Overview
The XTR111AIDGQTG4 is a precision voltage-to-current converter and transmitter manufactured by Texas Instruments. It operates within a supply voltage range of 7V to 44V, with a typical quiescent current of 450µA. The device accepts an input voltage from 0V to 12V and provides a proportional output current up to 25mA. It features a built-in 15V sub-regulator for powering external sensors. The component is housed in a 10-pin PowerPAD-MSOP package and supports operation across an extended temperature range of -55°C to 125°C.
Feature Summary
- Integrated 15V sub-regulator for sensor excitation
- High-precision voltage-to-current conversion capability
- Low power consumption suitable for battery-operated systems
Applications
- Industrial process control loop transmitters
- Pressure and temperature sensor signal conditioning
- 4-20mA current loop interface circuits
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm compliance status and pinout compatibility. Ensure the ordering information matches the exact package type and thermal pad requirements specified in the official datasheet before finalizing procurement.
Selection Notes
Select this component when high accuracy is required for converting low-level sensor voltages into standardized current signals. Consider the integrated regulator if the application requires powering the upstream sensor directly from the transmitter supply rail without additional discrete components.
Part Context
This part belongs to the XTR111 series of precision transmitters. It serves as a specialized interface solution for connecting analog sensors to industrial communication networks. The device simplifies design by combining amplification, regulation, and transmission functions into a single integrated circuit.
