ADS1110A3IDBVT

Analog To Digital Converters (ADC) Overview

The ADS1110A3IDBVT is a 16-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It features a single differential or single-ended input channel and operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. The device integrates an internal voltage reference and a programmable gain amplifier (PGA). It communicates via an I2C-compatible serial interface. Key electrical parameters include a resolution of 16 bits, a maximum sampling rate of 240 samples per second, and an operating temperature range of -40°C to +125°C. The component is housed in a compact SOT-23-6 surface-mount package.

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 a continuous self-calibration mechanism that minimizes offset and gain errors over time and temperature variations.
• Supports multiple data rates including 15, 30, 60, and 240 samples per second to optimize power consumption versus speed.
• Operates in a single-conversion mode where the device automatically powers down after each conversion to reduce idle current consumption.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instruments requiring low power and high accuracy.
• Industrial process control systems with I2C connectivity.
• Smart transmitters and sensor interfaces in harsh environments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A3' against the official datasheet to confirm the default data rate setting, as this variant typically corresponds to a fixed lower sampling rate compared to other ADS1110 models. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference the manufacturer's latest documentation for any pinout or marking changes before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS1110A3IDBVT when a fixed, lower sampling rate is acceptable to minimize power consumption in always-on applications. Compare it against the ADS1110A0IDBVT if a higher maximum data rate of 240 SPS is required. Consider the SOT-23-6 package constraints for thermal management and PCB space. Verify that the I2C address configuration meets the system bus requirements, as this model supports optional addressing.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1110 family of 16-bit delta-sigma ADCs designed for space-constrained and low-power applications. It shares core architectural similarities with the ADS1100 but offers extended industrial temperature ratings and integrated calibration features. The A3 suffix distinguishes its default operational characteristics within the broader ADS1110 product line.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1110A0IDBVT: Offers similar functionality but may differ in default data rate settings. ADS1110A1IDBVT: Alternative variant within the same series with potentially different factory-set parameters. Verify electrical compatibility and software register configurations before substitution.
