DIO2333B is an ultra low VOS operational amplifier, with rail-to-rail CMOS input/output and single/dual channels selectable. DIO2333B has a gain-bandwidth product of 30kHz(typ.), wide operating supply voltage from 1.8V to 5.5V and broad output voltage swing. DIO2333B consumes ultra low power, with each channel 1.0μA(typ.) of bias current, which makes DIO2333B be ideal for battery powered device, temperature-sense device, etc.
