Fast Precise Comparator Has Differential Input Range

AD790 Has Min/Max Specs for Both ±15-Volt and +5-Volt Operation; Propagation Delay is 45 ns Max (±15 V), 50 ns Max (+5 V)

The AD790 is a versatile, fast, precise voltage comparator on a single monolithic chip fabricated in the Analog Devices complementary-bipolar (CB) process, discussed recently in these pages (22-2, 1988, pp. 12-15). It operates on a wide range of supply voltages and is fully specified for performance under two conditions: with a single +5-V supply and with dual ±15-V supplies.  Read full article
