NTE902
Integrated Circuit
Operational Transconductance Amplifier
Description:
The NTE902 has a differential input and a single–ended, push–pull, class A output. In addition there
is a bias input for linear gain control, whose transconductance (g_m) is directly proportional to the ampli-
fier bias current (I_ABC).
Features:
• Slew rate (unity gain, compensated): 50V/µs
• Flexible supply voltage range: ±2V to ±15V
• Fully adjustable gain: 0 to g_m R_L limit
Applications:
• Sample and hold
• Multiplex
• Voltage follower
• Multiplier
• Comparator
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
