APPLICATIONS INFORMATION
BASIC CONNECTIONS
Figure 31 shows the basic connections for operating the
ADL5565. Apply a voltage between 3 V and 5 V to the VCC pins,
and decouple each supply pin with at least one low inductance,
0.1 μF surface-mount ceramic capacitor, placed as close as
possible to the device. Also, decouple the VCOM pin (Pin 9)
using a 0.1 μF capacitor.
The gain of the part is determined by the pin-strappable input
configuration. When Input A is applied to VIP1 and Input B is
applied to VIN1, the gain is 6 dB (minimum gain, see Equation 1
and Equation 2). When Input A is applied to VIP2 and Input B

is applied to VIN2, the gain is 12 dB (middle gain). When Input A
is applied to both VIP1 and VIP2 and Input B is applied to both
VIN1 and VIN2, the gain is 15.5 dB (maximum gain).
Pin 1 to Pin 4, Pin 10, and Pin 11 are biased at 1/2 VCC above
ground and can be dc-coupled (if within the specified input or
output common-mode voltage levels) or ac-coupled as shown in
Figure 31.
To enable the ADL5565, the ENBL pin must be pulled high.
Pulling the ENBL pin low puts the
reducing the current consumption to 5 mA at ambient.
