The AD8038 (single) and AD8039 (dual) amplifiers are high speed The AD8039 amplifier is available in a 8-lead SOT-23 package, (350 MHz) voltage feedback amplifiers with an exceptionally low and the single AD8038 is available in both an 8-lead SOIC and a quiescent current of 1.0 mA/amplifier typical (1.5 mA maximum). 5-lead SC70 package. These amplifiers are rated to work over The AD8038 single amplifier in the 8-lead SOIC package has a the industrial temperature range of −40°C to +85°C. disable feature.
