Texas Instruments · Operational Amplifier · SOIC-8
OPA355UA 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 | NC | unconnected | No internal connection. |
| 2 | IN- | input | Inverting input pin, accepts common-mode voltage from (V-) - 0.1 V to (V+) - 1.5 V. |
| 3 | IN+ | input | Noninverting input pin, accepts common-mode voltage from (V-) - 0.1 V to (V+) - 1.5 V. |
| 4 | V- | power_in | Negative power supply rail. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Output pin, supports continuous output current of ±60 mA. |
| 7 | V+ | power_in | Positive power supply, voltage differential from V- of 2.7 V to 5.5 V. |
| 8 | ENABLE | input | Digital enable input, low (0.8 V threshold) disables amplifier, high (2 V threshold) enables normal operation, pin must be driven. |
