r-. analog w devices general purpose low cost ic operational amplifier features low bias and offset current single capacitor external compensation for operating flexibility nullable offset voltage no latch-up fully short circuit protected wide operating voltage range general description the analog devices adioia, ad201a, ad301a and ad301al are high performance monolithic operational ampli- fiers. all the circuits feature full short circuit protection, ex- ternal offset voltage nulling, wide operating voltage range, and the total absence or "latch-up". because frequency compensa- tion is performed externally with a single capacitor (30pf maximum), the ad lola, ad20la, ad30la and ad30lal provide greater flexibility than internally compensated ampli- fiers since the degree of compensation can be fitted to the specific system application. the adlola and ad20la have identical specifications in the to-99 package; the former guaranteed over the -55c to +12soc temperature range, and the latter over ~2soc to +8soc. the ad20la is also available in the mini-dip package for high performance operation over the 0 to +70c temperature range. the ad30la is specified for operation over the 0 to +70c temperature range in both the to-99 and mini-dip packages. the ad30lal is the highest accuracy version of this series. improved processing and additional electrical testing allow the user to achieve precision performance at low cost. the device provides substantially increased accuracy by reducing errors due to offset voltage (o.smv max), offset voltage drift (s.opv /c max), bias current (30na max), offset current (sna max), voltage gain (80,000 min), psrr (90db min), and cmrr (90db min). the ad30lal is also specified from 0 to +70 c and is available in the to-99 can or 8-pin mini-dip. schema tic diagram compensation compensation 1) r; rb 1k v- connection diagrams (top view) to-99 mini-dip comp:.:s~~~g~ l! inverting input [2 b icompensation non.'nve~j:~~ 13 operational amplifiers 17 --- obsolete
