Part Number: DAC8551 Tool/software: Hello，
The output voltage range of DAC8551 is 0-3.3V, and the external voltage reference voltage is 3.3V. The ADC output is connected to an operational amplifier, amplifying the output voltage from 0-5V. The DAC data…
Part Number: DAC8551 Tool/software: When Vdd=5V, Vref=2.5v, No issue.
When Vdd=5V, Vref=5v,Get output sine osillation, 1Vpp and 2.8-3.2Mhz oscillation.
When Vdd=5V, Vref=4.7v, Get output sine osillation, 1Vpp and 2.8-3.2Mhz oscillation.

Part Number: DAC8551 Other Parts Discussed in Thread: OPA227 , DAC80501 hi Sir
I Saw a TI reference design Which called SBAA345–January 2019, that spec is vout 0-5v, current 0-10A
now, i have a spec is vout 0-15v, iout- 1mA-300mA Adjust
did you have…
Part Number: DAC8551 Dear Sir/madam,
For DAC8551IADGKR part,
1. Can i connect VDD to 3.3V and Vref to 5V for 0 to 5V output? is this doable?
2. if I have two DAC8551 connected in parallel, can i use the Sync signal as chip select to choose which chip to…
Hi Andrew,
The DAC80501 is a newer device that we recommend to replace the DAC8551, and it has a SW reset. It does not have the same pinout so you would have to update that. It also does not expose the VFB pin of the output buffer. If that is a requirement…
Part Number: DAC8551 Is there a spice model available for the 2x amplifier (output buffer) inside the DAC8551. I would like to perform a load stability study as the application requires driving a capacitive load but at low speeds. Since the feedback is…
Part Number: DAC8551 I have some instances of DAC8551 that output is 2V instead of 5V.
VDD is 5Vdc, Vref is 5Vdc.
When I output 65535 with 24bit , it works fine at the beginning. After some use, some boards are giving me 2Vdc output instead of 5V.

Hi Experts,
We noticed a possible mistake in the DAC8551 datasheet.
Figure 46 shows 50kR feedback resistors on the opamp, which would create a gain of 2 at the output.
The other figures on the datasheet (as well as the text) do…
Part Number: DAC8551 Hi Experts,
I understand that the A-variant of DAC8551 has better accuracy than DAC8551IDGK.
Question between DAC8551IDGK & DAC8551IADGK: Given that we know the minor differences of both devices, are they interchangeable to the design…
Part Number: DAC8551-Q1 Hi Team,
Customer chose DAC8551-Q1, which needs to output a 5V 60Hz sine wave, but according to the description in the datasheet, it seems that it can only be a square wave.
