LF442CN Product Details
LF442CN Description
The LF442CN is a dual low power operational amplifier providing many of the same AC characteristics as the industry standard LM1458 while greatly improving the DC characteristics of the LM1458. The LF442CN amplifier has the same bandwidth, slew rate, and gain (10 k load) as the LM1458 and only draw one tenth the supply current of the LM1458. The LF442CN opamp also has a very low equivalent input noise voltage for a low power amplifier. The LF442CN amplifier should be used where low power dissipation and good electrical characteristics are the major considerations.
LF442CN Features
? 1/10 Supply Current of a LM1458: 400 μA (Max) ? Low Input Bias Current: 50 pA (Max) ? Low Input Offset Voltage: 1 mV (Max) ? Low Input Offset Voltage Drift: 7 μV/°C (Typ) ?
