INTRODUCTION
This evaluation board is for the AD5535, 32-channel, 14-bit
high voltage output DAC. The AD5535 contains 32 14-bit
DACs in one package. They have a maximum output voltage
span of 200 V derived from a reference voltage of 4.096 V.
The AD5535 has a serial SPI interface that is compatible with
SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
The DAC outputs are updated on reception of new data into the
DAC registers.
See the
AD5535 data sheet for product details.
AD5535 EVALUATION BOARD POWER SUPPLIES
The following external supplies must be provided:
• 5 V between the DV
CC
and DGND inputs for the digital
supply of the AD5535.
• 5 V between the AV
CC
and AGND inputs for the analog
supply of the AD5535.
• −5 V between the V− and AGND inputs for the analog
supply of the AD5535.
• +5 V between the V+ and AGND inputs for the analog
supply of the AD5535.
• 210 V between the V
PP
and AGND inputs for the analog
supply of the AD5535.
Both AGND and DGND inputs are provided on the board. The
AGND and DGND planes are connected at one location close
to the AD5535. It is recommended not to connect AGND and
DGND elsewhere in the system to avoid ground loop problems.
Each supply is decoupled to the relevant ground plane with
10 μF and 0.1 μF capacitors. Each device supply pin is again
decoupled with a 10 μF and 0.1 μF capacitor pair to the relevant
ground plane.

LINK OPTIONS
The link options on the evaluation board should be set for the required operating setup before using the board. The functions of the link
options are described in
Table 1.
Table 1. Link Options
Link No. Function
LK1 This link selects the voltage reference source for the AD5535:
• Position A selects an external source via J3 as the voltage reference.
• Position B selects the on-board 4.096 V reference as the voltage reference source, resulting in a full-scale output
value of 200 V.
• Position C selects a divided down value of the on-board reference as the voltage reference source (See LK2).
LK2 This link selects one of three divided down voltage reference values:
• Position A selects a value of 3.072 V, resulting in a full-scale output value of 154 V.
• Position B selects a value of 2.048 V, resulting in a full-scale output value of 102 V.
• Position C selects a value of 1.024 V, resulting in a full-scale output value of 51 V.
LK3 This link selects the state of the TEST pin:
• In the on position, TEST is connected to DGND, and therefore all DACs are updated on loading of any one DAC.
• In the off position, TEST is connected to DV
CC,
and therefore only the addressed DAC is updated.
LK4 This link connects the two 5 V (V+ and AV
CC
) input connectors together:
• In the on position, the two connectors are connected together and only one requires a power supply connection.
• In the off position, the two connectors are not connected together and require individual power supply connections.
