APPLICATION INFORMATION  
Figure 1 shows the basic connections required for operation  
of the INA101. (Pin numbers shown are for the TO-100  
metal package.) Applications with noisy or high impedance  
power supplies may require decoupling capacitors close to  
the device pins as shown.  
The 40kterm in equation (1) comes from the sum of the  
two internal feedback resistors. These are on-chip metal film  
resistors which are laser trimmed to accurate absolute val-  
ues. The accuracy and temperature coefficient of these  
resistors are included in the gain accuracy and drift specifi-  
cations of the INA101.  
The output is referred to the output Common terminal which  
is normally grounded. This must be a low-impedance con-  
nection to assure good common-mode rejection. A resis-  
tance greater than 0.1in series with the Common pin will  
cause common-mode rejection to fall below 106dB.  
The stability and temperature drift of the external gain  
setting resistor, RG, also affects gain. RG’s contribution to  
gain accuracy and drift can be directly inferred from the gain  
equation (1). Low resistor values required for high gain can  
make wiring resistance important. Sockets add to the wiring  
resistance which will contribute additional gain error (possi-  
bly an unstable gain error) in gains of approximately 100 or  
greater. The gain sense connections on the DIP and SOL-16  
packages (see Figure 2) reduce the gain error produced by  
wiring or socket resistance.  
SETTING THE GAIN  
Gain of the INA101 is set by connecting a single external  
resistor, RG:
