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.ROHM has developed ARMOUR-like operational amplifiers that are immune to external noise (ElectroMagnetic noise).
"EMARMOUR™" is ROHM's trademark that is given only to products that have realized noise tolerance that minimizes output voltage fluctuations in international noise evaluation tests.
Features
"EMARMOUR™" was developed by combining ROHM's "circuit design technology," "layout technology," and "process technology." This brand name is given only to products that achieve a noise tolerance of ±300mV or less. Overwhelming noise tolerance contributes to reducing design man-hours and increasing reliability by solving noise issues in system development.
