THEORY OF OPERATION

Lower Supply Current for 1MHz Gain Bandwidth

The MAX74822 typically uses 45µA of current per amplifier, which is much less than the 200µA to 700µA used in

earlier generation parts with similar performance. This makes the MAX74822 a good choice for upgrading portable

designs for longer battery life. Alternatively, additional functions and performance can be added at the same

current drain.

Higher Output Current

At 5V single supply, the short-circuit current is typically 60mA. Even 1V from the supply rail, the MAX74822 amplifier

can provide a 30mA output current, sourcing, or sinking.
