Part Number: DAC8775EVM Other Parts Discussed in Thread: TIPD215 Hello,
I am using DAC8775EVM with the GUI tool for configuring 4-20mA. I am unable to get and current at the output. I have used the below jumper settings.

JP11 - Installed…
Part Number: LM5166 Other Parts Discussed in Thread: DAC8775 , LM5165 , , TIPD215 Hi,
We are using LM5166QDRCTQ1 in one of our design with DAC8775 and presently LM5166QDRCTQ1 is shortage and needed very few qty for proto but still won't available, There…
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…
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…
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…
Zhou,
Typically high-end AO Modules will implement a two-point calibration scheme at room temperature and/or over temperature to improve accuracy. Between reference initial accuracy, signal chain initial accuracy, and system-wide drift figures this…

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…
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…
