Richard,
Sorry, I noticed in the datasheet that the SWIF is described as being able to operate in half-duplex mode. It also says that the DAC161P997, the acknowledge pulse constitutes the reverse data flowing from the device back to the controller. However…
Part Number: DAC161P997 Dears,
I use DAC161P997 to build 4-20mA. And I parallel one 47uF bulk capacitance to the loop receiver resistance. And there is a significant ripple measured as below. Vpp=200mV
Do you know about how to analyze the effects for…
Part Number: DAC161P997 Dear,
Please find attachment pdf 4-20mA loop. we found 10 out of 3 No. of dac breakdown after 1~2 day operation.
Can you give us assembly instruction for such IC ? Is there any chances if thermal pad or any other DAC 4-20mA loop…
Part Number: DAC161P997 Hello,
Following is our circuit diagram:
Iout is connected to a 330E resistor followed by the ground terminal of a bench top DC supply configured for 24V and current limit set to 40mA, while the positive of the DC supply is…
Part Number: DAC161P997 Other Parts Discussed in Thread: DAC161S997 , LM2936 Hello experts, I have a custom PCB designed based on the DAC161P997 evaluation board, currently the DAC doesn't respond to the bit stream I am sending. I can't see any ACK response…
Part Number: DAC161P997 Hi team,
The external BJT of DAC161P997 is BCX56-16 (JCET ) and the 20Ω resistance is 10ppm, 0.1%. After 4mA and 20mA verification at room temperature, and then test 4mA and 20mA at - 20 ℃, it is found that the 4mA maximum drift…
Part Number: DAC161P997 Hello,
We are building a 4-20mA transmitter using the DAC161P997. It is for industrial applications so an isolated design is preferred. We would like your advise about the following:
1) The mcu controlling the DAC is powered…

Part Number: DAC161P997 Other Parts Discussed in Thread: DAC161S997
I have a converter which converts 24V(loop+) to 5v and a LDO which converts 5V to 3.3V. Something happens without a reason like letting output pin of DAC(loop-) float or connecting it…
