OPA847IDR from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection; may be left floating. |
| 2 | Inverting Input | input | Inverting input of the op amp; differential input voltage is limited to ±1.2V and the input voltage range is ±VS per Absolute Maximum Ratings. |
| 3 | Noninverting Input | input | Noninverting input of the op amp; common-mode input range (CMIR) is typically ±3.3V and the input voltage range is ±VS per Absolute Maximum Ratings. |
| 4 | -VS | power_in | Negative power supply pin; specified operating voltage is ±5V with a maximum operating voltage of ±6V. |
| 5 | NC | unconnected | No internal connection; may be left floating. |
| 6 | Output | output | Amplifier output pin; output voltage swing is ±3.5V min into a ≥400Ω load and ±3.4V min into a 100Ω load. |
| 7 | +VS | power_in | Positive power supply pin; specified operating voltage is ±5V with a maximum operating voltage of ±6V. |
| 8 | DIS | input | Power-down/shutdown control pin referenced to +VS; pulling this pin low (≤1.8V max off voltage) disables the amplifier, reducing supply current to <1% of powered-up value, while ≥3.5V min (or floating) enables normal operation. |
