DIO20881 is an ultra low power operational amplifier, with rail-to-rail CMOS input/output and single/dual channels selectable. DIO20881 has a gain-bandwidth product of 14kHz, wide operating supply voltage from 1.4V to 5.5V and broad output voltage swing. DIO20881 consumes ultra low power, with each channel 600nA of bias current, which makes DIO20881 be ideal for battery powered device, temperature-sense device, etc. The DIO20881 operational amplifier is available in single configuration. Furthermore, the DIO20881 is offered in the 5-lead SOT23 package. It is fully specified over the extended -40°C to 125°C temperature range.
