BA2902F
Standard Ground Sense Operational Amplifier

ROHM's general purpose BA10358 and BA10324A models, along with its BA2904 and BA2902 high reliability units, feature high gain and built-in phase compensation and integrate 2 or 4 circuits on a single chip. Additional features include a wide operating voltage range of 3V to 32V (single power supply use) and low current consumption, making them ideal for a broad number of applications. The BA3404 in particular delivers faster speeds while reducing crossover distortion compared with the BA10358 and BA2904 models.
