GENERAL DESCRIPTION

This data sheet describes the evaluation board for the ADG788,

a triple SPDT switch packaged in a compact 4 mm × 4 mm body,

20-lead LFCSP package. The switches are designed using an

enhanced submicron CMOS process to provide optimal

performance in terms of on resistance, bandwidth, and power

dissipation. The excellent on resistance flatness makes the

ADG788 ideal for a wide range of applications, including data

and audio-video switching. Each SPDT switch can be

individually controlled using a 1-wire parallel interface.

The evaluation board supports both single- and dual-supply

operation and comes fitted with connectors that allow the user

to evaluate the performance of the ADG788 with minimum effort.

The operation of the switches is controlled using the on-board

links or by applying external control signals to the appropriate

connectors.

The data sheet for the ADG788 device is available from Analog

Devices, Inc. It contains all the information regarding operation

of the device, and it should be consulted in conjunction with

this data sheet when using the evaluation board.

EVALUATION BOARD HARDWARE

The ADG788 evaluation board kit contains the following:

• A fully fitted printed circuit board

• A CD containing the ADG788 product data sheet and the

evaluation board data sheet

The evaluation board allows the user to connect the signals that

require switching to the ADG788 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 ADG788 can be monitored using the test point

provided on the board.

The following sections describe the function of all connectors

and links.

POWER SUPPLY

To operate the ADG788 evaluation board, the user must provide

an external power supply connected to Power Block P1. The

supply voltage range is 1.8 V to 5.5 V for single-supply operation

and ±2.5 V for dual-supply operation. The user can select single-

supply operation or dual-supply operation using Link J23, as shown

Table 1.

Table 1. Link J23 Configuration

Position Operation Mode

A Single-supply operation

B Dual-supply operation (default configuration)

SWITCH CONTROL

The four input pins, IN1, IN2, IN3, and IN4, control the opera-

tion of the ADG788. Link J8, Link J9, Link J12, and Link J13

control the logic levels applied to these pins and allow the user

to drive these pins with external signals applied to Connector J5

and Connector J11 (the signals have 50 Ω on-board termination

resistors to GND).

Table 2 describes the configuration achieved

for each position of these links.
