MICROELECTRONICS A A Signal Conditioning GM393 LOW POWER DUAL DIFFERENTIAL COMPARATOR Description The GM393 consist 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, square wave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The GM393 are designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the GM393 will directly interface with MOS logic, where their low power drain is a distinct advantage over standard comparators. The GM393 is available in DIP-8 and SOP-8 packages. Features Single- supply Range: ±1.0V to ±18V Wide supply voltage range: ±2.0V to ±36V 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 Application High precision comparators Reduced VOS drift over temperature Eliminates need for dual supplies Allows sensing near GND Compatible with all forms of logic Power drain suitable for battery operation CONNECTION DIAGRAM (Top View) Output A 1 8 VCC Inverting Input A- 2 A + + B 7 Output B NON - Inverting Input A+ 3 6 Inverting Input B- GND 4 SOP-8, DIP-8 PACKAGE 5 NON - Inverting Input B+ www.gammamicro.com GM393 V0.1 1 - MICROELECTRONICS A A Signal Conditioning GM393 LOW POWER DUAL DIFFERENTIAL COMPARATOR MARKING INFORMATION & PIN CONFIGURATIONS SOP-8 Output B VCC Input BInput B+ Output B VCC DIP - 8 Input BInput B+ 8 7 6 5 8 7 6 5 GM393 AYWW 1 Output A Inputs A- GM393 AYWW 1 VEE/ GND Inputs A+ Output A Inputs A- 2 3 4 2 3 4 VEE/ GND Inputs A+ A : Assembly Location Y : Year W W : Weekly ORDERING INFORMATION Ordering Number GM393D8T GM393S8T GM393S8R Package DIP-8 SOP-8 S OP-8 Shipping 60 Units / Tube 100 Units / Tube 2,500 Units /Tape & Reel * For detail Ordering Number identification, please see last page.
