General Description

The COMLINEAR CLC2550 (dual) and CLC4550 (quad) are precision voltage

comparators with a typical offset of 2mV and high gain (200V/mV). These

comparators also offer an input common-mode voltage range that includes

ground.

The COMLINEAR CLC2550, and CLC4550 operate from a wide supply voltage

range of ±1V to ±18V, or from a single supply range of 2V to 36V. These

comparators are available in Pb-free, RoHS compliant SOIC-8 and SOIC-14

packages. They operate over the industrial temperature range of -40°C to

+85°C.
