Frequently Asked Questions

What is the CMRR of the MC33078MDREPG4?

The MC33078MDREPG4 provides a typical common-mode rejection ratio of 100dB, with a minimum specified value of 80dB. This high CMRR ensures excellent rejection of common-mode interference signals, making the device appropriate for differential sensor amplification in electrically noisy industrial and measurement environments.

What is the input offset voltage and bias current of the MC33078MDREPG4?

The MC33078MDREPG4 has a maximum input offset voltage of 3000µV (3mV) and a maximum input bias current of 0.75µA at 25°C with an average of 0.8µA over the operating range. These parameters are critical for precision DC amplification and filter designs where accumulated offset errors must be minimized.

Does the MC33078MDREPG4 require external frequency compensation?

No, the MC33078MDREPG4 includes internal frequency compensation, eliminating the need for external compensation capacitors or resistor networks. This simplifies PCB design and reduces component count in signal processing circuits while ensuring stable operation across a wide range of closed-loop gain configurations.

What package does the MC33078MDREPG4 use and is it RoHS compliant?

The MC33078MDREPG4 is available in a surface-mount package (as indicated by the MDP suffix), and carries the G4 suffix confirming RoHS and REACH compliance with a lead-free material set. The PG4 designation ensures it meets current environmental regulations for consumer, industrial, and automotive electronics manufacturing.

What are typical applications for the MC33078MDREPG4?

This dual op-amp is widely used in audio preamplifiers, active bandpass and low-pass filters, instrumentation amplifiers, and sensor signal conditioning circuits. Its high CMRR and low noise make it suitable for professional audio mixing consoles, medical measurement front-ends, industrial data acquisition systems, and precision analog computation circuits.
