TS27L4 Very low power precision CMOS quad operational amplifiers Features ■ Very low power consumption: 10µA/op ■ Output voltage can swing to ground DIP14 ■ Excellent phase margin on capacitive loads (Plastic package) ■ Unity gain stable ■ Two input offset voltage selections Description SO-14 (Plastic micropackage) The TS27L4 series are low-cost, low-power quad operational amplifiers designed to operate with single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process allowing an excellent consumption-speed ratio. TSSOP14 These series are ideally suited for low (Thin shrink small outline package) consumption applications. Three power consumptions are available enabling Pin connections (top view) the best consumption-speed ratio: I = 10µA/amp: TS27L4 (very low power), CC I = 150µA/amp: TS27M4 (low power), CC Output 1 1 14 Output 4 I = 1mA/amp: TS274 (standard). CC Inverting Input 1 2 - - 13 Inverting Input 4 These CMOS amplifiers offer very high input Non-inverting Input 1 3 + + 12 Non-inverting Input 4 impedance and extremely low input currents. The VC C + 4 11 VCC- major advantage versus JFET devices is the very Non-inverting Input 2 5 + + 10 Non-inverting Input 3 low input current drift with temperature (see Inverting Input 2 6 - - 9 Inverting Input 3 Figure4).

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. 4. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 5. Human body model: a 100pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: a 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of connected pin combinations while the other pins are floating. 7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. T able 2.
