DIO20381 is an ultra low power operational amplifier, with rail-to-rail CMOS input/output and single/dual channels selectable. DIO20381 has a gain-bandwidth product of 5kHz, wide operating supply voltage from 1.4V to 5.5V and broad output voltage swing. DIO20381 consumes ultra low power, with each channel 380nA of bias current, which makes DIO20381 be ideal for battery powered device, temperature-sense device, etc. The DIO20381 operational amplifier family is available in single configuration. Furthermore, the DIO20381 is offered in the 5-lead SOT23 package. It is fully specified over the extended -40°C to +125°C temperature range.
