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) industry standard devices (like the popular
LM358A, LM324, etc.). The TS321 has an input
common mode range (V
and therefore can be employed in single supply
applications.

1. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is
approximately 40mA 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 V
negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all
amplifiers. All values are typical.
4. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
5. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external
series resistor (internal resistor < 5Ω), into pin to pin of device.
