Features
• Internal frequency compensation
• Short circuit protecion
• Large common mode and differential voltage range
• No latch up
• Low power consumption
Description
The LM1458/LM1458C series are dual general purpose
operational amplifiers, having short circuits protected and
require no external components for frequency
compensation. High common mode voltage range and
absence of “latch up" make the LM1458 ideal for use as
voltage follower s. The high ga in an d wide range of op erati ng
voltage provides superior performance in integrator,
summing amplifier and general feedback applications.
