Single and dual comparators form Fairchild Semiconductor consume <10 micro Amps

Fairchild Semiconductor has developed the FAN156 low voltage comparator and the FAN256 dual low voltage comparator to provide supply chain flexibility.

By having both single and dual low voltage comparator options, the solution provided the customer the flexibility they needed by offering the option to use one or the other - or both - depending on the application requirements. In addition, it simplified their supply chain management having both solutions available from one source.

The FAN156 and FAN256 are low power comparators that typically consume less than 10µA of supply current, operate at a low voltage of 1.6V and are fully operational up to 5.5V, making them suitable for use in 1.8V, 3.0V and 5.0V systems, explains Fairchild. These comparators are used for applications including mobile phones, alarm and security systems, personal digital assistants, computers and portable medical devices.

In mobile applications, the FAN156 and FAN256 help to reduce the 3-times falling issue associated with slow insertion of an audio headset jack, as well as enable different audio headset jacks to be used in the same device. Both devices feature a complementary push-pull P- and N-channel output stage capable of driving a rail-to-rail output swing with a load ranging up to 5.0mA.
