- Precision voltage-to-current conversion enables accurate 4 mA to 20 mA industrial loop transmitter output with less than 0.05% linearity error
- 10-pin MSOP/SOT-23 compatible package with exposed thermal pad reduces board area while supporting 260°C peak reflow soldering
- High output compliance voltage supports 4–20 mA loop operation over long cable runs with up to 500 Ω loop resistance
Applications
XTR111AIDRCTG4 is used as a 4 mA to 20 mA current loop transmitter in industrial process control, temperature sensing, and pressure measurement systems where signals must travel over long distances with high noise immunity. It converts low-voltage analog sensor outputs to current loop signals compatible with standard PLC analog input modules and DCS field devices. The compact 10-pin package also fits two-wire transmitter designs in flow meters and level sensors requiring isolated loop-powered operation.

Frequently Asked Questions
What output current range does XTR111AIDRCTG4 produce for industrial process control loops?
XTR111AIDRCTG4 generates a 4 mA to 20 mA output current proportional to a reference input voltage, covering the full industrial standard range used in 4–20 mA process control loops. This range corresponds to 0% to 100% of the measured variable, with the 4 mA live-zero enabling cable break detection when loop current falls below 3.5 mA.
How much loop resistance can XTR111AIDRCTG4 drive for long-cable industrial sensor installations?
XTR111AIDRCTG4 supports loop resistance up to 500 Ω at a 24 V loop supply, allowing cable lengths exceeding 300 m using standard 22 AWG twisted pair wire with 60 mΩ/m resistance per conductor. This covers most field instrument installations in chemical plants and water treatment facilities without requiring active cable compensation.
Which precision specification distinguishes XTR111AIDRCTG4 from lower-cost V-to-I converters?
XTR111AIDRCTG4 achieves less than 0.05% linearity error across the 4 mA to 20 mA output range, which corresponds to under 8 µA of error on a 16 mA span. This precision matches 12-bit ADC resolution requirements in smart transmitters, whereas lower-cost alternatives typically exhibit 0.1% to 0.5% linearity error that limits effective resolution to 8 to 10 bits.
Can XTR111AIDRCTG4 operate in two-wire loop-powered transmitter configurations?
XTR111AIDRCTG4 supports two-wire loop-powered configurations where all transmitter circuitry is powered from the same 4–20 mA loop current. With a quiescent supply current under 4 mA, the device leaves sufficient current headroom for signal conditioning electronics, making it compatible with HART-capable smart transmitter designs operating on a single 24 V two-wire loop.
