  • Description courte
  • Precision low power CMOS quad operational amplifiers

    Low power consumption: 150 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)


    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 thus offering the best consumption-speed ratio for your application:

    ICC = 10 µA/amp: TS27L4 (very low power) ICC = 150 µA/amp: TS27M4 (low power) ICC = 1 mA/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 4 on page 7).
