NTE902 NTE

NTE902 Integrated Circuit Operational Transconductance Amplifier Description: The NTE902 has a differential input and a singleended, pushpull, class A output. In addition there is a bias input for linear gain control, whose transconductance (g ) is directly proportional to the ampli- m fier bias current (I ). ABC Features: Slew rate (unity gain, compensated): 50V/ s Flexible supply voltage range: 2V to 15V Fully adjustable gain: 0 to g R limit m L Applications: Sample and hold Multiplex Voltage follower Multiplier Comparator Absolute Maximum Ratings: (T = +25C unless otherwise specified) A DC Supply Voltage (between V+ and V Pins) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V Differential Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5V DC Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
