| PRELIMINARY INFORMATION EVALUATION KIT AVAILABLE 1 TC1027 LINEAR BUILDING BLOCK - QUAD LOW POWER COMPARATOR AND VOLTAGE REFERENCE FEATURES s s s s s s s Combines Four Comparators and a Voltage Reference into a Single Package Optimized for Single Supply Operation Small Package ................. 16-Pin SOIC (Narrow) or 16-Pin Plastic DIP (Narrow) Ultra Low Input Bias Current ...... Less than 100pA Low Quiescent Current ........................... 15A max Rail-to-Rail Inputs and Outputs Operates Down to VDD = 1.8V min. 2 3 4 5 6 7 GENERAL DESCRIPTION The TC1027 is a mixed-function device combining four general purpose, complimentary output comparators and a voltage reference in a single 16-pin package. This increased integration allows the user to replace two packages, saving space, lowering supply current, and increasing system performance. The TC1027 is designed specifically for operation from a single supply; however, operation from dual supplies is also possible. The power supply current drain is independent of the magnitude of the power supply voltage. The TC1027 is optimized for low supply voltage and very low supply current operation (15A max) making it ideal for battery operated applications. Packaged in a 16-pin QSOP, SOIC (0.150 wide) or 16pin DIP, the TC1027 is ideal for applications requiring high integration, small size and low power.
