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. There…
Thanks, Joseph, The multimeter series fuse had blown. Things are once again working fine on the EVM.
But I am unable to see the output on TIPD215 board. I have created a copy of TIPD215. Please find the attached schematic. I am using the same SPI code…
Hi Arief,
https://www.ti.com/tool/TIPD215
Can you please see the Bill of material i the above link.
They too uses LM5166QDRCTQ1
I am still confused with this part i.e., LM5166QDRCTQ1
Regards,
Amit Jain
Amit,
First, along with the datasheet, there are a couple of other documents you can use as templates for your schematic. First, the EVM can be used as a template for a schematic. The EVM schematic should operate to the specifications shown in the datasheet…
Eddie,
If the POC bit is set to 1, then the IOUT_x and VOUT_x are set to HIZ at power up, hardware and software reset. It should not affect the output when the device is in operation.
For VOUT, adding an extra 100kΩ as load should not be a problem. However…

Part Number: DAC8775 Other Parts Discussed in Thread: TIPD215 Hi,
I'm working on a project where I want to use the DAC8775 for two analog outputs controlled through SPI interface. I have used TIPD215 as a reference design but I have a few questions.…
Part Number: DAC8775 Other Parts Discussed in Thread: TIPD216 , TIPD215 Hi,
DAC8775 datasheet shows that IOUT TUE is higher than 0.1% refer to external reference. Is there other way to improve DAC8775 IOUT error to be less than 0.1% refer to absolute …
Howdy Namita,
Thanks for posting and welcome to the e2e forums! You are correct in your assessment, you can use the DAC7760 device, but before diving into the devices that provide this current output may I ask a few questions. What are the resolution…
