The AD790 is a fast (45 ns), precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. The AD790 may operate from either a single +5 V supply or a dual ±15 V supply. In the single-supply mode, the AD790's inputs maybe 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.

The 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 (1mV 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 AD790 also has a latching function which makes it suitable for applications requiring synchronous operation.

The AD790 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 to MIL-STD-883B, Rev. C.

PRODUCT HIGHLIGHTS

  1. The AD790’s combination of speed, precision, versatility and low cost makes it suitable as a general purpose comparator in analog signal processing and data acquisition systems.
  2. Built-in hysteresis and a low-glitch output stage minimize the chance of unwanted oscillations, making the AD790 easier to use than standard open-loop comparators.
  3. The hysteresis combined with a wide input voltage range enables the AD790 to respond to both slow, low level (e.g., 10 mV) signals and fast, large amplitude (e.g., 10 V) signals.
  4. A wide variety of supply voltages is acceptable for operation of the AD790, ranging from single 5 V to dual +5 V/–12 V, ±5 V, or +5 V/±15 V supplies.
  5. The AD790’s power dissipation is the lowest of any comparator in its speed range.
  6. The AD790’s output swing is symmetric between VLOGIC and ground, thus providing a predictable output under a wide range of input and output conditions.
