Part Number: DAC70501 Hello Teams
Why the recommended AW pattern in the Datasheet, does describe the PD resister is between SPI2C and GND? Even if this PD resister is not implemented, it seems that the circuit can be established and SPI communication…
Part Number: DAC70501 Hello,
We have an old audio board product which made use of an LTC1658 DAC. Our audio board consists of a microcontroller, flash and the DAC. Recently, the LTC1658 DAC became obsolete. We chose to replace it with the DAC70501MDQFR…
Part Number: DAC70501 We've got the picture of power supply voltage waves during POWER termination. I have question about voltage behavior and relationship between VDD and VREF.
Part Number: DAC70501 I'd like to know about Power-On-Reset described on page 22.
The data sheet says that " To make sure that a POR occurs, VDD must be less than 0.7 V for at least 1 ms."
Is there anything else I need to do to meet this requirement…
Part Number: DAC70501 How long does it take for the VREIO pin to output 2.5V after the device is powered on (VDD = 2.7V)?
Also, how long does it take for the 2.5V output of the VREFIO pin to turn off after rewriting the CONFIG REGISTER to disable the…
Part Number: DAC70501 When the reference input voltage is 5V and VDD is also 5V, Do I have to set the REF-DIV to 1(the reference voltage is internally divided by a factor of 2) and also set the BUFF-GAIN to 1(the buffer amplifier for corresponding DAC…
Part Number: DAC70501 Hi Team,
Currently, I used VDD=3.3V and set BUFF-GAIN=1, REF-DIV=0.
The configuration will trigger a reference alarm condition, we do see all the DAC outputs go to 0 V
Can we see normal Vout if VDD is changed to 5V and BUFF…
Part Number: DAC70501 I would like to know about the frequency response characteristics. If SCLK is set to 12MHz and the voltage is output as a sine wave up to full scale (LSB to MSB), how much band can be output? The communication mode is SPI.
I want…
Part Number: DAC70501 I'd like to know how to send a command via SPI mode.
For example, what command should I send via SPI mode if I want to make the following settings?
Set the reference voltage to the external input.
Outputs mid scale voltage…
