Single and Dual Comparators

Fairchild Semiconductor developed the FAN156 low voltage comparator and the FAN256 dual low voltage comparator to provide system design flexibility. The FAN156 and FAN256 are low power comparators that typically consume less than 10µA of supply current. They are guaranteed to operate at a low voltage of 1.6V and are fully operational up to 5.5V, making them ideal for use in 1.8V, 3.0V and 5.0V systems. These comparators are ideal 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 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.

The FAN156 is packaged in 6-lead, 1.0 x 1.45mm MicroPak™ package, while the FAN256 is packaged in an 8-lead, 1.6 x 1.6mm MicroPak package.
