AD790AQ Description

Short technical summary and product information.

The AD790AQ is a fast, precision voltage comparator manufactured by Analog Devices. It features a propagation delay of 45 ns maximum and an input offset voltage of 250 µV maximum, ensuring high-speed and accurate comparisons. The device includes an onboard latch for holding the output state, and its output is compatible with both CMOS and TTL logic levels.

 

The comparator can operate from a single 5 V supply or dual ±15 V supplies, making it versatile for various system designs. It has a maximum differential input voltage of 15 V and a typical power dissipation of 60 mW. The input hysteresis is 500 µV maximum, which helps prevent oscillations near the threshold.

 

The AD790AQ is housed in an 8-pin CDIP (Ceramic DIP) package with through-hole mounting, and the supplier device package is 8-CERDIP. It is suitable for applications such as zero-crossing detectors, overvoltage detectors, pulse-width modulators, precision rectifiers, and discrete A/D converters. The operating temperature range is -40°C to 85°C, covering industrial environments.
