ELM832BW CMOS Low power dual operational amplifier
■General description
ELM832BW is low power CMOS dual operational amplifier which consists of doubly-packed ELM832B.
ELM832BW makes it easy to design power circuits and is able to operate from single +1.2V source.
■Features
• Operation from a single power source
• Low voltage operation : 1.2V≤Vdd≤6.0V
• Low current consumption
: 50μA(Typ. Vdd=3.0V, 2Amp. units total)
• Common-mode input voltage range
: Vss to Vdd-0.3V (Vdd=1.5V)
: Vss to Vdd-0.1V (Vdd=3.0V)
• Output stage
: Push-pull
• Unity gain bandwidth : Typ. 200kHz
• Package
: TSSOP-8
■Application
• Battery-operated portable devices
• Micropower signal process
• Low voltage analog circuit
■Maximum absolute ratings
