LMH6646MA/NOPB General Description

Despite its low supply current of 650 µA per amplifier, the LMH6646MA/NOPB can handle output currents up to ±20 mA, allowing it to drive heavier loads without sacrificing performance. Moreover, key parameters such as bandwidth, slew rate, and output current remain stable regardless of the operating supply voltage, thanks to advanced design features. In portable applications, the LMH6647 model offers shutdown capability with minimal turn-off current, making it an efficient choice for power-saving and multiplexing applications
