TS271 CMOS Programmable Low Power Single Operational Amplifier Offset null capability (by external compensation) Dynamic characteristics adjustable I SET Consumption current and dynamic parameters are stable regarding the N voltage power supply variations DIP8 Output voltage can swing to ground (Plastic Package) Very large I range SET Stable and low offset voltage Three input offset voltage selections Description D SO-8 The TS271 is a low cost, low power single (Plastic Micropackage) operational amplifier designed to operate with single or dual supplies. This operational amplifier uses the ST silicon gate CMOS process giving it Pin Connections (top view) an excellent consumption-speed ratio. This amplifier is ideally suited for low consumption applications. 1 8 The power supply is externally programmable with a resistor connected between pins 8 and 4. It 2 7 - allows to choose the best consumption-speed + 3 6 ratio and supply current can be minimized 45 according to the required speed. This device is specified for the following I current values: SET 1.5A, 25A, 130A. 1 - Offset Null 1 2 - Inverting Input 1 3 - Non-inverting Input 1 This CMOS amplifier offers very high input - 4 - V CC impedance and extremely low input currents. The 5 - Offset Null 2 6 - Output major advantage versus JFET devices is the very + 7 - V CC low input currents drift with temperature see 8 - I Set Figure 8, Figure 19, Figure 30.
