High-speed AD9708 AD9280 AD / DA Module FPGA Development Board Black Gold Description: Features: 1.Digital to analog converter (DA) circuit Such as hardware structure shown in the figure, the DA circuit is composed of a high speed DA chip, 7 Gai Butterworth low pass filter, amplitude Regulating circuit and a signal output interface. High speed DA chip we are using AD's AD9708. AD9708 is a 8 bit, 125MSPS DA conversion chip, built-in 1.2V reference voltage, a differential current output. The internal structure of the chip diagram as shown below: After the AD9708 chip differential output, in order to prevent noise interference, connected in the circuit of 7 Gai Ba Talwar Si low pass filter, the bandwidth of 40MHz, frequency response as shown below: The filter parameters as shown below: After the filters, we use 2 pieces of high performance 145MHz bandwidth operational amplifier AD8056, realize the difference Variational single ended, and amplitude adjustment and other functions, so that the whole circuit performance has been improved to the greatest extent. Range regulation, is using the 5K potentiometer, the range of output end is -5V~5V (10Vpp). Waveform display: 2.Analog-to-digital converter (AD) circuit As the hardware structure is shown in the picture, the AD circuit is composed of a high speed AD chip, attenuation circuit and a signal input interface Form. High speed AD chip we are using 8 developed by AD company, the maximum sampling rate of 32MSPS .AD9280 chip. The internal structure as shown below: According to the following configuration, we will AD input voltage range is set to: 0V~2V: Before the signal into the AD chip, we use a piece of AD8056 chip to construct the attenuation circuit, interface The input range is -5V~+5V (10Vpp). Attenuation after, input range to meet the input range of the AD chip (0~2V). The conversion formula is as follows: When the input signal Vin=5 (V) time, signal input to the Vad=2 AD (V); When the input signal Vin=-5 (V) time, signal input to the Vad=0 AD (V);kaPacakge Package Contents 100% Brand New 1 xHigh-speed AD9708 AD9280 AD / DA Module FPGA Development Board Black Gold 1 x cable We can also wholesale if you need a large quantity of item please contact us :) Shipping Info : We only accept your Paypal Address,Please Make sure it's 100% right.
