GM393
LOW POWER DUAL DIFFERENTIAL COMPARATOR
Description
The GM393 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 commonmode 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 Simple Analog to Digital Converters Pulse, Square Wave Generators Wide Range VCO MOS Clock Timer

Response Time (Note 1)
s 0.3
All characteristics are measured under open loop conditions with zero common-mode input voltage unless otherwise specified. "MAX" VCC for testing purposes is 30V. Full range is 0C to 70C. ** The voltage at either input or common - mode should not be allowed to go negative by more than 0.3V. The upper end of the common - mode voltage range is VCC - 1.5V, but either or both inputs can go to 30V without damage. Note 1: CL includes probe and jig capacitance. The response time specified is the interval between the input step function and the instant when the output crosses 1.4V.
