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 (Vicm) that includes ground, and 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 . 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 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. 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. 3/12 Electrical Characteristics TS321 3 Table 2.

This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3. 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. 5/12 Electrical Characteristics Figure 2. ICC = f(t) Figure 3.

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 (i.e. temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main parameters of the product. Data issued from macromodels used outside of its specified conditions (Vcc, Temperature, etc) or even worse: outside of the device operating conditions (Vcc, Vicm, etc) are not reliable in any way. ** Standard Linear Ics Macromodels, 1993. ** CONNECTIONS : * 1 INVERTING INPUT * 2 NON-INVERTING INPUT * 3 OUTPUT * 4 POSITIVE POWER SUPPLY * 5 NEGATIVE POWER SUPPLY .SUBCKT TS321 1 2 3 4 5 *************************** .MODEL MDTH D IS=1E-8 KF=3.104131E-15 CJO=10F * INPUT STAGE CIP 2 5 1.000000E-12 CIN 1 5 1.000000E-12 EIP 10 5 2 5 1 EIN 16 5 1 5 1 RIP 10 11 2.600000E+01 RIN 15 16 2.600000E+01 RIS 11 15 2.003862E+02 DIP 11 12 MDTH 400E-12 DIN 15 14 MDTH 400E-12 VOFP 12 13 DC 0 VOFN 13 14 DC 0 IPOL 13 5 1.000000E-05 CPS 11 15 3.783376E-09 DINN 17 13 MDTH 400E-12 VIN 17 5 0.000000e+00 DINR 15 18 MDTH 400E-12 VIP 4 18 2.000000E+00 FCP 4 5 VOFP 3.400000E+01 FCN 5 4 VOFN 3.400000E+01 FIBP 2 5 VOFN 2.000000E-03 FIBN 5 1 VOFP 2.000000E-03 * AMPLIFYING STAGE FIP 5 19 VOFP 3.600000E+02 FIN 5 19 VOFN 3.600000E+02 RG1 19 5 3.652997E+06 RG2 19 4 3.652997E+06 CC 19 5 6.000000E-09 7/12 Macromodel DOPM 19 22 MDTH 400E-12 DONM 21 19 MDTH 400E-12 HOPM 22 28 VOUT 7.500000E+03 VIPM 28 4 1.500000E+02 HONM 21 27 VOUT 7.500000E+03 VINM 5 27 1.500000E+02 EOUT 26 23 19 5 1 VOUT 23 5 0 ROUT 26 3 20 COUT 3 5 1.000000E-12 DOP 19 25 MDTH 400E-12 VOP 4 25 2.242230E+00 DON 24 19 MDTH 400E-12 VON 24 5 7.922301E-01 .ENDS Table 3.
