Description
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 (V icm) that includes ground, and therefore can be employed in single supply applications.

1 Circuit schematics
Figure 1. Schematic diagram
2 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings
- Short-circuits from the output to V CC can cause excessive heating if VCC > 15V. The maximum output current is
approximately 40mA independent of the magnitude of VCC.
- This input current only exists when the voltage at any of t he input leads is driven negative. It is due to the collector-base
negative. This is not destructive and normal output is restored when the input voltage goes back above -0.3V.
- Short-circuits can cause ex cessive heating. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers. All values are typical.
- 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.
- Machine model: A 200pF capacitor is char ged to the specified voltage, then discharged directly between two pins of the
while the other pins are floating.
- Charged device model: all pins and the pac kage 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. Table 2. Operating conditions

- 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.
4 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.
