XTR106UA from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VREG | power_out | 5.1V regulator output. Provides regulated supply for external circuitry powered from the loop. |
| 2 | VIN- | input | Negative (inverting) differential voltage input to the instrumentation amplifier front end. |
| 3 | RG | passive | Input-stage gain-setting pin. External resistor RG between pins 3 and 4 sets the voltage-to-current transfer gain (S = 40 / RG A/V). |
| 4 | RG | passive | Input-stage gain-setting pin. External resistor RG between pins 3 and 4 sets the voltage-to-current transfer gain. |
| 5 | VIN+ | input | Positive (non-inverting) differential voltage input to the instrumentation amplifier front end. |
| 6 | IRET | input | Local ground return pin for VREG, VREF5, and VREF2.5. Sinks the reference/regulator quiescent currents back through the loop. |
| 7 | IO | output | Regulated 4mA to 20mA current-loop output. Drives the external NPN pass transistor via B/E to modulate loop current. |
| 8 | E | input | Emitter connection for the external NPN pass transistor (e.g., TIP29C) used in the loop current output stage. |
| 9 | B | output | Base drive for the external NPN pass transistor in the loop current output stage. |
| 10 | V+ | power_in | Loop supply input. Operating range 7.5V to 36V (absolute maximum 40V), referenced to the IO pin. |
| 11 | RLIN | passive | Linearization resistor pin. External resistor between pins 1 (VREG) and 11 sets the correction coefficient of the bridge linearization circuit. |
| 12 | Lin Polarity | input | Linearization polarity select. Tie to IRET for positive-going nonlinearity correction, or to VREG for negative-going correction / linearization disabled. |
| 13 | VREF2.5 | power_out | 2.5V precision reference / bridge excitation output. |
| 14 | VREF5 | power_out | 5V precision reference / bridge excitation output. |
