TS27M4C, TS27M4I, TS27M4M
Precision low power CMOS quad operational amplifiers
Features
■ Low power consumption: 150 µA/op
■ Output voltage can swing to ground
■ Excellent phase margin on capacitive loads
■ Unity gain stable
■ Two input offset voltage selections
Description
These devices are low cost, low power 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 ratio.
These series are ideally suited for low
consumption applications.
Three power consumptions are available thus
offering the best consumption-speed ratio for your
application:
■ ICC = 10 µA/amp: TS27L4 (very low power)
■ ICC = 150 µA/amp: TS27M4 (low power)
■ ICC = 1 mA/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 4 on page 7).
