The TS274 series are low cost, low power quad operational amplifiers designed to operate with single or dual supplies. These operational amplifi- ers use the SGS-THOMSON silicon gate CMOS process allowing an excellent consumption-speed ratio. These series are ideally suited for low con- sumption applications.
Three power consumptions are available allowing to have always the best consumption-speed ratio : · ICC=10µA/amp. : TS27L4 (very lowpower) · ICC= 150µA/amp. : TS27M4 (low power) · ICC= 1mA/amp. : TS274 (high speed)
These CMOS amplifiers offer very high input im-pedance and extremely low input currents.
The major advantage versus JFET devices is the very low input currents drift with temperature (see figure 2).
