Hello Stephan,
ADALM1000 uses 16bit converters ( AD5663R for digital to analog conversion and AD7682 for analog to digital conversion) and offers voltage and current operation from 0 to 5 Volts (V), from -200 to 200 milliamps (mA).
问题:AD5663R无缘无故的没有电压输出了
出现频率:有时几天1次,有时几个月一次,有时1天几次
PCB结构:一个大板上插了8个一模一样的小板,电源是从大板供到小板。
AD5663R就是在小板上,小板上还有 ATmega16L、AD7705等;
小板上有信号接口与示波器连接。
在8个板上都出现过AD5663R无电压输出(不是8个板同时出现状况,没有规律可寻)
已经实施过的检查:
①掉电引起的复位-----因为PCB上还有MCU,AD7705等都不会出现复位,所以排除了电源掉电…
the input clk period = sclk =40Mhz
the timing set as the pic upside, and I set the input data rate synchronized with the DAC output as 40M/253clk=158.1Khz,
the verilog code is as below
//clk_in == 40Mhz module AD5663R( input clk_in, input [15:0…
1. I don't know the exact reset voltage for the AD5663R. Based on similar DACs it usually happens between 2V and 2.5V.
2. The power on reset is primarily used when powering from 0V. There will be some hysteresis in the circuit so if the power suppy…
There are many mismatches in noise characteristics found in datasheets of nanodac and nanodac+ families.
Let's examine AD5689R one first.
DAC output NSD (DAC code = midscale, 10 kHz; gain = 2) is 300 nV/√Hz and LF noise 6 µV p-p. With gain 2 and…

nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.
nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…
It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.
In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…
The AD5664R has two on-chip reference options available, 1.25V and 2.5V. What is the recommended supply voltage in each case?
