ADS1115BQDGSRQ1

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS1115BQDGSRQ1 is a 16-bit analog-to-digital converter (ADC) designed for automotive applications. It features an internal programmable gain amplifier, a multiplexer, and a comparator within a compact 10-VSSOP package. The device supports I2C communication and operates on a single power supply ranging from 2V to 5.5V. It offers configurable data rates up to 860 samples per second and accepts differential or single-ended inputs. The component is qualified under the AEC-Q100 standard and functions reliably across an industrial temperature range of -40°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-resolution 16-bit conversion is required for automotive sensor interfaces. Consider the integrated PGA for amplifying low-level signals without external op-amps. Evaluate the I2C address configuration needs if multiple devices share the same bus in the target design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS111x family of precision ADCs from Texas Instruments. It shares architectural similarities with non-automotive variants but includes enhanced durability specifications. The 'BQ' prefix typically denotes automotive qualification, while 'DGSR' indicates the specific VSSOP package and reel quantity.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other AEC-Q100 qualified 16-bit ADCs from Texas Instruments such as the ADS1114 or ADS1119, provided pinout and register compatibility are verified. Non-TI equivalents require careful evaluation of I2C timing and PGA performance.
