DESCRIPTION
Three power consumptions are available allowing to have always the best consumption-speed ratio : q ICC= 10µA/amp. : TS27L2 (very low power) q ICC= 150µA/amp. : TS27M2 (low power) q ICC= 1mA/amp. : TS272 (high speed) 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).
