Description:

The NTE7141 is a dual, operational amplifier in an 8–Lead Mini–DIP type package that combines the advantages of MOS and bipolar transistors on the same monolithic chip. The gate–protected MOSFET (PMOS) input transistors provide high input impredance and a wide common–mode input voltage range (typically to 0.5V below the negative supply rail). The bipolar output transistors allow a wide output voltage swing and provide a high output current capability.

Features:

● Internally Compensated

● MOSFET Input Stage:

Very High Input Impedance

Very Low Input Current

Wide Common–Mode Input Voltage Range

Rugged Input Stage – Bipolar Diode Protected

● Directly Replaces Industry Type 1458 in Most Applications

● Operation From 4V–to–36V Single or Dual Supplies

● Characterized for ±15V Operation for TTL Supply Systems with Operation down to 4V

● Wide Bandwidth

● High Voltage–Follower Slew Rate

● Output Swings to Within 0.5V of Negative Supply at V+ = 5V, V– = 0

Applications:

● Ground–Referenced Single–Supply Amplifiers in Automobile and Portable Instrumentation

● Sample and Hold Amplifiers

● Long–Duration Timers/Multivibrators (Microseconds – Minutes – Hours)

● Photocurrent Instrumentation

● Active Filters

● Intrusion Alarm Systems

● Comparators

● Instrumentation Amplifiers

● Function Generators

● Power Supplies
