●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

Note Absolute maximum rating item indicates the condition which must not be exceeded.
Application of voltage in excess of absolute maximum rating or use out absolute maximum rated temperature environment may cause
deterioration of characteristics.
*1
To use at temperature above Ta＝25℃ reduce 8.6mW/℃.
*2
To use at temperature above Ta＝25℃ reduce 6.7mW/℃.
*3
To use at temperature above Ta＝25℃ reduce 6.0mW/℃.
*4
To use at temperature above Ta＝25℃ reduce 10.8mW/℃.
*5
Mounted on a FR4 glass epoxy 4 layers PCB 70mm×70mm×1.6mm (occupied copper area: 70mm×70mm).
*6
The voltage difference between inverting input and non-inverting input is the differential input voltage.
Then input terminal voltage is set to more than VEE.

Absolute value
Current direction: Since first input stage is composed with PNP transistor, input bias current flows out of IC.
Under high temperatures, please consider the power dissipation when selecting the output current.
When the output terminal is continuously shorted the output current reduces the internal temperature by flushing.
