Operational Amplifiers / Comparators Series

Operational amplifiers are general purpose ICs that incorporate phase compensation for use in analog and digital circuits requiring amplification (attenuation), such as buffer, integration, and differential circuits.
Comparators are ICs that allow arbitrary setting of the reference voltage and are indispensible components in current/voltage detection and protection circuits.
ROHM offers a full lineup of op-amps and comparators, including bipolar, CMOS, ground sense (single power supply), dual supply, high voltage resistance, low noise, low saturation, low current consumption, and input/output full swing types.
