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:
I
CC
= 10 µA/amp: TS27L2 (very low power),
I
CC
= 150 µA/amp: TS27M2 (low power) and
I
CC
= 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).

6. 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.
