ADL5565
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 ADL5565 in sleep mode,
reducing the current consumption to 5 mA at ambient.
