TS321 Low-power single operational amplifier Datasheet - production data Description The TS321 device is intended for cost-sensitive applications where space-saving is of great importance. This bipolar operational amplifier SOT23-5 (op amp) offers the benefits of a reduced (plasticpackage) component size (SOT23-5 package) with specifications that match (or are better than) Pinconnections(topview) industry standard devices (such as the popular LM358A, LM324, and other similar devices). The TS321 device has an input common mode range (Vicm) that includes ground and therefore can be employed in single supply applications. Features • Large output voltage swing − 0 to 3.5 V min (V = 5 V) CC • Low supply current: 500 µA • Low input bias current: 20 nA • Low input offset voltage − 2 mV max. for TS321A − 4 mV max. for TS321 • Wide power supply range − Single supply: 3 to 30 V − Dual supplies: ±1.5 to ±15 V • Stable with high capacitive loads November 2014 DocID6298 Rev 9 1/15 This is information on a product in full production. www.st.com

Absolute maximum ratings and operating TS321 conditions 2 Absolute maximum ratings and operating conditions Table 1: Absolute maximum ratings Symbol Parameter Value Unit VCC+ Supply voltage ±16 to 32 Vin Input voltage -0.3 to 32 V Vid Differential input voltage ±32 Output short-circuit duration (1) Infinite Iin Input current (2) 50 mA Tstg Storage temperature range -65 to 150 °C Tj Maximum junction temperature 150 Rthja Thermal resistance junction-to-ambient (3) 250 °C/W Rthjc Thermal resistance junction-to-case (3) 81 HBM: human body model (4) 500 ESD MM: machine model (5) 200 V CDM: charged device model (6) 1000 Notes: (1) 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 amp 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 -0.3 V. (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 ground through only one pin. This is done for all pins.

Macromodel TS321 4 Macromodel 4.1 Important note concerning this macromodel Please not the following points before using this macromodel • All models are a trade-off between accuracy and complexity (that is, simulation time) • Macromodels are not a substitute for 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 (for example, temperature and supply voltage). 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 the specified conditions (for example, V CC and temperature) or even worse, outside of the device’s operating conditions (for example, V and Vicm), are not reliable in any way.
