Part Number: DAC8552 Other Parts Discussed in Thread: DAC8550 , DAC8551 ,
For the DAC8550 and DAC8551 the data sheets have been revised in 2017 (some data about linearity and ESD have been updated or added), but the DAC8552 is still from 2006.
Is there…
Other Parts Discussed in Thread: DAC8501 , DAC8551 Anyone know the difference between these two DACs other than price (8551 is cheaper)? We use the DAC8501 to generate audio with the ref fixed at 1.1 V and do not use the multiplying capability. Low power…
Other Parts Discussed in Thread: DAC8551 , OPA703 , OPA277 Hello, all
Now we have one inquiry regarding bipolar output configuration of DAC8551 from our customer.
Please refer to the item below, and feedback us with your comment.

Hi Varun,
Below is TI's application note with DAC8551 that is interfaced with XTR116 in 2-wire V-to-I 4-20mA current loop. Note that marked orange nodes are referenced to Io or pin4 in XTR116 IC. These ground references are "floating" with respect to…
Other Parts Discussed in Thread: DAC8551 1. Can I use 5V for Vdd and 2.5v for Vref?
2. Can I connect a resistor between Vfb and Vout and increase the gain for the output stage. I added 20K ohm resistor between Vfb and Vout and noticed the voltage stabilize…
Part Number: XTR115 Other Parts Discussed in Thread: XTR117 , XTR116 , DAC8551 , XTR111 Hi,
We are facing issues in the XTR115 chip (4-20mA Transmitter) during the EMI/EMC Conducted Sustainability (CS) Test of our product.
The issue is that 4-20mA current output…
Siavash,
A possible way is to use a low power DAC such as the DAC8551, and low-power digital isolation between the controller and DAC.
For example, you could use the DAC8551+XTR116 circuit presented on this 2-wire 4-20mA Transmitter, EMC/EMI Tested Reference…
Hi Fularam,
You have two 4-20mA V-to-I design options.
XTR116 / XTR117 parts are 2-wire 4-20mA transmitters, see the 4-20mA current loop in blue and red twisted pair wires below.
You will need two of DAC8551s and implement the following loop powered 2-wire…
Part Number: DAC8554 Other Parts Discussed in Thread: DAC8551 Hi everybody, I have a board with DAC8554 and I am using SPI interface of Labview FPGA to communicate with the board. LDAC input of DAC8554 is grounded, ENABLE and SYNCH are connected to CS…
