The AD790SQ is a fast (45 ns), precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. 

The AD790SQ may operate from either a single +5 V supply or a dual ±15 V supply. 

In the single-supply mode, the AD790’s inputs may be referred to ground, a feature not found in other comparators. 

In the dual-supply mode it has the unique ability of handling a maximum differential voltage of 15 V across its input terminals, easing their interfacing to large amplitude and dynamic signals. 

This device is fabricated using Analog Devices’ Complementary Bipolar (CB) process–which gives the AD790’s combination of fast response time and outstanding input voltage resolution (1 mV max). 

To preserve its speed and accuracy, the AD790 incorporates a “low glitch” output stage that does not exhibit the large current spikes normally found in TTL or CMOS output stages. 

Its controlled switching reduces power supply disturbances that can feed back to the input and cause undesired oscillations. 

The AD790SQ also has a latching function which makes it suitable for applications requiring synchronous operation. 

The AD790SQ is available in five performance grades. 

The AD790J and the AD790K are rated over the commercial temperature range of 0°C to +70°C. 

The AD790A and AD790B are rated over the industrial temperature range of –40°C to +85°C. 

The AD790S is rated over the military temperature range of –55°C to +125°C and is available processed to MIL-STD-883B, Rev. C.
