Dual op-amp for automotive signal chains
The MC33078DT is a dual general-purpose operational amplifier qualified to AEC-Q100. It delivers a gain-bandwidth product of 15 MHz and a slew rate of 7 V/µs. The supply span runs from 5 V to 30 V. Input offset voltage is trimmed to 150 µV, and input bias current is 250 nA.
Temperature range and package fit
The operating temperature range is -40°C to 105°C. The part comes in an 8-SOIC package (3.90 mm body width), surface-mount only. The dual-channel configuration saves board space, and the 4 mA per-channel supply current keeps the thermal budget manageable.
Sourcing and lifecycle
The MC33078DT is listed as Active in production with ROHS3 compliance. There is no NRND or EOL notice. The AEC-Q100 qualification means this part is already approved for automotive production lines. If you are dual-sourcing, the MC33078YDT is the same die in a different packaging option (Digi-Reel®), and the MC33079YDT offers a quad-channel variant with a wider temperature range up to 125°C. The MC3303DT is a slower alternative (1 MHz GBW) and not a direct speed replacement.
