GENERAL DESCRIPTION  
The OP400 is the first monolithic quad operational amplifier  
that features OP77-type performance. Precision performance is  
not sacrificed with the OP400 to obtain the space and cost  
savings offered by quad amplifiers.  
The OP400 features low power consumption, drawing less than  
725 µA per amplifier. The total current drawn by this quad  
amplifier is less than that of a single OP07, yet the OP400 offers  
significant improvements over this industry-standard op amp.  
Voltage noise density of the OP400 is a low 11 nV/√Hz at  
10 Hz, half that of most competitive devices.  
The OP400 features an extremely low input offset voltage of less  
than 150 µV with a drift of less than 1.2 µV/°C, guaranteed over  
the full military temperature range. Open-loop gain of the  
OP400 is more than 5 million into a 10 kΩ load, input bias  
current is less than 3 nA, CMR is more than 120 dB, and PSRR  
is less than 1.8 µV/V. On-chip Zener zap trimming is used to  
achieve the low input offset voltage of the OP400 and eliminates  
the need for offset nulling. The OP400 conforms to the industry-  
standard quad pinout, which does not have null terminals.  
The OP400 is an ideal choice for applications requiring multiple  
precision operational amplifiers and where low power  
consumption is critical.
