BUF634AIDR 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 | BW | input | Bandwidth adjustment input; connect to V- pin for wide-bandwidth mode (210 MHz) or leave floating for low-quiescent current mode (35 MHz). |
| 2 | NC | unconnected | No internal connection. |
| 3 | VIN | power_in | Signal input; accepts linear input voltage range of -13 V to +13 V at RL = 1 kΩ. |
| 4 | V- | power_in | Negative power supply; operating range ±2.25 V to ±18 V total supply voltage. |
| 5 | NC | unconnected | No internal connection. |
| 6 | VO | output | Output; delivers up to ±250 mA continuous output current with output voltage swing from 1.6 V to 2.5 V from supplies depending on output current. |
| 7 | V+ | power_in | Positive power supply; operating range ±2.25 V to ±18 V total supply voltage. |
| 8 | NC | unconnected | No internal connection. |
