●General Description
General-purpose BA3472,BA3472R,BA3474,BA3474R
integrate two/four Independent Op-amps and phase
compensation capacitors on a single chip and have some
features of high-gain, and wide operating voltage range of
+3[V] to +36[V](single power supply). Especially,
characteristics are high slew rate (10[V/μs]) and high
Maximum frequency (4[MHz]).
●Features
 Operable with a single power supply
 Wide operating supply voltage
 Standard Op-Amp. Pin-assignments
 Internal phase compensation
 High open loop voltage gain
 Internal ESD protection
 Operable low input voltage around GND level
 Wide output voltage range
