AD8039 Low Power, 350 MHz Voltage Feedback Amplifiers

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.

The Analog Devices, Inc., proprietary XFCB process allows low noise operation (8 nV/√Hz and 600 fA/√Hz) at extremely low quiescent currents. Given a wide supply voltage range (3 V to 12 V), wide bandwidth, and small packaging, the AD8038 and AD8039 amplifiers are designed to work in a variety of applications where power and space are at a premium.

The AD8038 and AD8039 amplifiers have a wide input common-mode range of 1 V from either rail and swing to within 1 V of each rail on the output. These amplifiers are optimized for driving capacitive loads up to 15 pF. If driving larger capacitive loads, a small series resistor is needed to avoid excessive peaking or overshoot.

The AD8039 amplifier is available in a 8-lead SOT-23 package, and the single AD8038 is available in both an 8-lead SOIC and a 5-lead SC70 package. These amplifiers are rated to work over the industrial temperature range of −40°C to +85°C.
