NTE996

NTE996 Linear Integrated Circuit Operational Transconductance Amplifier Description: The NTE996 is a programmable transconductance block intended to fulfill a wide variety of variable gain applications. This device has differential inputs and high impedance push–pull outputs. The NTE996 has high input impedance and its transconductance (gm) is directly proportional to the amplifier bias current (IABC). High slew rate together with programmable gain make the NTE996 an ideal choice for variable gain applications such as sample and hold, multiplexing, filtering, and multiplying, Features: D Slew Rate (Unity Gain Compensated): 50V/µs D Fully Adjustable Gain: 0 to gm • RL Limit D Extended gm Linearity: 3 Decades D Flexible Supply Voltage Range: ±2V to ±18V D Adjustable Power Consumption Absolute Maximum Ratings: DC Supply Voltage, VS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±18V Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 250mW Differential Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±5V Amplifier Bias Current, IABC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2mA DC Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +VS to –VS Output Short Circuit Duration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
