TS274

High performance CMOS quad operational amplifier

Features

■ Output voltage can swing to ground

■ Excellent phase margin on capacitive loads

■ Gain bandwidth product: 3.5 MHz

■ Unity gain stable

DIP14

(Plastic package)

■ Two input offset voltage selections

Description

SO-14

(Plastic micropackage)

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

giving an excellent consumption-speed ratio.

These series are ideally suited for low

consumption applications.

TSSOP14

(Thin shrink small outline package)

Three power consumptions are available thus

offering the best consumption-speed ratio for your

application:

= 150 µA/amp: TS27M4 (low power)

= 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 5 on page 6).

For enhanced features of TS274, in particular rail-

to-rail capability and low offset voltage, two new

families, TSV91x and TSV99x will better suit low

voltage applications.
