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…
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…

Part Number: DAC8775 Other Parts Discussed in Thread: TIPD216 , Hello,
My design consist of DAC8775, setup in the same manor TIPD216 board (with use of internal buck boosts) with an input power of 24VDC. Internal DVDD is disabled, and 3.3V is connected…
Hello,
If I am understanding correctly, you are testing the Vout/Iout combined node against this transient test. Is that correct? We have a protection circuit that includes TVS, clamping diodes, and current limiting resistors that provides immunity against…
Hi Alex,
R1 and R2 form low pass filters with C4, C6 and C3, C5 respectively. These filter the output of the buck-boost converter (Vpos, Vneg) to reduce the output voltage ripple.
R4, R5, and R6 are current limiting resistors that limit the current into…
Howdy Tokumoto-san and Happy New Year!
I'm glad I could help. There is one additional change that would improve and benefit your design, and that is to add another 15 ohm resistor at IOUT pin. Currently, in you design, the internal ESD diodes connected…
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 …
Lakshmanan,
DAC80508 and DAC81408 which you and Uttam have discussed in this thread are our most modern 16-bit, 8-CH, SPI interfaced DACs. In that regard they will be offering the best performance in terms of offset, gain, and INL errors as well as drift…
