Part Number: DAC7571
Hi,
This is my block diagram and has one issue.
When VDD2 is 3.3V, I2C operation is normal .
But, when VDD2 is 0V, SCL & SDA level of DAC7571 go down around 2.2V and I2C operation is abnormal.
As I know, I2C is BUS. So, SCL &…
Part Number: DAC7571 Other Parts Discussed in Thread: DAC8760 Because of cost constraints, I want to use the DAC7571 to output four independent voltage signals, and control the voltage-current conversion circuit to output four 4-20mA. Is there a voltage…
Part Number: DAC7571 We have to re-calirate an Sensoramplifier once a day, therefore we want to use the DAC7571 to create an analog "referenz" signal . Test-Spezification: -> 12-Bit DAC7571 at exact 3,0000V and 25,00°C, -> always use…
Part Number: DAC7571 Other Parts Discussed in Thread: DAC60501 is there any part having same spec, performance, pin to pin with DAC7571, but operation from -40℃ to 125℃ ？or any recommendation ? thank you.
Part Number: DAC7571 Hi Sirs,
Sorry to bother you.
1. VDD is 5V_STBY, and I2C signal pull up to 3V3 Run, as shown in the figure, please help to confirm whether this behavior is correct? Or I2C also pull up to 3V3_STBY is more suitable?
2. As shown schematics…
Part Number: DAC7571 Hi Sirs, Would you pls advise the INL and PSRR specifications of the DAC7571 which is not listed in the datasheet? Thank you and Best regards, Wayne Chen 09/20/2018
Part Number: DAC7571 Other Parts Discussed in Thread: CC2650 Tool/software: Code Composer Studio Hello everyone! It's my first try using I2C and I need to configure a DAC7571 to get in output a sine wave with 1V peak amplitude and 30Hz frequency on a cc2650…
Part Number: DAC7571 Other Parts Discussed in Thread: ADS1113 Hi team,
My customer use two I2C devices, DAC7571(0x4d), ads1113(0x48),
at first, the DAC7571 set voltage 4.5v, then we write ADS1113 make the DAC7571 output to be 0.8v, we check it and find…
Part Number: DAC7571 Tool/software: TI-RTOS Hi Sir
I have two questions about DAC7571 design as below.
1. We use CPU I2C to control DAC7571 and has stable DC output level.
Q1. If we only disable CPU and DAC7571 still have power supply, Does output level…
Part Number: DAC7571 Other Parts Discussed in Thread: ADS1113 Hi team,
we use DAC7571 and ADS1113 at the same i2c line, DAC7571 setting voltage is 4.5v, when write ADS1113，the address is 10010000 DAC7571 broadcast address. Then the DAC7571 output become…
