ADS1110A3IDBVRG4

Analog To Digital Converters (ADC) Overview

The ADS1110A3IDBVRG4 is a precision, continuous self-calibrating analog-to-digital converter (ADC) from Texas Instruments. It features a 16-bit Sigma-Delta architecture with a single differential or single-ended input channel. The device integrates an internal 2.048V voltage reference and a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and communicates via an I2C-compatible serial interface. Available in a compact SOT-23-6 package, it supports data rates of 15, 30, 60, or 240 samples per second.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the operating temperature range is -40°C to +125°C for the industrial grade variant. Check current availability status as distribution channels may list this component as obsolete or active depending on the region.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high accuracy is required in space-constrained designs. The internal reference eliminates the need for external components, reducing board size. Ensure the I2C bus speed matches the system requirements, as the device supports standard and fast modes. Consider the PGA setting to optimize the input range for the specific signal amplitude.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1110 family of ultra-small, low-power ADCs. It shares architectural similarities with the ADS1100 but includes an internal oscillator and voltage reference. The 'A3' designation typically specifies the default I2C address configuration within the series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1110A3IDBVT is a pin-compatible alternative in a different package type. Verify that any substitute maintains the same I2C addressing and PGA functionality.
