AP393 Low Power Low Offset Voltage Dual Comparators „ Features - Wide supply Voltage range: 2.0V to 36V Single or dual supplies: ±1.0V to ±18V - Very low supply current drain (0.4 mA) – independent of supply voltage - Low input biasing current: 25 nA - Low input offset current: ±5 nA - Maximum offset voltage: ±3 mV - Input common-mode voltage range includes ground - Differential input voltage range equal to the power supply voltage - Low output saturation voltage: 250 mV at 4 mA - Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems - 8-pin PDIP and SOP Pb-Free packages „ General Description The AP393 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The AP393 is designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the AP393 will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. „ Advantages - High precision comparators - Reduced VOS drift over temperature - Eliminates need for dual supplies - Allows sensing near ground - Compatible with all forms of logic - Power drain suitable for battery operation „ Pin Assignment (Top View) OUTPUT 1 1 INVERTING INPUT 1 2 NON-INVERTING INPUT 1 3 GND 4 8 AP393 7 6 5 V+ OUTPUT 2 INVERTING INPUT 2 NON-INVERTING INPUT 2 SOP-8L/PDIP-8L „ Pin Descriptions Pin Name OUTPUT 1 INVERTING INPUT 1 NON-INVERT ING INPUT 1 GND Pin No. 1 2 3 4 Description Channel 1 Output Channel 1 Negative Input Channel 1 Positive Input Ground Pin Name NON-INVERT ING INPUT 2 INVERTING INPUT 2 OUTPUT 2 + V Pin No. 5 6 7 8 Description Channel 2 Positive Input Channel 2 Negative Input Channel 2 Output Vcc This datasheet contains new product information.
