ELM842B CMOS Low power operational amplifier
■General description
ELM842B is low voltage and low power CMOS single operational amplifier which makes it easy to design
circuits and operates from a 1.2V single power source. As for power supply voltage, ELM recommends to use
within the range of 1 . 2 V to 5 . 5 V. The consumption current of ELM842B is low; on the other hand, since the
output stage of ELM842B is class A operation drive, ELM842B is able to provide current supply of 90μA(Typ.
At Vdd=1.5V). ELM842B is suitable for signal process of applications which require low power.

* When power supply voltage is below 5.0V, short of output terminal will do no damage to the IC.
When power supply voltage is above 5.0V, it may cause short of VDD and result in reliability damage of the IC.
