DAC1220 digital analog conversion data acquisition module 20 bit DAC16 bit adjustable positive and negative 10V voltage referencModule introduction
DAC1220 is a low power serial digital to analog converter that can realize 20 bit or 16 bit linear conversion within a certain temperature range. In principle, Σ - △ technology is used to realize its linear characteristics, which can be configured into 16 bit input mode and 20 bit input mode by software. The setup time can reach 0.003% within 15ms for 20 bit input and 0.012% within 2ms for 16 bit input. The maximum output voltage is twice of the external reference voltage. The on-chip self calibration circuit can dynamically reduce the offset and gain errors, and the maximum output linear error is only ± 0.0015%. The DAC1220 adopts synchronous serial interface. A single conversion system only needs two signal lines to control, and a multi conversion system needs chip selection signal to cooperate. The single power supply (+3V or+5V, cM0s) structure is adopted to ensure its low power consumption characteristics. It has the characteristics of low noise, small linear error, small temperature drift, etc. The DAC1220 can be used for industrial control or high-precision detection and measurement systems.

Precautions for module use
(1) The module power supply shall not exceed 5.5V.
(2) Since the module is a high-precision device, it is recommended to use linear power supply to avoid unnecessary interference.
(3) It is recommended to use SMA corresponding interface for output signal line. The interface mismatch may easily lead to poor contact, and poor quality wire may lead to signal attenuation or excessive noise.
(4) The code delivered is only for the use of the supporting main control board, and does not provide code explanation. Functions other than baby details display need to be self-developed.
(5) If you need to simply test the function of the module, it is recommended to use it with the control board of our shop. After correct wiring, you can supply power to the control board to achieve analog voltage output.

FAQ
Q: What is the output voltage of the module? What is the driving capacity of the output voltage?
A: At present, the circuit of the module can output ± 10V, and the driving capacity is within 10mA.
Q: Use a voltmeter to test whether the voltage is normal. What is the voltage drop after connecting the load
A: Since the module has only 10mA drive capacity, when the load is too small, the output voltage will be pulled down
