GENERAL DESCRIPTION

The EVAL-ADG1412LEBZ is the evaluation board for the ADG1412L. The ADG1412L contains four independent SPST switches, and these switches are turned on with Logic 1. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.
An external VL supply pin provides logic-control flexibility for lower logic controls. The ADG1412L is both 1.2 V and 1.8 V JEDEC standard compliant.
Figure 1 shows the EVAL-ADG1412LEBZ in a typical evaluation setup. The EVAL- ADG1412LEBZ is located in the center of the evaluation board. Four test points and Subminiature Version B (SMB) sockets are provided to connect to each of the source pins. Three screw terminals power the device. A 5-pin header is provided for the user-defined digital voltage, if required.
Full specifications on the ADG1412L are available in the ADG1412L data sheet available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the EVAL-ADG1412LEBZ.

POWER SUPPLY
Connector P1 provides access to the supply pins on the ADG1412L Datasheet and Product Info | Analog Devices. VDD, GND, and VSS on P1 link to the appropriate pins on the ADG1412L. For dual-supply voltages, the EVALADG1412LEBZ can be powered at ±15 V. For single-supply voltages, the GND and VSS terminals must be connected and power by the EVAL-ADG1412LEBZ with 5 V or 12 V. Additionally, 1.1 V to 1.95 V is supplied to the V pin of the ADG1412L.
LINK HEADERS
A number of link options are provided on the EVAL-ADG1412LEBZ that must be set for the required operating conditions before using. Table 1 summarizes the link headers and how these headers are used on the EVAL-ADG1412LEBZ. The functions of these link options are described in detail in Table 2.

Position A selects VL from P2.
Position B selects 0 V or AGND.

SMB CONNECTORS
The parallel interface of the ADG1412L is controlled manually using the link headers of JP9 to JP12, or it can be accessed using the SMB connectors, IN1 to IN4. To use the SMB connectors, remove the JP9 to JP12 link headers.
INPUT SIGNALS
The 2-pin terminal blocks, P3, P4, P5, and P6, are provided to connect to both the source and drain pins of the ADG1412L.
Additional SMB connector pads are available if extra connections are required.
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.
