Part Number: DAC8775EVM Other Parts Discussed in Thread: TIPD216 , DAC8775 , Tool/software: Hello TI team.
In the reference design for DAC8775, TIPD216 DAC8775EVM, and datasheet it is suggested that the DAC8775 will pass IEC61000-4 test. In the TIPD216…
Part Number: DAC8775 Other Parts Discussed in Thread: TIPD216 , , DAC8760 , TVS3301 Tool/software: Hi, we designed a circuit with DAC8775 following the TI EVM wiring diagrams: https://www.ti.com/tool/TIPD216 This EVM has been tested to pass EMC tests…
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…
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…
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…
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…
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…
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…
