SDP board(EVAL-SDP-CS1Z) is detected by both software and the led on SDP board blinks. But error AD5686R Evaluation Board(EVAL-AD5686RSDZ) was not detected appears after that.
Tired 2 software;
1. AD5684R Evaluation Software( CD came with EVAL-AD5686RSDZ…
The AD5686R has a very nice internal reference that I want to use as a reference throughout my board. This includes a SAR ADC which recommends a 1µF ceramic on its Ref input, to absorb the fast transients created during conversion. However, I don't know…
使用官方给的例程，电源和逻辑电源接3.3V，GAIN接地。RESEL接地。LDAC和RESET初始化时分别接低电平和高电平。
以下是主函数中的程序：
AD568X_SYNC= 0; //片选信号
AD568X_InternalVoltageReference(AD568X_INT_REF_OFF); //使用外部参考电压
AD568X_SYNC= 1;
delay_us(50);
AD568X_SYNC= 0;
AD568X_PowerMode(AD568X_ADDR_DAC_C,AD568X_PD_NORMAL…
Hello,
I have just implemented AD5685R in a new design however when powering up the system the AD5685R circuit (TSSOP16) get very hot.
If I strip of everything surrounding the circuit except for connecting 5V to Vdd and pin 10 (GAIN) and 0V to GND…
ColinL 's Questions was what I was also wondering about.. And your answer was Great.. Earlier I had seen the
AD5686 but concentrated on the AD5686R datasheet thinking that the chip without a Ref was probably an
older design model.... NOW I see…
Sorry for primitive questons.
I would like to use AD5686R by minimum control lines.
FPGA controls only 3 pins ,SYNCb,SCLK,SDIN.
Other lines will be fixed,LDACb = GND , RESETb = Vlogic, RSTSEL = GND, example.
Could I have any comment or attention about…
Hi folks,
I have a question regarding multichannel current sensing. First a description of the application: So far I have the AD5686R as a 16 bit, 4-channel precision voltage source (0-5V). At each channel of the voltage source I connect a 50kOhm resistor…
Hi Andrei,
This was from an older DAC design. The more recent ones like AD5686R/AD5685R/AD5684R (Rev. E) (analog.com) has the output amplifier gain independent from the reference source.

Q: How to configure multiple ADXXXX DACs in daisy chain mode?
A: A figure on the data sheet shows how to connect multiple devices in daisy chain mode. The SDO of the first device on the chain is connected to the SDI of the next device until the SDO of…
