TS321 Low power single operational amplifier Features ■ ■ ■ ■ ■ Large output voltage swing: 0 to 3.5 V min. (VCC = 5 V) Low supply current: 500 µA Low input bias current: 20 nA Low input offset voltage: 2 mV max. Wide power supply range: – Single supply: +3 V to +30 V – Dual supplies: ±1.5 V to ±15 V Stable with high capacitive loads SO-8 (Plastic micropackage) ■ SOT23-5 (Plastic package) 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 (Vicm) that includes ground, and therefore can be employed in single supply applications. Pin connections (top view) N.C.

Short-circuits from the output to VCC can cause excessive heating if VCC > 15 V. The maximum output current is approximately 40 mA 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 during which an input is driven negative. This is not destructive and normal output is restored when the input voltage goes back above -0.3V. 3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. All values are typical. 4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. 6. Charged device model: all pins and the package 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. 3/13 Absolute maximum ratings and operating conditions Table 2.

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. 4.2 Macromodel code ** 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 8/13 TS321 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 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 Macromodel 4.3 Macromodel electrical characteristics Table 4.
