Part Number: DAC7718 Hi,
There is wrong offset and abnormal output in power-on/off as below description.
1. OFFSET_A is around 2.6V at 000h with dual supply. When it's 800h, OFFSET_A was 0V.
2. Output is around -5V with RSTSEL->IOVDD, /USB/BTC ->…
Part Number: DAC7718 Team,
we observe the DAC7718 heating up to 45 degrees C when the negative -5V voltage is applied to AVss (through a 1kOhm resistor). The AVss is taking 2.5mA, its voltage is -2.5V.
When Avss is grounded, the device is not heating up…

Part Number: DAC7718 Team,
we've observed oscillations on the reference input of the DAC (in amplitude, around 100mV, few tens of kHz). Removing the 1uF capacitor in the Vref, the oscillations were gone.
Afterwards we've observed similar oscillations…
Part Number: DAC7718 In the datasheet it lists:
Power-supply rejection is 0.05 LSB with a condition of AVDD = +33V to +36V.
Can you explain what that specification/condition means?
Part Number: DAC7718 Other Parts Discussed in Thread: DAC7716 Dear Team,
On the datasheet of DAC7718, AIDD is given as 7mA(max) in “ELECTRICAL CHARACTERISTICS: Single-Supply (continued)” section. However, Figure 84 max source current looks like to be…
Part Number: DAC7718 Hello E2E,
Please let me know how to calculate for output impedance of DAC7718. I found it that 0.5-Ω when code = 0x from datasheet. I want to know output impedance when from 0x000h to 0xFFFh.
Best regards, ACGUY
Part Number: DAC7718 Dear Specialists,
My customer is considering DAC7718 for Analog Voltage Output and has questions.
Could you please advise?

(1) I'd like to know the architecture of output stage in more detail. The datasheet is not enough. …
Part Number: DAC7718 Other Parts Discussed in Thread: LM3880 Hello,
I'm having trouble to communicate with my DAC7718. It might be totally unrelated to my question, but I just wanted to check this out before moving further.
I've been reading about…
Other Parts Discussed in Thread: DAC7718 Hi
We have a question about DAC7718.
Can you calculate a spent time from the time starting control with SPI to the time its to be reflected as an output? We want to know what kind of elements should be considered…
