Part Number: DAC8775 Hi team,
We used DAC8775. For /LDC signal, we use it in Synchronous Mode now.
DAC8775 Datasheet said, if certain delay “SYNC rising edge->LDAC falling edge” 33ns is not met, invalid data will be loaded. How about the invalid data…
Part Number: DAC8775 Hi team,
We are currently using DAC8775 and the Reset pin remains high when powered on. When I read the Device ID, it is 0x0003. Why does the value of this register change? Will the registers of DAC8775 be confused when the Reset…
Part Number: DAC8775 We are using DAC8775 in our new product that is under development. We have the following questions with this device:
1. With the range of 0 ~20mA of this device, is there any offset at the low end ( 0mA ) ? if it might have some offset…
Part Number: DAC8775 Hi TI!
We are currently validating our HW platform and want to verify the SPI and logic interface. Rise and Fall times are not specified for the SPI and logic outputs nor the rise/fall time requirements for the SPI and logic inputs…
Part Number: DAC8775 Other Parts Discussed in Thread: DAC8760 Hi Experts,
As you know each channel of DAC8775 can work at either current output mode or voltage output mode. And current and voltage output has separate pinouts. I am wondered can each channel…
Part Number: DAC8775 Hi,
I want to use the DAC8775 with external +12V and -12V supplies.
A line in the datasheet has me worried:
"Note that, VNEG_IN_x is internally shorted to PBKG when the negative arm of Buck-Boost converter is not enabled."…
Hi Joseph,
Your explaination confirms my observation. Indeed, I set every channel with the slew rate. No wonder the instant read back did not match my writing value.
Thank you very much!

Hi Kai, What DAC output ranges are the customer observing this 75 mV issue? Can they verify that their negative supply and reference voltage are stable/correct during this event? If this was only tested on one unipolar range, can they check using a bipolar…
Part Number: DAC8775 Hello,
My customer has some questions of VOUT ripple of DAC8775.
The below is from the datasheet(SLVSBY7) on P12.
They want to confirm the condition of this parameter.
1. Is an optional RC filter (like the below) used in this case…
