Part Number: DAC161S997 We want to use DAC161S997 IC in the designing of Pressure transmitter. We are getting customer feedback that this IC has some difficulty in meeting the impedance requirement for HART at low frequency. They think it is design error…
Part Number: DAC161S997 Hi,
I had a customer wants to know on how much distance for the 4-20mA current loop transmitted for DAC161S997? Thanks.
Best Regards,
Ray Vincent
Part Number: DAC161S997 Other Parts Discussed in Thread: ISO7141CC Hi, We have developed our 4-20 mA loop current module that uses the DAC161S997 and it is working fine. We have been able to communicate using the HART protocol, however with a critical…

1.I want to know the response time of current Loop
I have confirmed in the data sheet that the settling time changes depending on the capacity.
I think the response time will change depending on capacity…
Part Number: DAC161S997 Hey team,
I had a customer who was wondering if an ESD route that went through the reference ground / DAC161S997 internal 40 ohm resistor would be acceptable or cause issues? They can route around the DAC via another node but were…
Part Number: DAC161S997 Hi,
I have a customer case that is looking to use the self powered approach for this device, but there is some confision about how all of the GNDs need to be connected. Can you provide guidance on if there are any specific rules…
Part Number: DAC161S997 Hi,
We are using DAC161S997RGHR in our 4-20mA converter application. We have designed the schematic as per datasheet but we are not getting current output. We have used 51 ohm resistor across DAC output to measure current. As per…
Christophe,
I haven't heard back from you for a while, so I wanted to check back with you on your loop setup. Have you been able to get the device to output the proper loop current? In my last post, I made a few debugging suggestions using measurements…
Part Number: DAC8740H Other Parts Discussed in Thread: MSP430F6736 , DAC161S997 I am developing pressure transmitter with DAC8740 and DAC161S997 with controller MSP430F6736. Some of engineers already working on it. Definitely they have written software…
Part Number: DAC161S997 Hello,
I have an issue with DAC161S997 circuit , when i tried to power up the circuit transistor Q1 is fully on and huge amount of current flowing the it
I have powered DAC with internal 3.3V regulator and 24V for loop supply from…
