MC33074ADG

MC33074ADG Description

The MC33074ADG from onsemi is a quad general-purpose operational amplifier (op-amp) housed in a 14-SOIC package. Designed for versatility, it operates over a wide supply voltage range of 3V to 44V, making it suitable for both low-voltage and high-voltage applications. With a slew rate of 13V/µs and a gain bandwidth product of 4.5 MHz, it delivers robust performance for signal conditioning, filtering, and amplification tasks. The device features low input bias current (100 nA) and moderate input offset voltage (500 µV), ensuring precision in DC-coupled circuits. Its 30 mA output current per channel enables driving moderate loads, while the 1.9mA supply current per amplifier ensures efficient power consumption.
