TS321

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 (SOT23-5package), with
specificationsthat match(orbetter)industrystand­ard devices (like the popular LM358A, LM324,
etc.).TheTS321hasaninputcommonmoderange
(Vicm) that includes ground, thereforecan beem­ployed in singlesupplyapplications.

Notes : 1. Short-circuits from the output to VCCcan cause excessive heating if VCC> 15V. The maximum output current is approximately

2. The direction of the input current is out of the IC. This current is essentially constant,independent of the state of the output

3. Vo = 1.4V, Rs = 0Ω,5V<V

4. The input common-mode voltage of either input signal voltage shouldnot beallowed togo negative by more than 0.3V.

5. This input current only exists when the voltage at any of theinput leads is driven negative. It is due to the collector-base

Equivalent Input Noise Voltage

40mA independent ofthe magnitude of V
so no loading change exists on the input lines.

The upper end of the common-mode voltage range is V
junction of the input PNP transistor becoming forward biased andthereby acting as input diodes clamps.

In addition to thisdiode action, there is also NPN parasitic action on theIC chip. this transistor action can cause the output
voltages of the Op-amps to go to the V
is driven negative. Thisisnot destructive and normal output will set up again for input voltage higher than -0.3V.
