Part Number: DAC7578 Tool/software: Hi TI expert:
I get a problem in my design when I try to use MCU I2C communicate with DAC7578SPWR.
The following pictures are the waveforms get from the pins of DAC7578SPWR:
As the picture shows, the master I2C data…
Part Number: DAC7578 Tool/software: Hi, We have a design with multiple octal DACs DAC7578SRGET on the same I2C bus. The LDAC hardware pins are tied together and driven from a GPIO from the MCU. We are able to succesfully write to individual DAC channels…
Part Number: DAC7578 Tool/software: Hi team,
Customer is evaluating DAC7578SRGER in their project, however there is no footprint info in datasheet, could you help share latest datasheet with package info inside it?
Thanks and Best regards
Will
Part Number: DAC7578 Tool/software: Hi Team,
I had a question regarding the DAC7578. Can the output of the DAC be switched at higher frequencies (10kHz)?
Looking at the datasheet, the highest update rate is 188.88 kSPS so it should be able to output frequencies…
Part Number: DAC7578 I have an application with 5 octal DACs p/n DAC7578 devices on a shared I2C bus operating at 400 kbps. Each device has a unique address, obviously. I tried writing 0x90 followed by a command/access byte of 0x00, then 2-bytes of left…
Hi Sathya,
Yes, IOUT in equation 4 from the snip you share represents the current output from the DAC, which is the margining current in your case.
If your margining current is ±5μA then you should choose the smallest possible IOUT range which…
Part Number: DAC7578 Hi team,
For the DAC7578 does the VDD marked below need to be same as the DAC supply voltage. In my customer's case the VDD marked below (pull up for I2C resistors ) is 3.3V and the DAC operates at 5.5V.
Will there be a communication…
Part Number: DAC7578 I am trying to calculate the output Voltage range for input voltage range of 0 to 3.3V using DAC 7578 where Vref =3.3V and AVdd = 3.3V. Is their any formula that I can use to calculate the range? or can I use Analog engineer's calculator…
Part Number: DAC7578 Hello,
I am having problems generating an output voltage.
My steps are like this:
1. Speak to the slave (DAC): 0x4A --> It gets acknowledged
2. Write to DAC input register channel A, and update DAC register channel A: 0x30 as Command…
Part Number: DAC7578 I'm using this DAC to bias the front-end channels of a custom ASIC. We've been seeing some issues with oscillations and bandwidth limiting (lower than expected) and through testing we believe that that the DAC's output stage might…
