  • These devices 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.

    Three power consumptions are available allowing to have always the best consumption-speed ratio: I CC= 10µA/amp.: TS27L4 (very low power) I CC= 150µA/amp.: TS27M4 (low power) I CC= 1mA/amp.: TS274 (standard)
    These CMOS amplifiers offer 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 2).

    Key Features

    • Low power consumption: 150 µA/op
    • Excellent phase margin on capacitive loads
    • Output voltage can swing to ground
    • Two input offset voltage selections
    • Unity gain stable
