Adjustable DC Offset with an LM1458
Hello everyone! I hope you all feel good and having fun. Today, I am going to introduce you about LM1458. LM1458 is a dual general purpose operational amplifier (Op-amp). This article mainly introduce its pinout, applications, datasheet and other detailed information about Texas Instruments LM1458.
LM1458M
LM1458 is a dual general purpose Operational Amplifier (Op-amp). Its has two builtin amplifiers having common power supply as well as common mode voltage. This condition is to make both of the amplifiers dependent on each other.
LM1458 has its specifications guaranteed over the temperature range from 0˚C to +70˚C. It has several amazing features. For example, low power consumption, lath-up free operation, short circuit protection,require no external components for frequency compensation, etc.
High common mode voltage range and absence of “latch up" make the LM1458 ideal for use as voltage followers. The high gain and wide range of operating voltage provides superior performance in integrator, summing amplifier and general feedback applications.
