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:
■
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

1. All values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive
supply voltage.
4. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
7. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

Macromodel
4.1
Important note concerning this macromodel
Please consider the following remarks before using this macromodel.
●
All models are a trade-off between accuracy and complexity (i.e. simulation time).
●
Macromodels are not a substitute to breadboarding; rather, they confirm the validity of
a design approach and help to select surrounding component values.
●
A macromodel emulates the nominal performance of a typical device within specified
operating conditions (temperature, supply voltage, for example). Thus the
macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the
main parameters of the product.
Data derived from macromodels used outside of the specified conditions (VCC, temperature,
for example) or even worse, outside of the device operating conditions (VCC, Vicm, for
example), is not reliable in any way.
