Comparators consume less than 10 µA

Comparators consume less than 10 µA

Ideal for applications including mobile phones, alarm and security systems, personal digital assistants, computers, and portable medical devices, the single FAN156 and dual FAN256 comparators typically consume less than 10 µA of supply current. They are guaranteed to operate at a low voltage of 1.6 V and are fully operational up to 5.5 V, making them ideal for use in 1.8-, 3.0-, and 5.0-V systems.

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 5.0 mA. The FAN156 is packaged in 6-lead, 1.0 x 1.45-mm MicroPak package, while the FAN256 is packaged in an 8-lead, 1.6 x 1.6-mm MicroPak package. (FAN156, $0.12; FAN256, $0.18 — samples available now.)
