Product Description

Original chip DAC90x, parallel communication. Output rate of 165MSPS, compatible with 5V and 3.3V level. Output voltage plus or minus 5V. Support 10-14 bit accuracy, internal reference voltage. Including the following chip: DAC900, 10 bit accuracy, DAC902, 12 bit accuracy; DAC904, 14 bit accuracy.





The 1 module is the default 5V power supply, communication level is also 5V, in the first road (labeled 7) output positive and negative 5V signal. When using STM32 or FPGA 3.3V level communication, can be adjusted to 3.3V position, or the label 11 direct power 3.3V or 5V.
2 positive and negative 12V power supply, when the power supply for the second circuit, so that the output of positive and negative 10V signal. Do not use the second way, no power supply.
3 positive and negative 12V input voltage protection. To prevent the high voltage burn chip.
Second 4 channel amplifier filter circuit can be adjusted by adjusting the R15, R14 to adjust the magnification, the circuit diagram.
Second 5 way signal output. The output is only when the label is supplied with an additional positive and negative 12V at 2.
6 negative voltage regulation circuit of the first circuit amplifier circuit.
7 first signal output. Default output positive and negative 4.1V sinusoidal signal.
8 first circuit.
9 first level signal conditioning circuit, including current voltage and RC filter
10 DAC904 chip
11 3.3V or 5V power supply or output. When using the label 1 power supply, the voltage output can be used here. When power supply is not used, it can be used for power input.
12 data bus.
The output of the module is: the first +-4.1V second way: +-10V (need additional power supply), the second way is the first way to enlarge!
