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

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.
The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output
so no loading change exists on the input lines.
Vo = 1.4V, Rs = 0Ω, 5V < VCC+ < 30V, 0 < Vic < VCC+ - 1.5V.
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V.
The upper end of the common-mode voltage range is VCC+ - 1.5V, but either or both inputs can go to +32V without damage.
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 duration than an input
is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.
