GENERAL DESCRIPTION  
This low noise bipolar input op amp is also a cost effective  
alternative to chopper-stabilized amplifiers. The OP177 provides  
chopper-type performance without the usual problems of high  
noise, low frequency chopper spikes, large physical size, limited  
common-mode input voltage range, and bulky external storage  
capacitors.  
The OP177 features the highest precision performance of any  
op amp currently available. Offset voltage of the OP177 is only  
10 µV max at room temperature and 20 µV max over the full  
military temperature range of –55°C to +125°C. The ultralow  
V
OS of the OP177, combines with its exceptional offset voltage  
drift (TCVOS) of 0.1 µV/°C max, to eliminate the need for  
external VOS adjustment and increases system accuracy over  
temperature.  
The OP177 is offered in both the –55°C to +125°C military,  
and the –40°C to +85°C extended industrial temperature  
ranges. This product is available in 8-pin ceramic and epoxy  
DIPs, as well as the space saving 8-pin Small-Outline (SO) and  
the Leadless Chip Carrier (LCC) packages.  
The OP177’s open-loop gain of 12 V/µV is maintained over the  
full ±10 V output range. CMRR of 130 dB min, PSRR of  
120 dB min, and maximum supply current of 2 mA are just a  
few examples of the excellent performance of this operational  
amplifier. The OP177’s combination of outstanding specifications  
insure accurate performance in high closed-loop gain applications.
