may 2010 doc id 6298 rev 7 1/15 15 ts321 low-power single operational amplifier features large output voltage swing: 0 to 3.5 v min. (v cc = 5 v) low supply current: 500 a 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 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 (such as the popular lm358a, lm324, and as such). the ts321 has an input common-mode range (v icm ) that includes ground and therefore can be employed in single-supply applications. so-8 (plastic micropackage) sot23-5 (plastic package) pin connections (top view)

macromodel ts321 8/15 doc id 6298 rev 7 4 macromodel 4.1 important note concerning this macromodel note the following remarks before using the macromodel. all models are a trade-off between accuracy and complexity (that is, simulation time). 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 ex haustive as the datasheet, it s purpose is to illustrate the main parameters of the product. data derived from macromodels used ou tside of the specified conditions (v cc , temperature, for example) or even worse, outside of the device?s operating conditions (v cc , v icm , 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
