TS274
High performance CMOS quad ooperational amplifiers
■ Output voltage can swing to ground
■ Excellent phase margin on capacitive loads
■ Gain bandwidth product: 3.5MHz
■ Stable and low offset voltage
■ Three input offset voltage selections
Description
The TS274 devices are low cost, quad operational
amplifiers designed to operate with single or dual
supplies. These operational amplifiers use the ST
silicon gate CMOS process allowing an excellent
consumption-speed ration. These series are ideally
suited for low consumption applications.
Three power consumptions are available allowing
to have always the best consumption-speed ratio:
– ICC = 10µA/amp.: TS27L4 (very low power)
– ICC = 150µA/amp.: TS27M4 (low power)
– ICC = 1mA/amp.: TS274 (standard)
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).
