The ADG854 is soldered onto the EVAL-ADG854EBZ evaluation board in a tiny 1.3 mm × 1.6 mm ultrathin LFCSP located in the center of the board and is designated as U1. Full-featured evaluation board for the ADG854 On-board audio connectors GENERAL DESCRIPTION CONNECTING SIGNALS TO THE BOARD This user guide describes the EVAL-ADG854EBZ evaluation board for the ADG854, which is a low voltage CMOS device that contains two independently selectable, single-pole, doublethrow (SPDT) switches. The ADG854 offers an ultralow on resistance of less than 1 Ω over the full temperature range. The EVAL-ADG854EBZ evaluation board is fitted with three audio connectors that allow switching between audio devices. All signals applied to the switch can be monitored using the test points provided on the evaluation board. 10650-001 EVAL-ADG854EBZ EVALUATION BOARD Figure 1.

For full details on the ADG854, see the ADG854 data sheet, which should be consulted in conjunction with this user guide when using these evaluation boards. The EVAL-ADG854EBZ evaluation board allows the user to switch between two audio sources or to switch an audio source between two speakers by using the on-board jumpers or by applying the correct control signals to the appropriate connectors. POWER SUPPLY The ADG854 can operate from a 1.8 V to 5.5 V single supply and is fully specified for 5.5 V and 3.3 V supply operation. SWITCH CONTROL CONNECTORS The ADG854 device offers a standard CMOS/LVTTL parallel interface consisting of two IN inputs. The IN1 and IN2 input pins control the switch state and operation mode of the ADG854. The EVAL-ADG854EBZ evaluation board allows the user to control the signals required to set the logic levels applied to these pins by using the L2 and L3 links as described in Table 1 or by applying external signals to the SMB connectors, IN1 and IN2, as described in Table 2. To control the ADG854 using the SMB connectors, L2 and L3 must be set to Position B. Note that there are 51 Ω termination resistors at the IN1 and IN2 SMB connectors to GND. Table 1.
