AMS393 GENERAL DESCRIPTION The AMS393 consists of two independent, FEATURES voltage comparators .These were designed Wide supply voltage range specifically to operate Low supply current drain independent of From a single power supply over a wide range of voltages. Operation supply. from split power supplies is also Possible and the Voltage. Low input biasing current, low power supply current drain is independent of Low input offset current the magnitude of the power Supply voltage. The Low input offset voltage outputs can be connected to other open-collector Input common-mode voltage range includes outputs to achieve wired-AND relationships. GND. Differential input voltage range equal to the power supply voltage Low output saturation voltage Output voltage compatible with TTL, MOS and CMOS logic Block Ver1.0 Diagram 1 AMS393 Pin Description Absolute Maximum Ratings Symbol Parameter Value Unit 30 or±15 V ±30 V Vcc Power supply Voltage VIDR lnput Differential Voltage Range(a) VICR lnput Common Mode Voltage Range -0.3 to 30 V TOPR Operating -40 to 80 ℃ Tstg storage Temperature (TA=+25℃) -55 to +125 ℃ 280 ℃ TL Temperature Range Lead Temperatur,1mm from Case for 10 Seconds Maximum Ratings are those Values beyond which damage to the device may occur.
