INA2137UA from Texas Instruments, in a SOIC-14. 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 | NC | unconnected | No connection; leave unconnected. |
| 2 | -In A | input | Inverting input for channel A; connected to negative side of differential input signal. |
| 3 | +In A | input | Non-inverting input for channel A; connected to positive side of differential input signal. |
| 4 | V- | power_in | Negative supply voltage terminal; rated for ±4V to ±18V supply range. |
| 5 | +In B | input | Non-inverting input for channel B; connected to positive side of differential input signal. |
| 6 | -In B | input | Inverting input for channel B; connected to negative side of differential input signal. |
| 7 | NC | unconnected | No connection; leave unconnected. |
| 8 | Ref B | input | Reference input for channel B for output offset voltage adjustment; source impedance should be <10Ω. |
| 9 | Out B | output | Output for channel B; voltage swing (V+)-2V to (V+)-1.8V positive or (V-)+2V to (V-)+1.6V negative. |
| 10 | Sense B | output | Sense output for channel B; provides access to feedback network resistor tap point. |
| 11 | V+ | power_in | Positive supply voltage terminal; rated for ±4V to ±18V supply range. |
| 12 | Sense A | output | Sense output for channel A; provides access to feedback network resistor tap point. |
| 13 | Out A | output | Output for channel A; voltage swing (V+)-2V to (V+)-1.8V positive or (V-)+2V to (V-)+1.6V negative. |
| 14 | Ref A | input | Reference input for channel A for output offset voltage adjustment; source impedance should be <10Ω. |
