The AD8027/AD80281 is a high speed amplifier with rail-to- rail input and output that operates on low supply voltages and is optimized for high performance and wide dynamic signal range. The AD8027/AD8028 has low noise (4.3 nV/Hz</a>, 1.6 pA/Hz</a>) and low distortion (120 dBc @ 1 MHz). In appli-cations that use a fraction of or the entire input dynamic range and require low distortion, the AD8027/AD8028 is an ideal choice.
Many rail-to-rail input amplifiers have an input stage that switches from one differential pair to another as the input sig- nal crosses a threshold voltage, which causes distortion. The AD8027/AD8028 has a unique feature that allows the user to select the input crossover threshold voltage through the SELECT pin. This feature controls the voltage at which the complementary transistor input pairs switch. The AD8027/ AD8028 also has intrinsically low crossover distortion.
With its wide supply voltage range (2.7 V to 12 V) and wide bandwidth (190 MHz), the AD8027/AD8028 amplifier is designed to work in a variety of applications where speed and performance are needed on low supply voltages. The high per-formance of the AD8027/AD8028 is achieved with a quiescent
current of only 6.5 mA/amplifier typical. The AD8027/AD8028 has a shut down mode that is controlled via the SELECT pin.
The AD8027/AD8028 is available in SOIC-8, MSOP-10, and SOT-23-6 packages. They are rated to work over the industrial temperature range of 40°C to +125°C.
