Description

The TS27x2 series are low-cost and low-power dual operational amplifiers designed to operate with high-voltage single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process, providing an excellent consumption-speed ratio thanks to three different power consumptions, making them ideal for low consumption applications:

ICC = 10 ?A/amp: TS27L2 (very low power),

ICC = 150 ?A/amp: TS27M2 (low power) and

ICC = 1 mA/amp: TS272 (high speed)

The devices also offer a very high input impedance and extremely low input currents. Their main advantage compared to JFET devices is the very low input current drift with temperature (Figure 3).
