Texas Instruments · Operational Amplifier · SOT-23-5
OPA137NA from Texas Instruments, in a SOT-23-5. 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 | OUT | output | Output of the operational amplifier, swings to (V-)+1.2V minimum and (V+)-1.1V maximum into a 10k ohm load. |
| 2 | V- | power_in | Negative supply pin; operates from -2.25V to -18V in dual-supply configuration or ground in single-supply configuration. |
| 3 | +IN | input | Non-inverting input of the operational amplifier, part of a FET input stage with input bias current of about ±10pA. |
| 4 | -IN | input | Inverting input of the operational amplifier, part of a FET input stage with input bias current of about ±10pA. |
| 5 | V+ | power_in | Positive supply pin; operates from +2.25V to +18V in dual-supply configuration or up to +36V in single-supply configuration. |
