NJU7109 LOW POWER SUPER SMALL-SIZED SINGLE C-MOS COMPARATOR ■GENERAL DESCRIPTION The NJU7109 is super small-sized package single C-MOS comparator with push pull output. The operating voltage is from 1.8V to 5.5V, and the interface can be connected with most of TTL and C-MOS type standard logic ICs. Furthermore, The input offset voltage is lower than 7mV and the package is super small-sized SC88A, therefore they can be suitable for battery use items and other portable items. ■PACKAGE INFORMATION ■FEATURES ●Single Low Power Supply ●Low Offset Voltage ●Low Operating Current ●Push Pull Output ●Package Outline ●C-MOS Technology ■PIN CONFIGURATION (Top View) VDD=1.8~5.5V VIO=7mV max IDD=100µA SC88A NJU7109F3 IN- 1 5 VDD VSS 2 IN+ 3 4 OUT ■EQUIVALENT CIRCUIT VDD INOUT IN+ VSS (1) NJU7109 ■ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER SYMBOL RATING UNIT Supply Voltage VDD 7.0 V Differential Input Voltage VID V ±7.0 (Note1) Common Mode Input Voltage VIC -0.3~7.0 V Power Dissipation PD 250 (Note2) mW Operating Temperature Topr -40~+85 °C Storage Temperature Tstg -55~+125 °C Note1) If the supply voltage (VDD) is less than 7.0V, the input voltage must not over the VDD level though 7.0V is limit specified. Note2) The power dissipation is value mounted on aglass epoxy board (FR-4) in size of 50x50x1.6 millimeters square. Note3) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit. ■RECOMMENDED OPERATING CONDITION PARAMETER Operating Voltage (VDD=3.0V,Ta=25°C) MAX UNIT 5.5 V SYMBOL VDD CONDITIONS MIN 1.8 TYP -
