Part Number: DAC121C085 Other Parts Discussed in Thread: ISO1541 , Hi,
I am trying to get 0-10V analog output. I am using a DAC121C085 and ISO1541. Through a connector i am getting 24v and ground and with the same connector i am sending the analog value…
Part Number: DAC121C085 Hi all,
A customer uses the DAC121C085. in their application scenario, the machine power will sometimes frequently power down and power up. then in some case, the part will work wrong. So as stated in datasheet, the power on reset…
Part Number: DAC121C085 Hello,
I would like to use DAC12C085 with 2.5V full scale. Thus, we use 3.3V for Va and 2.5V for Vref.
However in the datasheet P.26 there is the description that "To use the full dynamic range of the DAC121C085, the supply pin…
Part Number: DAC121C085EVM Other Parts Discussed in Thread: DAC121C085 , Hi,
I would like you to confirm how we can get GUI and Firmware for DAC121C085 EVM.
According to user's guide, we need to request all of software for this EVM. However, it seems that…
I´m using the DAC 121C085 VSSOP 5V at Vref I write full-scale (FFFh) I have in the output 4.263V
If I writ (BFFh) I have 3.6V and I have 1.6V when I write (800h)
The VA pin is left float.
I'm sure the code is correct because when read back e reading…
Part Number: DAC121C085 Hi
There are rare I2C NACK from DAC121C085.
Customer have reported that if VA ramp up fast, it is ok, but there are NACK in case of slow Va ramp-up.
What is VA ramp up time? For example, VA 3.3V should be high in 1ms or 10ms.

Other Parts Discussed in Thread: DAC121C085 Hello,
the revised datasheet of the DAC121C085 (Revision E from January 2016) specifies two different I2C addresses for each possible address coding (table 1). Our observation is that only the first of these…
Part Number: DAC121C085
Hi Sirs, Would you pls advise the Rth(jc) and Pd(max) specifications of the DAC121C085CIMM thus we can calculate the max temperature in extreme load conditions? Can we refer to 240’C/W Rth(JA) and the 2.06mW Pd(max) from the datasheet…
Other Parts Discussed in Thread: DAC121C085 Hi,
I have been using DAC121C085, VSSOP-8pin package in my design.
Currently I have downloaded the latest rev of the datasheet - REVISED JANUARY 2016. Here are the difference in pinouts from the previous rev of…
Other Parts Discussed in Thread: DAC121C085 Hello, we have a problem interpreting your newest release of the DAC121C085 datasheet (Revision Januray 2016). There are inconsistencies in Table1 regarding the I2C Addresses the device responds to the different…
