Product Overview
XTR111AIDGQR converts an input voltage into a precision industrial current output using one RSET resistor and an external P-channel MOSFET. The external transistor moves most loop/output power dissipation out of the IC and allows a broad compliance range.
DGQR is the 2500-piece large-reel version of the 10-pin HVSSOP package. It has the same electrical core as DGQT, but the reel quantity is different; procurement systems should retain the full suffix even though PCB footprint/function are shared.
The adjustable 3–15 V regulator can power nearby signal-conditioning circuitry, while EF and OD provide loop-fault visibility and output control. Those system pins make XTR111 more than a simple op-amp current source.

Functional Highlights
External PMOS choice sets compliance and thermal margin
The transistor’s VDS, power dissipation and safe operating area must cover worst-case supply/load/current conditions; choosing RSET alone does not complete the output-stage design.
DGQR versus DGQT is a packing decision, not a signal-chain redesign
Both use the DGQ footprint; DGQR supplies 2500 per large reel while DGQT is the 250-piece small reel. This distinction matters to production purchasing, not board electrical behavior.
Design Considerations
- Size the external PMOS for worst-case voltage drop and current with thermal margin.
- Choose RSET tolerance/tempco from required loop accuracy.
- Budget regulator load current and output compliance together so auxiliary circuitry does not compromise current-output range.
