LM1458

(ACTIVE) Dual Operational Amplifier

Diagram

Functional Diagram

Description

The LM1458 and the LM1558 are general purpose dual operational amplifiers. The two amplifiers share a common bias network and power supply leads. Otherwise, their operation is completely independent.

The LM1458 is identical to the LM1558 except that the LM1458 has its specifications guaranteed over the temperature range from 0°C to +70°C instead of −55°C to +125°C.

Features

  • No Frequency Compensation Required
  • Short-Circuit Protection
  • Wide Common-Mode and Differential Voltage Ranges
  • Low-Power Consumption
  • 8-Lead TO-99 and 8-Lead PDIP
  • No Latch Up When Input Common Mode Range is Exceeded
