ESQ-110-14-T-D

By default, DAC_VIO is OFF. However, the VIO is 

ON to make sure EEPROM is read. The VIO is by 

default connected to 3V3 and then based on the 

EEPROM reading, it is switch to the right value. 

This assumes that the BO board has another buffer 

to isolate the EEPROM signals from the DAC 

unless DAC_VIO is present

EXT_VDD-max = 5.5V

EXT_VIO-max = 3.6V

VCC-max = 43V

VSS-max = -21.5V

(VCC-VSS)-max = 43V

This jumper provides a clean 

option to supply low-jitter 

LDAC for high-THD 

applications. When external 

LDAC is not going through 

level translator, VIO must be at 

3V3

This circuit is mainly intended to 

check whether VDD and VIO 

are in the recommended range or 

not.

For MSP430G2, the position of 

MOSI and MISO are 

interchanged. Hence, the resistor 

options are provided

The EXT_LDAC is supplied to 

the uC for SPI or I2C trigger. It 

is also supplied to the DAC. 

When EXT_LDAC is not 

present, a timer is used to 

generate a synchronous LDAC
