Virtual eval. of some LoVo OpAmp.-s

 is what the title says :

Text as a text :

Pass TEST *TLV314 -- struggles near rails but passes (1.8÷5.5V)* TLV2371 -- inp max 2.58V *TLV9102 -- struggles near the low rail but passes (2.7÷16V)* TL3472 -- inp min max 1.0 to 3.4 V OPA2990 -- inp max 2.49V *OP284 struggles near rails but passes better the TLV314 (3÷36V)* !!! -- MC33071 -- is over idealized model -- !!! (no significant problems) LMV824 -- inp MAX ? 3.1 to 3.8 V (exact value indeterminable) *LM7321 -- struggles near the rails but passes smoother than OP284 (2.5÷32V)* *LM6142 -- same as LM7321 but faster (1.8÷24V)* LM358 -- min max 404 to 2097 mV !!! a MACRO MODEL   ( the transistor model requires a scaled input to prevent the spurious oscillation !!! ) *AD8628 -- struggles near rails but passes somewhat worse the rest R2R passers (2.7÷5V)*

note : if there will be no spurious oscillations configuring the LM358 , LM324 as the unity buffer shown at above fig. then the sentence "the transistor model requires a scaled input to prevent the spurious oscillation" has no meaning in real-life otherwise the recommended biasing scheme is as http://tinyurl.com/yyvgyz32
