ADL5562
APPLICATIONS INFORMATION
BASIC CONNECTIONS
Figure 31 shows the basic connections for operating the ADL5562.
VCC should be 3.3 V with each supply pin decoupled with at least
one low inductance surface-mount ceramic capacitor of 0.1 uF
placed as close as possible to the device. The VCOM pin (Pin 9)
should also be decoupled using a 0.1 uF 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 the gain
vs. load equations). 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 VIP1 and VIP2 and Input B is applied
to VIN1 and VIN2, the gain is 15.5 dB (maximum gain).
Input Pin 1 to Input Pin 4, Output Pin 10, and Output 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 ADL5562, the ENBL pin must be pulled high.
Pulling the ENBL pin low puts the ADL5562 in sleep mode,
reducing the current consumption to 3 mA at ambient.
