PRODUCT DESCRIPTION
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,

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
unconditional stability for all conditions. This conservative
phase margin represents a clear improvement over that of
the 118 series IC op amps currently available.
currents below 50nA max.
3. The static performance of the AD518 is consistent with its
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
excellent dynamic performance, providing offset voltage
drift under 15J1.V/oC,CMRR of 80dB, and offset current
below 50nA.
4. Every AD518 receivesa 24 hour stabilization bake at
+150° C to ensure reliability and long-term stability.
AD518K are specified for operation over the 0 to +70°C
temperature range; the AD518S for operation from -55°C to
+125°c.
