Single LM324, LM358 enhanced version in sot23-5 package
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. 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
Description The TS321 device is intended for cost-sensitive applications where space-saving is of great importance. This bipolar operational amplifier (op amp) offers the benefits of a reduced component size (SOT23-5 package) with specifications that match (or are better than) 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.

Table 2: Operating conditions Electrical characteristics Table 3: Electrical characteristics at VCC+ = 5 V, VCC- = ground, Vo = 1.4 V, Tamb = 25 °C (unless otherwise specified)
Notes: (1) Vo = 1.4 V, Rs = 0 Ω, 5 V < (VCC+ ) < 30 V, 0 < Vicm < (VCC+ ) - 1.5 V
(2) The direction of the input current is out of the IC. This current is essentially constant and independent of the state of the output. Therefore, there is no change in the load on the input lines.

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, VCC and temperature) or even worse, outside of the device’s operating conditions (for example, VCC and Vicm), are not reliable in any way.
