Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OA1 | passive | Offset adjustment (失调调整) terminal for nulling the input offset voltage; the datasheet gives no limits for this pin. |
| 2 | IN- | input | Inverting input of the amplifier. |
| 3 | IN+ | input | Non-inverting input of the amplifier. |
| 4 | V- | power_in | Negative power supply terminal; recommended supply is ±15V with absolute maximum supply of ±18V. |
| 5 | OA2 | passive | Offset adjustment (失调调整) terminal for nulling the input offset voltage; the datasheet gives no limits for this pin. |
| 6 | OUT | output | Amplifier output; the datasheet specifies output swing of -14V to +12V at RL=2kΩ. |
| 7 | V+ | power_in | Positive power supply terminal; recommended supply is ±15V with absolute maximum supply of ±18V. |
| 8 | ST | input | Strobe (选通) pin; the datasheet names the function but gives no logic levels, timing, or limits for it. |
