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…
Hi Harish,
I think I misunderstood your question originally. I think you are getting nearly the correct value for the output range, but you are trying to understand the errors in output?
When you power cycle the device the output should be at zero…
Other Parts Discussed in Thread: DAC8574 , MSP430G2553 I recently got the MSP430g2553 launchpad to experiment with the I2C interface. I am trying to program the DAC8574 which has I2C interface. I have downloaded the sample library from TI on using USCI…
Other Parts Discussed in Thread: DAC8574 Hi,
I'm trying to connect eZdsp F28335 with DAC8574. This is done by MATLAB Simulink. My problem is: when i use the default slave address register ( 80 ) on i2c lines everything is perfect (I use logic analyzer…
Hi Austin,
Welcome to the E2E forums!
Unfortunately we do not have any I2C compatible devices 16-bit devices with an octal channel. We do have a quad channel option on 16-bit resolution (DAC8574), but it is definitely not drop in compatible.

Hello Huck,
After performing some experiments with a DAC from the same family line, DAC8574, I've verified that the read accesses the DAC Channel register, which directly corresponds to the DAC output voltage. I've tried all configurations of L1, and…
Other Parts Discussed in Thread: DAC8574 Hi,
I have some problems to comunicate with my digital pot in I2C (Microchip MCP4552).
I work with a custom board, I can already comunicate with an I2C FRAM (FM24V10-G) and an I2C DAC (TI DAC8574)
First what…
Hi Tom,
I have the same Problem with DAC8574.
We use 5 of them on one I2C bus.
Readback from 3 of them works fine, but two sharing the same I2C address respond both to the readback command even they have different A2 addresses.
Could you please…
Other Parts Discussed in Thread: DAC8574 All,
I've read the Clock Generation section of SPRU175A. I'm trying to communicate to a DAC8574 from a C6713 (master), and I'm confused as to how to specify the I2C prescalar register (I2CPSC) when it is not…
