BA3472FVM
High Speed Ground Sense Operational Amplifier

General-purpose BA3472 / BA3474 family integrate two/four Independent Op-amps and phase compensation capacitors on a single chip and have some features of high-gain, low power consumption, and wide operating voltage range of +3[V] ~ +36[V](single power supply). Especially, characteristics are high slew rate (10V/µs) and high Maximum frequency (4MHz).
