TS27L4CDT

TS27L4 Very low power precision CMOS quad operational amplifiers Features ■ Very low power consumption: 10 µA/op ■ Output voltage can swing to ground ■ Excellent phase margin on capacitive loads ■ Unity gain stable ■ Two input offset voltage selections DIP14 (Plastic package) SO-14 (Plastic micropackage) Description 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. These series are ideally suited for low consumption applications. TSSOP14 (Thin shrink small outline package) Three power consumptions are available enabling the best consumption-speed ratio: ICC = 10 µA/amp: TS27L4 (very low power), ICC = 150 µA/amp: TS27M4 (low power), ICC = 1 mA/amp: TS274 (standard). Pin connections (top view) These CMOS amplifiers offer very high input impedance and extremely low input currents. The major advantage versus JFET devices is the very low input current drift with temperature (see Figure 4).

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 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ 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 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). 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. Table 2.
