2.1.2 Jumper Definitions

The jumpers must be connected properly to operate the DAC80502-01EVM. Table 3-1 provides the details of the configurable jumper settings of the DAC80502-01EVM. Figure 3-2 shows the default jumper connections on the board.

Table 2-1 DAC80502-01EVM Jumper Definitions
DesignatorNamePositions
J1FTDI DIS

SHORT 1-2 – FTDI communication is disabled.

OPEN – FTDI communication is enabled (default).

J5

I2C-SPI

SHORT 1-2 – SPI2C connected to ground for SPI communication (default).

SHORT 2-3 – SPI2C connected to VDD for I2C Configuration.

OPEN – SPI2C floating, invalid position.

J6

VDD SEL

SHORT 1-2 – VDD is connected to USB 5 V (default).

SHORT 3-4 – VDD is connected to on-board 3.3 V.

OPEN – VDD is externally powered.

J8

SDA - PICO

SHORT 1-2 – Connects the DAC80501 and the DAC80502 SDIN/SDA pins to the FTDI PICO pin for SPI mode (default).

SHORT 2-3 – Connects the DAC80501 and the DAC80502 SDIN/SDA pins to the FTDI SDA pin for I2C Mode.

OPEN – Open if external communication is used.

J10

U2 VREF = 2.5V

SHORT 1-2 – Connects the DAC80502 VREFIO pin to the on-board 2.5-V reference.

Make sure the internal reference is powered off before closing this jumper.

OPEN – Open if internal reference or external reference via J9 is used (default).

If an external reference is used, then turn off the internal reference.

J11

SCL - SCLK

SHORT 1-2 – Connects the DAC80501 and the DAC80502 SCLK/SCL pins to the FTDI SCLK pin for SPI mode (default).

SHORT 2-3 – Connects the DAC80501 and the DAC80502 SCLK/SCL pins to the FTDI SCL pin for I2C Mode.

J12

U1 VREF = 2.5V

SHORT 1-2 –Connects the DAC80501 VREFIO pin to the on-board 2.5-V reference.

Make sure the internal reference is powered off before closing this jumper.

OPEN – Open if internal reference or external reference via J9 is used (default).

If an external reference is used, then turn off the internal reference.

J13

U1 A0 Select

SHORT 1-2 – DAC80501 SPI configuration (default).

SHORT all else – DAC80501 I2C configuration, see Table 3-7 for jumper configurations.

OPEN – Open if external communication is used.

J14

U2 A0 Select

SHORT 1-2 – DAC80502 SPI configuration (default)

SHORT all else – DAC80502 I2C configuration, see Table 3-7 for jumper configurations.

OPEN – Open if external communication is used.

J19

RST Select

SHORT 1-2 – DAC80502 RSTSEL pin is connected to VDD.

OPEN – DAC80502 RSTSEL pin is connected to GND (default).
