ADS1110A2IDBVTG4

Analog To Digital Converters (ADC) Overview

The ADS1110A2IDBVTG4 is a 16-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It features an integrated internal reference voltage of 2.048 V and a programmable gain amplifier (PGA). The device supports I2C serial interface communication and operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital domains. It offers differential or single-ended input configurations with a maximum sampling rate of 128 samples per second. The component is housed in a compact SOT-23-6 package and is rated for industrial operating temperatures between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a precision internal reference voltage source to eliminate external component requirements.
• Includes a programmable gain amplifier to optimize signal range for low-level inputs.
• Utilizes sigma-delta modulation architecture for high-resolution data conversion.
• Supports standard I2C communication protocol for simplified system integration.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise sensor signal digitization.
• Portable battery-powered instrumentation due to low power consumption characteristics.
• Medical equipment applications needing high resolution in a small form factor.
• Data acquisition modules interfacing with thermocouples or RTDs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm availability status, as some variants within this family may be discontinued or subject to long lead times. Ensure the ordering part number matches the required pinout and temperature grade specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is required with minimal external circuitry. The internal reference and PGA reduce bill of materials count compared to ADCs requiring external references. Consider the I2C interface speed limitations if higher throughput than 128 SPS is needed. Verify that the SOT-23-6 package size fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1110 series of 16-bit ADCs designed for low-power, high-accuracy applications. It shares architectural similarities with other members like the ADS1110A0IDBVTG4 but differs in factory-set gain settings defined by the middle character in the part number. The 'G4' suffix typically denotes green/RoHS-compliant packaging options offered by Texas Instruments.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1110A2IDBVT is the non-green variant of the same functional device. ADS1110A0IDBVTG4 and ADS1110A4IDBVTG4 are alternative gain settings within the same package and interface family. Direct substitution requires verifying the PGA gain configuration matches the application signal levels.
