HT33078ARMZ

HTCSEMI · Operational Amplifier · MSOP-8

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.
