Part Number: DAC7760 Hi,
I have a problem on some boards with DAC7760IRHA: it seems, that the interlally 4.6 supply is on, even though the pin DVDD-EN is tied with GND. The voltage on the pin DVDD is 4.3 V, if it is left unconnected.
Interestingly,…
Part Number: DAC7760 dear sir
We control the DAC7760 output voltage or current through the SPI interface, and then measure the voltage or current using a multimeter, directly connected to the connector.
In this process , we found short circuit between…
Part Number: DAC7760 Hi,
According to equation (1) in data sheet P28, even if the full scale code FFF0h is set during unipolar output with the 0-5V range setting,
it does not seem to be 5V in the calculation.
Should I correct it by setting 8010h in the…
Part Number: DAC7760 Other Parts Discussed in Thread: DAC8760 Hi,
Even when the soft reset bit is set to 1, is the current consumed by AIDD up to 3mA and DIDD up to 1mA?
Is there any other way to reduce the current consumption while the external power…
Part Number: DAC7760 Other Parts Discussed in Thread: DAC80501 , DAC60501 , DAC70501 , DAC8760 I've been having some trouble with overheating of the device and I need a design review.
In a past revision the alarm pin was tied to DVDD by mistake (someone…
Part Number: DAC7760 Hi,
If the HART-IN function is not used, can I leave the HART-IN terminal open? Or is it better to connect to analog GND via 22nF?
Best regards,
Part Number: DAC7760 Other Parts Discussed in Thread: MSP-FET , Hi,
We are thinking of mounting on the same board as the MSP430 microcomputer.
When writing software to the MSP430 from the MSP-FET tool, 3.3V is supplied from the tool side,
so 3.3V is also…
Part Number: DAC7760 Other Parts Discussed in Thread: TPS7A49 , TPS7A30 My intention is to use two DAC7760 on the same SPI line.
I saw the reference design which suggested me to use TPS7A49 for +VCC and -VEE for DAC, which I did.
I have gone through the…
Part Number: DAC7760 Hi Team,
I have some questions for BOOST, HART-IN & ISET-R pins.
-------
[Q1]
We don’t use BOOST pin.
Then, I guess that BOOST pin is OPEN.
Is my understanding correct?
If no, could you please let us know the proper way…
