HT33078ARMZ from HTCSEMI, in a MSOP-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 swings to approximately +14.1 V / −14.6 V with ±15 V supplies at RL = 2.0 kΩ. |
| 2 | Inputs 1 (-) | input | Inverting input of amplifier 1; the input voltage must not exceed the magnitude of VCC or VEE. |
| 3 | Inputs 1 (+) | input | Non-inverting input of amplifier 1; the input voltage must not exceed the magnitude of VCC or VEE. |
| 4 | VEE | power_in | Negative supply rail, with dual supply operation from 5.0 V to 18 V and the supply voltage (VCC to VEE) limited to +36 V maximum. |
| 5 | Inputs 2 (+) | input | Non-inverting input of amplifier 2; the input voltage must not exceed the magnitude of VCC or VEE. |
| 6 | Inputs 2 (-) | input | Inverting input of amplifier 2; the input voltage must not exceed the magnitude of VCC or VEE. |
| 7 | Output 2 | output | Output of amplifier 2, which swings to approximately +14.1 V / −14.6 V with ±15 V supplies at RL = 2.0 kΩ. |
| 8 | VCC | power_in | Positive supply rail, with the supply voltage (VCC to VEE) limited to +36 V maximum. |
