SO-8  
The TS271 is a low cost, low power single  
operational amplifier designed to operate with  
single or dual supplies. This operational amplifier  
uses the ST silicon gate CMOS process giving it  
an excellent consumption-speed ratio. This  
amplifier is ideally suited for low consumption  
applications.

The power supply is externally programmable with  
a resistor connected between pins 8 and 4. It  
allows to choose the best consumption-speed  
ratio and supply current can be minimized  
according to the required speed. This device is  
-
+
specified for the following I  
1.5µA, 25µA, 130µA.  
current values:  
SET  
1 - Offset Null 1  
2 - Inverting Input 1  
3 - Non-inverting Input 1  
This CMOS amplifier offers very high input  
impedance and extremely low input currents. The  
major advantage versus JFET devices is the very  
low input currents drift with temperature see  
Figure 8, Figure 19, Figure 30.

1) All values, except differential voltage are with respect to network ground terminal.  
2) Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.  
3) The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage.
