Part Number: AMC7832 Hello TI Team,
I am trying to communicate with an AMC7832 chip with an emulated spi protocol over JTAG.
The boundary scan vectors are changing rather slow in respect to a properly clocked spi protocol but I am able to read registers…
Part Number: AMC7832 Other Parts Discussed in Thread: LM50 , Sir,
In AMC7832 in datasheet it is given like it has internal temperature sensor..and at the end LM50 is used as temperature..can u confirm whether it has internal temperature sensor or not…
Part Number: AMC7832 Other Parts Discussed in Thread: AMC7904 What the funcation about the remote temp sensor about AMC7904?
Can you recommend some AMC7904 compatible temp sensors？
Part Number: AMC7832 Hi,
Please help confirm if it is a must to use seperate LDO for AMC7832 AVDD and AVCC. Is it ok to use digital part power supply to power AVDD and AVCC with some filter caps and FB in middle? What is spec requirement for AMC7832…
Part Number: AMC7832 Hi Supporter
My customer adopt AMC7832 solution. In fact, they need to support negative DAC voltage range to about -5V. AVEE is connedted to -7V, VRANGEA is connected to 2.5V. But they do a wrong connection for AVSSA, AVSSA is connected…
Part Number: AMC7832 Hi,
When my customer use AMC7832, IOVDD should be connected to 3.3V. But they notice that, even IOVDD is NC, AMC7832 could work well in room temperature. And when IOVDD is NC, IOVDD voltage is 3.3V.
I verify this in EVM. When…
Part Number: AMC7832 Hi
When AMC7832 REG 0XC0 bit 0 set to 1, ADC conversion starts. When could we read REG 0X72 BIT 0 to get 1 which means ADC conversion completed? How long does ADC need to finish conversion? Thanks a lot!

David
The AMC7832 has twelve ADC channels with the +/-12.5V input range, denoted as "ADCn" pins in the datasheet. It also has five channels with a +5V input range, denoted as "LV_ADCn".
Thanks!

Hi Tom,
I understand. The level of noise you are seeing is abnormal and I have not seen this issue with the AMC7832. I think you are on the right track with investing the REF_CMP configuration. Please keep me updated if you solve the issue, and feel…
