BA3472xxx BA3472RFVM BA3474xxx BA3474RFV
General Description
BA3472xxx/BA3472RFVM/BA3474xxx/BA3474RFV
are high speed operational amplifiers of dual circuits
and quad circuits. An operational range is wide with
+3V~+36V (single power supply), and gain bandwidth
product 4MHz and a high slew rate of in wideband and
10V/μs are good points.
Features
Operable with a single power supply
Wide operating supply voltage
Internal phase compensation
High open loop voltage gain
Operable low input voltage around GND level
Wide output voltage range
Application
Current sense application
Buffer application amplifier
Active filter
