GND
Ground. Connect to the boards ground plane using low-inductance layout techniques.
2
OUT_A
Attenuator A Output. Internally matched to 50I over the operating frequency band. This pin,
if used, requires a DC block. If this attenuator is not used, the pin can be left unconnected.
5, 13, 32
V
CC
Power Supply. Bypass to GND with capacitors and resistors as shown in the Typical
Application Circuit.
8
IN_A
Attenuator A Input. Internally matched to 50I over the operating frequency band. This pin,
if used, requires a DC block. If this attenuator is not used, the pin can be left unconnected.
11
CTRL
Analog Attenuator Control Input. V
CC
 must be present unless using a current-limiting resis-
tor, as noted in the Applications Information section. Limit voltages applied to this pin to a
+1.0V to +4.0V range with V
CC
 present to ensure device reliability.
29
OUT_B
Attenuator B Output. Internally matched to 50I over the operating frequency band. This pin,
if used, requires a DC block. If this attenuator is not used, the pin can be left unconnected.
35
IN_B
Attenuator B Input. Internally matched to 50I over the operating frequency band. This pin,
if used, requires a DC block. If this attenuator is not used, the pin can be left unconnected.

EP
Exposed Pad. Internally connected to GND. Solder evenly to the boards ground plane for
proper operation.
