GENERAL DESCRIPTION

The AD8038 (single) and AD8039 (dual) amplifiers are high speed (350 MHz) voltage feedback amplifiers with an exceptionally low quiescent current of 1.0 mA/amplifier typical (1.5 mA maximum). The AD8038 single amplifier in the 8-lead SOIC package has a disable feature. Despite being low power and low cost, the amplifier provides excellent overall performance. Additionally, it offers a high slew rate of 425 V/μs and a low input offset voltage of 3 mV maximum.
