No.11049EBT23
●Description
Automotive series BA2904Y family and BA2902Y family
integrate two or four independent Op-Amps and phase
compensation capacitors on a single chip and have
some features of high-gain, low power consumption, and
operating voltage range of 3[V] to 32[V] (single power
supply ).
●Features
1) Operable with a single power supply
2) Wide operating supply voltage
+3.0[V]½+32.0[V]( single supply)
3) Standard Op-Amp Pin-assignments
4) Input and output are operable GND sense
5) Internal phase compensation type
6) Low supply current
7) High open loop voltage gain
8) Internal ESD protection
Human body model (HBM)
±5000[V](Typ.)
9) Wide temperature range
-40[℃]½+125[℃]

Note: Absolute maximum rating item indicates the condition which must not be exceeded.
Application if voltage in excess of absolute maximum rating or use out of absolute maximum rated temperature
environment may cause deterioration of characteristics.
(*1) 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.

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.
