ADS1114BQDGSRQ1

Analog To Digital Converters (ADC) Overview

The ADS1114BQDGSRQ1 is a 16-bit analog-to-digital converter (ADC) from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It utilizes a sigma-delta architecture with an internal reference and programmable gain amplifier (PGA). The device supports I2C communication and offers configurable input modes including differential and single-ended connections via an integrated multiplexer. It operates on a supply voltage range of 2V to 5.5V for both analog and digital domains. Key performance parameters include a maximum data rate of 860 samples per second and an operating temperature range from -40°C to +125°C. The component is housed in a compact 10-VSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Automotive-grade reliability certified to AEC-Q100 standards for extended temperature operation
• Integrated signal conditioning chain featuring a programmable gain amplifier and multiplexer
• Low-power sigma-delta conversion architecture with internal reference capabilities
• Compact surface-mount packaging suitable for space-constrained automotive designs

Analog To Digital Converters (ADC) Applications

• Automotive sensor interface circuits requiring high-resolution data acquisition
• Battery management systems within electric or hybrid vehicles
• Body control modules and safety-critical monitoring subsystems

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific suffix QDGSRQ1 corresponds to the intended automotive grade and tape-and-reel packaging configuration. Confirm that the device meets the required AEC-Q100 reliability specifications for your target application environment. Ensure compatibility with existing I2C bus protocols and voltage levels during integration planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 16-bit resolution is required for automotive environments. Compare against the ADS1115 variant if four-channel input capability is necessary instead of two. Consider the ADS1114IDGSR for non-automotive industrial applications where AEC-Q100 certification is not mandatory but similar electrical characteristics are desired.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS111x-Q1 family of ultra-small, low-power ADCs. It shares architectural similarities with the ADS1113 and ADS1115 models, differing primarily in channel count and specific automotive qualification status. The 'Q1' designation indicates compliance with automotive quality standards, while the base ADS1114 identifier denotes the two-channel configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1115BQDGSRQ1 serves as a direct functional substitute offering identical electrical performance with additional input channels. For non-automotive replacements, the ADS1114IDGSR provides equivalent specifications without automotive certification.
