At power-up, my LTC2668 initializes all channels to 0V. That's correct by my setting of MSP0 = 5V, MSP1 = 5V and MSP2 = 0. According to Table 4, that selects 0-10V operation with initial outputs at 0V. This condition persists for maybe several seconds…
I am using LTC2668 DAC that works fine in prototype, The problem we are experiencing is that occasionally during electrical noise it locks up in field side, and begin to analog output locked up. unless I power down than power up the system.
If this device…
Hi,
I have DC2025A-A demo board for 16 bit LTC2668. The board has the option to be used with QuickEval with extra boards but I don't have them. According to the manual, DC2025A can be used with micro controllers by using SPI. My problem is I cannot get…
The MSPAN pins internally are just gates so they can be pulled to GND or AVP through 4.7K resistors. That isn't a problem.
Hello,
I designing a power supply +5V and -/+15V with ADP1613 and ADP1614 (+/-15V) for ADAS3022 and DAC LTC2668 from Linear Technology. I use ADP1613 to generate 6.5V from 5V input, then I use LDO to get clean 5V for analog circuit. After doing measurements…
