ROHM's BA8290xYxxx-C series high-gain, ground-sense input op amps are monolithic ICs that integrate independent dual or quad op amps on a single chip. Models featuring low power consumption are offered and are operable from 3 V to 36 V (single-power-supply). High reliability supports automotive requirements making them ideal for ECUs, electric power-steering systems, and more.
