AP393A 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 (0.4mA) – independent of supply voltage Low input biasing current: 150nA Low input offset current: ±70nA Low input offset voltage: ±4mV Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage Low output saturation voltage: 250mV at 4mA Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems MSOP-8L and SOP-8L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/ RoHS Compliant (Note 1) General Description The AP393A consists of two independent precision voltage comparators with an offset voltage specification as low as 8.0mV 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, square wave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The AP393A is designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the AP393A will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. Applications • • • • • • 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 Ordering Information A P 3 9 3 A XX G - 13 Package M8 : MSOP-8L S : SOP-8L Package Code M8 S Packaging (Note 2) MSOP-8L SOP-8L Green G : Green Packing 13 : Tape & Reel Device AP393AM8G-13 AP393ASG-13 Notes: 13” Tape and Reel Quantity 2500/Tape & Reel 2500/Tape & Reel Part Number Suffix -13 -13 1.

For operating at high temperatures, the AP393A must be derated based on a 125°C maximum junction temperature and a thermal resistance of 170°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip dissipation very small (PD
