ciao tutti, ho realizzato qualche tempo fa un dac (digital-analog-converter) ad 8 bit basato sulla rete r-2r http://en.wikipedia.org/wiki/resistor_ladder , con l'arrivo dell'oscilloscopio ho provato verificare quali prestazioni poteva offrirmi. all'uscita ho inserito un amplificatore operazionale lm358 in configurazione inseguitore di tensione http://it.wikipedia.org/wiki/inseguitore_di_tensione e questo ha limitato diciamo l'escursione massima 3.88 volt al posto dei 5 canonici, risolvibile alimentando con una tensione superiore l'integrato o utilizzando un op-amp equivalente rail-to-rail. ho notato generando una sinusoide (codice sperimentale in allegato) però che il segnale che ottengo è abbastanza "sporco", presenta dei picchi anche elevati che si attenuano al calare della frequenza, ecco la schermata dell'oscilloscopio (sinusoide 73 hz): cos'è secondo voi? una sorta di limite dovuto alle resistenze che ho scelto (9k e 18k) o al...
