCB layout finalization. Ensure voltage levels on the I2C bus match the device's specified logic thresholds.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution, single-ended or differential input ADC is required for automotive environments. The fixed 860 SPS maximum rate suits low-frequency sensing tasks. Compare power consumption requirements against the device's active and shutdown modes. Verify that the I2C address configuration meets system bus addressing constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS111x family of precision ADCs. The 'Q' prefix indicates automotive qualification, while 'NK' denotes the UQFN-10 package type. The 'SRQ1' suffix typically specifies reel quantity and automotive grade status. It serves as a compact solution for replacing discrete sensor conditioning circuits in space-constrained automotive modules.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include other ADS111x variants with different package options or channel counts, provided the interface and resolution requirements remain consistent. Cross-model substitution requires verification of register compatibility and physical footprint alignment.
