DESCRIPTION The TS271 is a low cost, low power single opertional 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 ISET current values : 1.5µA, 25µA, 130µA. 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 3). ORDER CODE
