GENERAL DESCRIPTION

The EVAL-ADG1634LEBZ is the evaluation board for the ADG1634L. The ADG1634L contains four independent single-pole, double-throw (SPDT) switches. 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 ADG1634L is both 1.2 V and 1.8 V JEDEC standard compliant.
Figure 1 shows the EVAL-ADG1634LEBZ in a typical evaluation setup. The EVAL-ADG1634LEBZ is located in the center of the evaluation board. Eight test points are included to connect to each of the source pins. Subminiature Version B (SMB) sockets are included for the drain inputs. Three screw terminals power the device. A 5-pin header is provided for user defined digital voltage, if required.
Full specifications on the ADG1634L are available in the ADG1634L data sheet available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using the EVAL-ADG1634LEBZ.

POWER SUPPLY
Connector P1 provides access to the supply pins on the ADG1634L. VDD, GND, and VSS on P1 link to the appropriate pins on the ADG1634L. For dual-supply voltages, the EVALADG1634LEBZ can be powered at ±5 V. For single-supply voltages, the GND and VSS terminals must be connected and power the EVAL-ADG1634LEBZ with 5 V or 12 V. Additionally, 1.1 V to 1.95 V is supplied to the VL pin of the ADG1634L.
LINK HEADERS
A number of link options are provided on the EVAL-ADG1634LEBZ that must be set for the required operating conditions before using. Table 1 shows the summary of the link headers and how they are used on the EVAL-ADG1634LEBZ. The functions of these link options are described in detail in Table 2.
Table 1. Link Header Descriptions

Link	Position	Description
JP13 to JP17	A B	VL GND

Table 2. Link Header Functions

Link	Function
JP13 to JP17	This link selects the source of the INx voltage supplied to the ADG1634L. Position A selects VL from P2. Position B selects 0 V or GND.

SMB CONNECTORS

The parallel interface of the ADG1634L is controlled manually using the link headers of JP13 to JP17, or it can be accessed using the SMB connectors, IN1 to IN4. To use the SMB connectors, remove the JP13 to JP17 link headers.

INPUT SIGNALS

Four screw connectors, P3, P4, P5, and P6, are provided to connect to both the source and drain pins of the ADG1634L. 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 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.
