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

 Consumer electronics
