DAC1220 Digital-to-analog Conversion Data Acquisition Module 5V 120mA 20/16 Bit Adjustable

Description:
- 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, using Σ-△ technology to realizes its linear characteristics, which can be configured into 16-bit input mode and 20-bit input mode by software. For 20-bit input, the setup time can reach 0.003 within 15ms. For 16-bit input, the setup time can reach 0.012% within 2ms at most. The maximum output voltage is twice the external reference voltage. The on-chip self-calibration circuit can dynamically reduce the offset and gain error. The maximum output linear error is only ± 0.0015%. The DAC1220 uses synchronous serial interface. A single conversion system can be controlled by only two signal lines. Multiple conversion systems need chip selected signals to cooperate. Single power supply (+3V or +5V, cM0s structure ensure its low power consumption characteristics, low noise, small linear error, small temperature drift, etc.) makes DAC1220 can be used for industrial control or high-precision detection and measurement systems.

Note:
- The module power supply does not exceed 5.5V.
- Since the module is a high-precision device, it is recommended to use linear power supply to avoid unnecessary interference.
- It is recommended to use SMA corresponding interface for output signal line. Mismatched interfaces are easy to cause contact.
- Poor and inferior wire may cause signal attenuation or excessive noise. 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.
- 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.
