GENERAL DESCRIPTION

The EVAL-ADG2412EBZ is the evaluation board for the ADG2412. The ADG2412 contains four independent single-pole/single-throw (SPST) switches. The ADG2412 switches turn on with Logic 1.
Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends from VSS to VDD – 2 V. When the switches are open, signal levels up to the supplies are blocked. The ADG2412 does not have a VL pin. The digital inputs are compatible with 1.8 V logic inputs over the full- operating supply range. The on-resistance profile is very flat over the full-analog input range, which ensures good linearity and low distortion when switching audio signals.
Figure 1 shows the EVAL-ADG2412EBZ evaluation board. The ADG2412 is located in the center of the evaluation board and wire screw terminals are provided to connect to each of the source and drain pins. Three screw terminals power the device and a fourth terminal provides users with a defined digital logic- supply voltage, if required. Alternatively, the digital logic-supply voltage can be supplied from the ADP7142 that is on the board.

Full specifications on the ADG2412 are available in the ADG2412 data sheet available from Analog Devices, Inc., and must be con- sulted with this user guide when using the EVAL-ADG2412EBZ evaluation board.

POWER SUPPLIES

Connector P1 provides access to the supply pins on the ADG2412. VDD, GND, and VSS on P1 link to the appropriate pins on the ADG2412. For dual-supply voltages, the EVAL-ADG2412EBZ eval- uation board can be powered from ±13.5 V to ±16.5 V, or from ±4.5 V to ±5.5 V. For single-supply voltages, the GND and VSS terminals must be connected and VDD between 10.8 V to 13.2 V. Additionally, 5 V from the ADP7142 regulator can be supplied to INx logic pins of the ADG2412 via links IN1, IN2, IN3, and IN4. To use the 5 V from the ADP7142 for the logic inputs, then use the default setting of R5 populated and R6 not inserted. If there is a wish to supply a custom logic voltage via the IN1, IN2, IN3, and IN4 headers, then EXT_VL on P1 can be supplied with a suitable logic voltage. To use EXT_VL on P1, do not insert R5 and populate R6.

INPUT SIGNALS

Screw connectors, P2, P3, P4, and P5 are provided to connect to both the source and drain pins of the ADG2412. Additional
Subminiature Version B (SMB) connectors are available to connect cables to the source and drain pins.
Each trace on the source and drain side includes two sets of 0603 pads, which can place a load on the signal path to ground. A 0
Ω resistor is placed in the signal path and can be replaced with a user- defined value. The resistor combined with the 0603 pads can create a simple RC filter.

LINK OPTIONS

Several link options are provided on the EVAL-ADG2412EBZ evalu- ation board. The functions of these link options are described in Table 1.

Table 1. Link Options

Link Number Options

IN1, IN2, IN3, IN4	A = switch closed	B = switch open

DIGITAL INTERFACE OPTIONS

The digital interface of the ADG2412 can either be controlled manually using the IN1, IN2, IN3, and IN4 link headers or accessed by using the J1, J2, J3, and J4 SMB connectors. To use the SMB connectors, remove the IN1, IN2, IN3, and IN4 link headers.
Connecters P6, P7, P9, and P10 can also be used with a controller board such as the SDP-K1 or Arduino. If a controller board is used to control the ADG2412, remove the IN1, IN2, IN3, and IN4 link headers.

ESD Caution

ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality.
