XTR116U from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VREF | power_in | Reference voltage output, 4.096V for XTR116 with maximum output current 16mA short-circuit rating. |
| 2 | IIN | input | Current input pin referenced to IRET with zero voltage point; input voltage range 0V to V+ via external resistor. |
| 3 | IRET | power_in | Local ground return reference for internal voltage regulators VREG and VREF; all return currents must flow through this pin. |
| 4 | IO | output | 4mA to 20mA regulated current loop output with internal current limit of 32mA maximum. |
| 5 | E | input | External NPN transistor emitter connection for implementing precision current source output stage. |
| 6 | B | output | External NPN transistor base connection driven by internal current source for output current regulation. |
| 7 | V+ | power_in | Loop power supply input; operating voltage range 7.5V to 36V with absolute maximum 40V. |
| 8 | VREG | power_out | 5V regulated voltage output for external circuitry with maximum output current 3mA and ±0.1V accuracy over -40°C to +85°C. |
