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: DAC6578 Good afternoon,
Overall question: Do I need to map pins 1 or 8 to anything? Do i need to provide the DAC with any other commands to possibly shift its input from the data buffer to the register? Do I need to further power on the DACs…

We have shorted the DAC6578 pin 3 (AVDD…
Hi INABA-san,
Sorry for the delayed response. The digital logic is connected to the AVDD supply. the VREF is used for the analog section only. I am not able to guess why the floating level would have a relationship with the VREF. It should be always related…
Part Number: INA237 Other Parts Discussed in Thread: DAC6578 We have a board in which we use 15 INA237 devices on a single I2C bus addresses 0x40-0x47, 0x49-0x4F
In addition, we have DAC6578 at address 0x48 on the same bus
Device at address 0x47 does…
Part Number: DAC6578 Other Parts Discussed in Thread: DAC7568 Hello,
We use DAC6578 and ADDR1=Float, ADDR0=0. Slave address should be 1001100 but Ack respond when address 1001010. From this, ADDR1 seems changed from Float to 1. We see this issue in low…
Part Number: DAC6578 Hello, I have two questions about DAC6578.
With a product using DAC6578SPW, I do CPU and I2C bus connection. I connect other slave devices (example EEPROM) to the same bus, too.
With other devices, the following methods are recommended…
The spec of 6578's capacitive load stability is 470pF@RL= infinite and 1000pF@RL=2kohm. I understand this spec is upper limit. Is it right? If CL is 4.7uF and RL is 5.6k, how to keep stability? There isn't a series resistor before 4.7uF.
Other Parts Discussed in Thread: AMC7812 , DAC6578 AMC7812's I2C is 3-wire series interface, but DAC6578's is 2-wire one. Are they connected in the same I2C bus? If yes, how to do?
