HT33078ARZ from HTCSEMI, in a SOP-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 | Output 1 | output | Output of amplifier 1, which uses an all-NPN output stage; the maximum ratings list output short-circuit duration as indefinite. |
| 2 | Inputs 1 (-) | input | Inverting input of amplifier 1; either or both input voltages must not exceed the magnitude of VCC or VEE (Note 1). |
| 3 | Inputs 1 (+) | input | Non-inverting input of amplifier 1; either or both input voltages must not exceed the magnitude of VCC or VEE (Note 1). |
| 4 | VEE | power_in | Negative supply rail; dual supply operation is stated as 5.0 V to 18 V, and the maximum supply voltage VCC to VEE is +36 V. |
| 5 | Inputs 2 (+) | input | Non-inverting input of amplifier 2; either or both input voltages must not exceed the magnitude of VCC or VEE (Note 1). |
| 6 | Inputs 2 (-) | input | Inverting input of amplifier 2; either or both input voltages must not exceed the magnitude of VCC or VEE (Note 1). |
| 7 | Output 2 | output | Output of amplifier 2, which uses an all-NPN output stage; the maximum ratings list output short-circuit duration as indefinite. |
| 8 | VCC | power_in | Positive supply rail; dual supply operation is stated as 5.0 V to 18 V, and the maximum supply voltage VCC to VEE is +36 V. |
