Overview
ROHM's op amps come in bipolar and CMOS types, and offer a wide range of products that are ideal for applications such as single power supply, dual power supply, high withstand voltage, low noise, low saturation, low current consumption, and input/output full swing.
We will pursue op amps that "do not emit noise" and "do not receive noise" by differentiating them in terms of noise characteristics.
