TS27L4

Very low power precision CMOS quad operational amplifiers

Features

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:

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).
