Part Number: AMC7834 Hi Expert,
In the datasheet of AMC7834, the grounds of the analog circuit and the digital circuit are separated (first picture), but they are finally connected together at a unknown position (second picture). Third picture is our circuit…
Part Number: AMC7834 Hi team,
My customer is evaluating PA control circuit with AMC7834 and they would like to consult with you.
They would like to have one port DAC for -3.4v use only. Would you recommended for this requirement?
May I know the full…
Part Number: AMC7834 Hi expert,
May I know what's the measure points for t(OZD)? I thought it's the time to measure the delay between the CS signal falling edge and the SDO signal transition from tri-state to driven.
However, from the timing diagram…
Part Number: AMC7834 Hi,
Good Day.
The customer is using AMC7834 in their new product for PA biasing and monitoring.
According to the datasheet, the AMC7834 is monitoring AVSS and can put the DAC an AUXDAC output to clamping status if AVSS is out of range…
Part Number: AMC7834 Hi Team, Page 10 of the AMC7834 datasheet shows the DAC load current at +/-10mA minimum. Does this imply that the DAC won't conduct unless it sources/sinks atleast +/-10mA? Our customer intends to source/sink around 5mA (due to load…
Part Number: AMC7834 Hi Experts,
Good day. I am posting this concern on behalf of the customer.
Below is the customer's full transcript of the inquiry.
"There's an existing question: AMC7834: Thermal pad connection to ground vs Vss on the forum. I…
Part Number: AMC7834 After power on AMC chip we are doing read operation for the register(0x0C). When giving the command as per the spec (SDO) 0x8C(8 denotes the read operation and C is the address) is given to chip but device is not responding.
We are…
Part Number: AMC7834 Hello
For the AMC7834 the datasheet ( https://www.ti.com/lit/ds/symlink/amc7834.pdf ) lists two different package/footprint designs - RTQ0056E and RTQ0056C. These are nearly identical, with only the thermal pad being different in size…
Part Number: AMC7834 Hi experts,
My customer reports an issue with AMC7834: the local temperature reading is shifting dramatically. The ADC is configured as autonomous conversion mode. While other ADC input channels seems working properly. So I think the…
