Part Number: DAC1220 Hello!
The datasheet is a little ambiguous about exactly what's going on at the Xin and Xout pins. It is stated that a 2.5 MHz crystal is recommended for best performance. If nothing is connected, does it have it's own internal…
Part Number: DAC1220
Dear TI Technical Support Team,
I design a mini board that only has DAC1220 IC on it. The board is two layer (Bottom is solid GND plane), crystal is 2.5MHz (ECS-25-S-1X ,12pF load cap), , voltage reference is 2.5V (MCP1501)…
Part Number: DAC1220 Hi team,
My customer is using DAC1220 for analog output, and they have tested 5 samples, all of them output 2.56V at power up, which is not desired. I've recommend to write register CALPIN to disconnect output during calibration…
Part Number: DAC1220 Hi Experts,
Good day.
We would like to ask about the oscillator involved when designing DAC1220 device.
When designing the DAC with 5V for both analog/digital supplies: if an external OSC is used to feed at Xin, do we have to…
Hi Paul,
I am sorry for late reply. I was not at the laboratory.
I tried both version. The microcontroller (teensy board) is DIP package. I mounted teensy on breadboard and used wires to make interface with DAC1220 (it was on different pcb). The out…
Part Number: DAC1220 Other Parts Discussed in Thread: USB2ANY Hello Experts,
I want to control DAC1220 through the computer using SPI.
USB type-A pinout >> Vcc, D+, D-, GND
DAC1220 SPI pinout >> SCLK, SDIO
How should I /is it possible to interface…
Part Number: DAC1220 Other Parts Discussed in Thread: DAC8831EVM , DAC8831 Hi Experts, May I ask for help? I would just like to confirm at the datasheet from the DAC1220 at page 5. Output noise voltage vs Frequency. What frequency is meant here? Is this…
Part Number: DAC1220 Hi Team,
Do you have thermal information for this device DAC1220E ?
I can not find it in datasheet.
Theta JC top
Theta JC bottom
customer needs the thermal resistance from the junction to the top of the case and to…
Part Number: DAC1220 Hi,
This is my first time to use DAC1220 EVM board to connect our own microcontroller through SPI interface, and I have some question for the startup sequences. I used the half-duplex SPI(mode 1,clk idle=0, the second edge to capture…
Part Number: DAC1220 Hello,
i can't find out decision, that's why i have to ask.
Our problem: DAC1220 unstable working.
What we have:
Fxin=2.5Mhz
Fspi_clk=200kHz
20bit mode, C1=10nF, C2=3.3nF.
DVdd=5Vdc, AVdd=5Vdc, they were created with…
