Description
Pin connections (top view)
The TS321 is intended for cost-sensitive
applications where space saving is of great
importance. This bipolar op-amp offers the
benefits of a reduced component size (SOT23-5
package), with specifications that match (or are
better than) industry standard devices (like the
popular LM358A, LM324, etc.). The TS321 has
an input common mode range (Vicm) that includes
ground, and therefore can be employed in single
supply applications.

1. Short-circuits from the output to VCC can cause excessive heating if VCC > 15 V. The maximum output current is
approximately 40 mA independent of the magnitude of VCC.
2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base
junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this
diode action, there is also NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the
Op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is driven
negative. This is not destructive and normal output is restored when the input voltage goes back above -0.3V.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers. All values are typical.
4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the
device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations
while the other pins are floating.
6. 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. The CDM value applies to SO-8 only.

2. The direction of the input current is out of the IC. This current is essentially constant and independent of the state of the
output, therefore there is no change in the load on the input lines.

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.
