●General Description
BA3472Y, BA3474Y, BA3472W, and BA3474W
integrate two or four independent Op-amps on a
single chip. These Op-Amps can operate from
+3V to +36V (single power supply) with a high
slew rate (10V/μs) and high-gain bandwidth
(4MHz) characteristics.
●Features
 Single or dual power supply operation
 Wide operating supply voltage
 Standard Op-Amp Pin-assignments
 High open-loop voltage gain
 Internal ESD protection circuit
 Common-mode Input Voltage Range includes
ground level, allowing direct ground sensing
 Wide output voltage range
 AEC-Q100 Qualified
●Key Specifications
