ADS1110A0IDBVT

Analog To Digital Converters (ADC) Overview

The ADS1110A0IDBVT is a 16-bit, single-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. The device features an internal 2.048V reference, providing a differential input range of ±2.048V. It supports configurable data rates of 15, 30, 60, or 240 samples per second. An onboard programmable gain amplifier (PGA) offers gains up to 8. The component utilizes an I2C-compatible serial interface and is housed in a compact SOT-23-6 package. It functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a precision internal voltage reference and programmable gain amplifier to support high-resolution measurements of small signals without external components.
• Features continuous self-calibration capabilities to maintain accuracy over time and operating conditions.
• Supports automatic power-down after each conversion in single-shot mode to minimize current consumption during idle periods.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instruments requiring low power and high resolution
• Industrial process control systems with limited board space
• Smart transmitters and sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDBVT confirms the tape-and-reel packaging format and the A0 grade designation. Confirm that the I2C address configuration matches the system requirements, as the A0 variant has a fixed default address. Ensure compatibility with the target microcontroller's I2C bus voltage levels and timing specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single-ended or differential input is required with a maximum sampling rate of 240 SPS. The internal reference eliminates the need for external precision references, simplifying the schematic. Consider the SOT-23-6 package constraints for thermal management if operating at the upper end of the temperature range or with higher gain settings.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1110 family of 16-bit delta-sigma ADCs. Variants such as ADS1110A1IDBVT or ADS1110A4IDBVT differ primarily in their I2C slave addresses or specific calibration offsets, while maintaining identical electrical performance characteristics and pinouts. The family is designed for applications prioritizing size and power efficiency.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1110A0IDBVR serves as a direct functional substitute with identical electrical specifications, differing only in the reel versus cut-tape packaging format. Other ADS1110 variants with different address suffixes may require software address adjustments but remain electrically compatible.
