What are the key features of XTR112UAE4?
- 4-20 mA two-wire current loop output with 36 V supply tolerance for industrial sensor transmitter designs
- On-chip sensor excitation and signal conditioning eliminating external precision resistors in bridge and RTD interfaces
- 14-pin SOIC package with programmable span and zero adjustment enabling single-chip 4-20 mA transmitter implementation
What is XTR112UAE4 used for?
The XTR112 is designed for industrial process control where sensor signals from RTDs, thermistors, or resistive bridge sensors must be transmitted over 4-20 mA current loops across distances up to several hundred meters without signal degradation. It integrates sensor excitation and linearization in a single 14-pin SOIC, simplifying the design of smart transmitters for pressure, temperature, and flow measurement modules. The 36 V supply rating ensures compatibility with standard 24 V loop-powered field instrument installations.

Frequently Asked Questions
How does the XTR112UAE4 simplify connecting a resistive bridge sensor to a 4-20 mA industrial loop?
The XTR112 integrates a precision voltage reference and instrumentation amplifier input, allowing a Wheatstone bridge sensor with 100 Ω to 1 kΩ arms to connect directly to the device inputs. The chip converts the differential bridge output to a proportional 4-20 mA loop current accurate to within 0.05%, eliminating the need for separate op-amp gain stages and precision resistor networks typical in discrete transmitter designs.
What is the maximum supply voltage of the XTR112UAE4 and how does this relate to standard 24 V loop-powered installations?
The XTR112UAE4 supports a maximum supply voltage of 36 V, comfortably exceeding the 24 V nominal supply used in standard industrial 4-20 mA current loops. The 12 V margin accommodates cable voltage drop and supply regulation tolerance in field instrument wiring runs up to 300 meters, ensuring the device remains within its safe operating area under worst-case line conditions in process plant installations.
Can the XTR112UAE4 be used in two-wire loop-powered configurations, and what minimum loop voltage is needed?
Yes, the XTR112UAE4 is designed for two-wire loop-powered transmitter configurations where the same 2 wires carry both the 4-20 mA signal current and supply power. The device requires a minimum loop compliance voltage of approximately 7.5 V across its supply pins to maintain regulation, meaning a 24 V source with up to 16.5 V of cable and load resistance drop still leaves sufficient headroom for accurate 4-20 mA output at full 20 mA span.
