Part Number: AMC7834
Hi,
I’m using BIAS controller AMC7834 to bias RF driver amplifiers and power amplifiers in my design.
I have some doubts regarding the same:
1) I’m not using Auxiliary DAC outputs – AUXDAC (1, 2, 3, and 4). Shall I leave them…

Part Number: AMC7834 Tool/software: AMC7834 is not setting the DAC. whenever I turn off and on the board, same code but not working sometimes . when checked for device id it is not coming. Why? Anyone faced this? Even though IC is working other times…
Part Number: AMC7834 Tool/software: Hi team,
I'd like to check the robustness of the AMC7834 when exposed to a short transient.
The CS, CSLK, SDI pins can experience a voltage swing from -1.0V min. or 4.0V max. lasting approximately 60ns under IOVDD…
Part Number: AMC7834 Tool/software: I want to read from ADC in autonomous conversion. I have enabled in 0x02 register. In mux register (0x12) written as 0x0010 and tried to read from the following register 0x24 but does not returned the correct value…
Part Number: AMC7834 Tool/software: Hi team,
When Address (0x17) CLAMP Configuration bit1 (DAC34-CLAMP) is set to 0, IOVDD amplitude changed significantly. In the customer's system, only DAC4 is floating. Could you suggest any possible reasons to change…
Part Number: AMC7834 Tool/software: Hi team,
With respect to SPI communication of AMC7834IRTQR, my customer found that if the last bit is 'H', it holds 'H' even after the one frame is sent or read.
Please find the waveform below.
Could you let…
Part Number: AMC7834 Tool/software: Hi team,
My customer is evaluating AMC7834 on the prototype board. He's struggling to read out current sense registers on address 0x28 - 0x30.
The register configuration below is set to default.
