The ADA4897-2-KGD1 is a high speed amplifier with rail-torail input and output that operates on low supply voltages and
is optimized for high performance and a wide dynamic signal
range. The ADA4897-2-KGD has low noise (1 nV/√Hz,
2.8 pA/√Hz) and low distortion (−93 dBc at 1 MHz). In
applications that use a fraction of or the entire input dynamic
range and require low distortion, the ADA4897-2-KGD is an
ideal choice.
APPLICATIONS
Low noise preamplifiers
Ultrasound amplifiers
PLL loop filters
Active filters
ADC drivers
Low voltage instrumentation
DAC buffers
Many rail-to-rail input amplifiers have an input stage that switches
from one differential pair to another as the input signal crosses a
threshold voltage, which causes distortion. The ADA4897-2-KGD
has a unique feature that allows the user to select the input
crossover threshold voltage through the DISABLEx pin. This
feature controls the voltage at which the complementary
transistor input pairs switch. The ADA4897-2-KGD also has
intrinsically low crossover distortion. With its wide supply
voltage range (3 V to 10 V) and wide bandwidth (230 MHz),
the ADA4897-2-KGD amplifier is designed to work in a variety
of applications where speed and performance are needed on low
supply voltages. The ADA4897-2-KGD has a disable mode that
is controlled via the DISABLEx pin.
The ADA4897-2-KGD is rated to work over the industrial
temperature range of –40°C to +125°C.
Additional application and technical information can be found
in the ADA4897-2 data sheet.
