NTE911 integrated circuit dual voltage comparator description: the NTE911 is a dual, dif ferential voltage comparator in a 10 ? lead metal can type package featuring high accuracy, fast response times, large input voltage range, low power consumption and compatibil- ity with practically all integreated logic forms. when used as a sense amplifier, the threshold voltage can be adjusted over a wide range, almost independent of the integrated circuit characteristics. inde- pendent strobing of each comparator channel is provided, and pulse stretching on the output is easily accomplished. other applications of the dual comparator include a window discriminator in pulse height detectors and a double ? ended limit detector for automatic go/no ? go test equipment. features: fast response time ? 40ns typical 5mv maximum offset voltage 10 a maximum offset current independent comparator strobing absolute maximum ratings: positive supply voltage +14v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . negative supply voltage ? 7.0v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . peak output current 50ma . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . differential input voltage 5.0ma . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . input voltage 7.0v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . strobe voltage 0 to +6.0v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . internal power dissipation (t a +70 c) 500mw . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . derate linearly above +70 c 6.3mw/ c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . operating temperature range 0 to +70 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . strobe temperature range ? 65 to +150 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . lead temperature (during soldering, 10sec) +260 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . electrical characteristics : (t a = 25 c, v+ = 12v, v ? = ? 6.0v unless otherwise specified) parameter test conditions min typ max unit input offset voltage v out = +1.4v, r 200 ? ? 1.0 5.0 mv pg out r s 200 ? ? 1.0 7.5 mv r s 200 ? , t a = 0 to +70 q c v cm = 0 ? ? 6.0 mv t a = 0 t o + 70 c note 1 ? ? 10 mv note 1 the input offset voltage is specified for a logic threshold as follows: 1.5v at 0 c, 1.4 at +25 c, 1.2v at +70 c
