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 lowconsumption applications: ICC = 10 µA/amp: TS27L2 (very low power), ICC = 150 µA/amp: TS27M2 (low power) and ICC = 1 m A/amp: TS272 (high speed)
The devices also offer a very high input impedance and extremely low input currents. Their main advantage pared to JFET devices is the very low input current drift with temperature (Figure 3).
