Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: DAC8574 Tool/software: We use multiple DAC8574 on a bus as stated in the datasheet: "Address Support for up to Sixteen DAC8574s"
We use addresses lines on the chips A3, A2, A1 and A0
AA-AA 10 32 U10…
Part Number: DAC8574 Hello, Experts,
Here is the schematics to generate Analog signals through A and B chan.
Data could be sent on I2C correctly, Addr.0X4C, (0x98 was sent), control byte 0x10 and Data 0x5555, but no output either A and B.
Thanks.

The task is to generate output voltages between -2.048 and +2.048 V with a DAC8574. For this purpose the DAC is operated with +/- 2.5 V.
The I2C signals have a swing of 5 V referred to -2.5 V. The signal transmission with I2C works…
Part Number: DAC8574 Two DAC8574 are connected over i2c bus and controlled through ARM SBC. They show 0x48and 0x4c addresses by i2cdetect in linux. I have used 0011 and 0000 for them for (A3A2A1A0 )respectively for addressing. But while writing to DAC…
Part Number: DAC8574 Hello,
I have a question regarding the two Vdd pins on the device. I haven't been able to find any information on the two pins.
I would like to know if I can run the Vdd pin at +5.0VDC while running the IOVdd pin at +3.3VDC? Is…
Part Number: DAC8574 Hi,
1) What is the difference between DAC8574 4AT & DAC8574 69T written on the device?
2) I set 5V on four channels and saved this value in memory, when I turned off the device for few seconds and turned it on it shows 5V on four…
Part Number: DAC8574 Hi,
1) I want to known what is the storage temperature for DAC 8574 because it is confusing in the data sheet because negitive(-)is not mentioned.Screen shot is attached.
2) And DAC 8574 is not working properly when kept at -25 degree…
Part Number: DAC8574 Other Parts Discussed in Thread: LM4040 Dear Guys @ TI!
We made a simple circuit with your DAC8574 DAC. When I shunt the lower (U19) diode - so the VrefL goes to GND, the circuit works (almost) fine (on all 4 channels). In this case…
Part Number: DAC8574 Hello friends
I am using dac8574 for my project and I have a controller tm4c123, the controller and dac have been interfaced using i2c vref of the dac is 5v and Vdd is also 5v and IO Vdd is 3.3 and I am not using LDAC
Vrefl is grounded…
Part Number: DAC8574 Hello
We use DAC8574 to output 0~5V to control the air valve. VrefH=5V, VrefL=GND.
Does the current of Vout A~D all from VrefH?
If each Vout current =20mA, do we need VrefH input current=80mA?
Or we need add amplifier after Vout？ …
