FEATURES  
DESCRIPTION  
The LF442 dual low power operational amplifiers  
provide many of the same AC characteristics as the  
industry standard LM1458 while greatly improving the  
DC characteristics of the LM1458. The amplifiers  
have the same bandwidth, slew rate, and gain (10 kΩ  
load) as the LM1458 and only draw one tenth the  
supply current of the LM1458. In addition the well  
matched high voltage JFET input devices of the  
LF442 reduce the input bias and offset currents by a  
factor of 10,000 over the LM1458. A combination of  
careful layout design and internal trimming ensures  
very low input offset voltage and voltage drift. The  
LF442 also has a very low equivalent input noise  
voltage for a low power amplifier.

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: 10 μV/°C (max)  
High Gain Bandwidth: 1 MHz  
High Slew Rate: 1 V/μs  
Low Noise Voltage for Low Power: 35 nV/Hz  
Low Input Noise Current: 0.01 pA/Hz  
High Input Impedance: 1012Ω  
High Gain VO = ±10V, RL = 10k: 50k (min)  
The LF442 is pin compatible with the LM1458  
allowing an immediate 10 times reduction in power  
drain in many applications. The LF442 should be  
used where low power dissipation and good electrical  
characteristics are the major considerations.
