EVALUATION BOARD HARDWARE
HARDWARE DESCRIPTION
The
ADG4612
evaluation kit contains a fully fitted PCB.
The evaluation board allows the user to connect the signals that
require switching to the ADG4612 quad SPST switch and control
its operation by using the on-board links or by applying the
correct control signals to the appropriate connectors. The
signals present at the pins of the ADG4612 can be monitored
through the test points provided on the board.
POWER SUPPLIES
To operate the ADG4612 evaluation board, you must provide an
external power supply connected to the J2 power block.
The ADG4612 has 3 V to +16 V and dual ±3 V to ±5.5 V
operation and is fully specified for ±5 V, +5 V, and +12 V.
SWITCH CONTROL CONNECTORS
The ADG4612 offers a standard CMOS/LVTTL parallel interface
consisting of four IN inputs. The IN1, IN2, IN3, and IN4 input
pins control the switch state and operation mode of the ADG4612.
The evaluation board allows the user to control the signals
required to set the logic levels applied to these pins by using
the LK1, LK2, LK3, and LK4 links as described in Table 1, or by
applying external signals to the SMB connectors, IN1 through
IN4, as described in Table 2.
