,. W LowCost, HighSpeed,IC Operational Amplifier ANALOG DEVICES FEATURES High Slew Rate: 70V /J1.s Wide Bandwidth: 12MHz 60° Phase Margin (At Unity Gain Crossover) Drives 300pF Load Guaranteed Low Offset Drift: 15J1.VtC Max (AD518K) Pin Compatible With 118-Type Op Amp Series Mil-Standard Parts Available 8-Pin Plastic Mini-DIP or TO-99 Hermetic Metal Can OBS PRODUCT DESCRIPTION OLE The AD518], AD518K, and AD518S are high speed precision monolithic operational amplifiers designed for applications where slew rate and wide bandwidth are required, but low cost and ease of use are essential. The devices are internally compensated for unity gain applications with a 60° phase margin to insure stability, a minimum unity gain slew rate of 50V/J1.s,and a typical bandwidth of 12MHz. In addition, in inverting applications external feedforward compensation may be added to increase the slew rate to over 1OOVIJ1.s, and nearly double the bandwidth. If desired, settling time to 0.1 % can be reduced to under 1J1.swith a single external capacitor. The AD518's dc performance is consistent with its precision dynamic characteristics. The devices feature offset voltages below 2mV, maximum offset drifts of 15J1.V/C, and offset currents below 50nA max. The high slew rate, fast settling time, ease of use, and low cost of the AD 518 make it ideal for use with DI A and AID converters, as well as active filters, sample-and-hold circuits, and as a general purpose, fast, wideband amplifier. The AD518 is supplied in the TO-99 package. The AD518] and AD518K are specified for operation over the 0 to +70°C temperature range; the AD518S for operation from -55°C to +125°c.

The AD518 offers the user high speed performance and flexibility previously unavailable at low cost. . . . . . . . . TE . . Internal compensation for unity gain applications Capability to increase slew rate to over 1OOVlJ1.sand double the bandwidth by an external feedforward technique . Capability to reduce settling time to under 1J1.sto 0.1% with a single external capacitor . Differential input capability 2. The phase margin of the AD 518, uncompensated at the unity gain crossover frequency, is 60°, providing unconditional stability for all conditions. This conservative phase margin represents a clear improvement over that of the 118 series IC op amps currently available. 3. The static performance of the AD518 is consistent with its excellent dynamic performance, providing offset voltage drift under 15J1.V/oC,CMRR of 80dB, and offset current below 50nA. 4. Every AD518 receives a 24 hour stabilization bake at +150° C to ensure reliability and long-term stability. P.O. Box 280; Norwood, Massachusetts 02062 U.S.A.
