TS27M4AMP

Precision low power CMOS quad operational amplifiers

STMicroelectronics 

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).
