PRELIMINARY INFORMATION EVALUATION KIT AVAILABLE TC1025 LINEAR BUILDING BLOCK – DUAL LOW POWER COMPARATOR 2 FEATURES GENERAL DESCRIPTION ■ ■ ■ The TC1025 is a dual, low power, complimentary output comparator designed specifically for low power applications. The TC1025 is designed for operation from a single supply, however, operation from dual supplies is also possible, and the power supply current drain is independent of the magnitude of the power supply voltage. Maximum supply current is 8µA and operation is guaranteed to VDD = 1.8V. The input and output signal swing is rail-to-rail. Packaged in a space-saving 8-pin MSOP, the TC1025 consumes half the board area required by a standard 8-pin SOIC package. It is ideal for applications requiring high integration, small size and low power. ■ ■ ■ Rail-to-Rail Inputs and Outputs Optimized for Single Supply Operation Small Package ...................................... 8-Pin MSOP (Consumes Half the Space of an 8-pin SOIC) Ultra Low Input Bias Current ......
