NTE7141 Integrated Circuit Dual BIMOS Operational Amplifier w/MOSFET Input, Bipolar Output
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: D Internally Compensated D MOSFET Input Stage: Very High Input Impedance Very Low Input Current Wide Common-Mode Input Voltage Range Rugged Input Stage - Bipolar Diode Protected D Directly Replaces Industry Type 1458 in Most Applications D Operation From 4V-to-36V Single or Dual Supplies D Characterized for 15V Operation for TTL Supply Systems with Operation down to 4V D Wide Bandwidth D High Voltage-Follower Slew Rate D Output Swings to Within 0.5V of Negative Supply at V+ = 5V, V- = 0 Applications: D Ground-Referenced Single-Supply Amplifiers in Automobile and Portable Instrumentation D Sample and Hold Amplifiers D Long-Duration Timers/Multivibrators (Microseconds - Minutes - Hours) D Photocurrent Instrumentation D Active Filters D Intrusion Alarm Systems D Comparators D Instrumentation Amplifiers D Function Generators D Power Supplies
