TS27L4
Very low power precision CMOS quad operational amplifiers
Features
■ Very low power consumption: 10 µA/op
■ Output voltage can swing to ground
■ Excellent phase margin on capacitive loads
■ Unity gain stable
■ Two input offset voltage selections
Description
The TS27L4 series 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 enabling
the best consumption-speed ratio:
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 current drift with temperature (see
Figure 4).
