GENERAL DESCRIPTION  
OP470  
10 OUT C  
NC  
The OP470 is a high-performance monolithic quad operational  
amplifier with exceptionally low voltage noise, 5 nV/÷Hz at  
1 kHz max, offering comparable performance to ADI’s industry  
standard OP27.

The OP470 features an input offset voltage below 0.4 mV,  
excellent for a quad op amp, and an offset drift under 2 mV/∞C,  
guaranteed over the full military temperature range. Open loop  
gain of the OP470 is over 1,000,000 into a 10 kW load ensuring  
excellent gain accuracy and linearity, even in high gain applica-  
tions. Input bias current is under 25 nA, which reduces errors  
due to signal source resistance. The OP470’s CMR of over 110  
dB and PSRR of less than 1.8 mV/V significantly reduce errors  
due to ground noise and power supply fluctuations. Power  
consumption of the quad OP470 is half that of four OP27s, a  
significant advantage for power conscious applications. The  
OP470 is unity-gain stable with a gain bandwidth product of  
6 MHz and a slew rate of 2 V/ms.  
The OP470 offers excellent amplifier matching which is impor-  
tant for applications such as multiple gain blocks, low noise  
instrumentation amplifiers, quad buffers, and low noise active  
filters.  
The OP470 conforms to the industry standard 14-lead DIP  
pinout. It is pin compatible with the LM148/149, HA4741,  
HA5104, and RM4156 quad op amps and can be used to up-  
grade systems using these devices.  
For higher speed applications, the OP471, with a slew rate of 8  
V/ms, is recommended.
