NTE888M
Integrated Circuit
Low Power Programmable Operational Amplifier
Description:
The NTE888M is an operational amplifier in an 8–Lead DIP type package featuring low power consumption and high input impedance. In addition, the quiescent currents within this device may be
programmed by the choice of an external resistor value or current source applied to the I
This allows the NTE888M’s characteristics to be optimized for input current and power consumption
despite wide variations in operating power supply voltages.
Features:
D ±1.2V to ±18V Operation
D Wide Programming Range
D Offset Null Capability
D No Frequency Compensation Required
D Low Input Bias Currents
D Short–Circuit Protection
