OPA301AIDR
Texas Instruments · Operational Amplifier · SOIC-8
OPA301AIDR 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 on the OPA301 SO-8 package; the datasheet footnote (1) that qualifies NC is not present in the extracted text. |
| 2 | -In | input | Inverting amplifier input; signal inputs are clamped to the supply rails by ESD diodes, and input current must be limited to 10 mA when a signal exceeds a rail by more than 0.5 V. |
| 3 | +In | input | Non-inverting amplifier input; signal inputs are clamped to the supply rails by ESD diodes, and input current must be limited to 10 mA when a signal exceeds a rail by more than 0.5 V. |
| 4 | V- | power_in | Negative supply voltage; the device is specified for a total supply of 2.7 V to 5.5 V between V+ and V-. |
| 5 | NC | unconnected | No internal connection on the OPA301 SO-8 package; the datasheet footnote (1) that qualifies NC is not present in the extracted text. |
| 6 | VOUT | output | Amplifier output, which swings to within about 100 mV of each supply rail with a 2 kΩ load, and whose short-circuit duration is continuous per the absolute maximum ratings. |
| 7 | V+ | power_in | Positive supply voltage; the device is specified for 2.7 V to 5.5 V with an absolute maximum of 7 V. |
| 8 | NC | unconnected | No internal connection on the OPA301 SO-8 package; the Enable function is only on the OPA300 variant. |
