Part Number: DAC8760 Other Parts Discussed in Thread: OPA192 , , , TIPD119 Hi, I have some questions, could you please help me? 1. Unused HART-IN Do I have to tie HART-IN pin to GND through a 22 nF capacitor or can I leave it floating? 2. Does the DAC…
Hello Richard,
I'll respond to all the previous questions below here. The reference design you mentioned (TIPD119) was designed to show how to functional combined analog output pin hence the lack of protection components.
There is an another reference…
HI Lucas,
In DAC8750,
Is it must to connect HART-IN pin to FSK modulation? or Can we connect it to ground through 22nF as shown in reference design is the TIPD119 .
What is the termination method of ALARM and CLR pin if it not used?
Regards…
Part Number: DAC7760 Other Parts Discussed in Thread: TIPD119 , TIPD153 Hi team,
Please let me ask you two questions about DAC7760.
Q1)If HART interface is not used,can the HART-IN pin be left floating? *In the TIPD119, 22nF capacitor is connected…
Hi Rohidas,
What is the condition of the output when the device is overheating? Does the device get damaged?
The thermal pad should be connected to AVSS as your schematic indicates.
I also noticed that you are tying Vout and Iout together. When…
Nikita,
I believe you are correct that there isn't any schematic / reference design that is exactly like what you're asking for.
That said, I think TIPD119 comes pretty close. The only modification you would need to make in order to make TIPD119…
Hi David,
The primary reason for isolating in the digital domain is that it is relatively easy to isolate a digital signal and reproduce it accurately without any issues than an analog signal directly. Isolating an analog channel directly will pose…
Hi John,
Take a look at the DAC8760, or a DAC + XTR combination like the design shown in TIPD155 .
We also have a few reference designs featuring the DAC8760. Take a look at TIPD119 and TIPD153 .
HI Shibin,
As Kai has mentioned, on the current transmitter application, the main issue with the Howland Current source configuration is that could be sensitive to capacitive/inductive load and will likely become unstable while driving a long cable…
Hi! Kevin,
Thanks for your support. I'll check TIPD119. Another issue: DAC8760 reuires a SPI, ADS5560 requires a SPI for programming, ADS5560 also requires CMOS parralel output or DDR LVDS output, refer to ADS5560 datasheet, how are GPIOs on Launchxl…
