Module description



AD9220 is a new generation of high-performance, 12-bit analog-to-digital converter, powered by a single power supply. It has true 12-bit linearity and temperature drift performance, and 11.5-bit or better AC performance. The AD9220 uses a high-speed, low-cost single CMOS process and a novel architecture. The resolution and speed both reach the level of the existing hybrid single-chip solution, but the power consumption and cost are much lower. Built-in on-chip high-performance, low-noise sample-and-hold amplifier, select external reference voltage to meet the application's DC accuracy and temperature drift requirements. The device uses a multi-stage differential pipeline architecture; built-in digital output error correction logic; can provide 12-bit accuracy at the rated data rate, and ensure no missing codes in the entire operating temperature range. It is suitable for IF down-conversion communication system.


Precautions for using the module
(1) The module is a low power consumption module, the power supply does not exceed 6V, and the signal input voltage cannot exceed 5.5V.
(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.
(3) The output signal line is recommended to be as short as possible. The module interface is SMA. It is recommended to use the coaxial cable SMA interface wire. Poor contact or poor quality wires may cause signal attenuation or excessive noise.
(4) The delivered code is only used for the supporting main control board. No single-chip microcomputer tutorial is provided. Functions other than product details display need to be developed by yourself.
(5) If you need to simply test the function of the module, it is recommended to use it with the control board of our store; after the correct wiring, the power supply to the control board can realize the signal acquisition display.
Frequently asked questions
Q: How much sampling rate can the AD9220 cooperate with our main control board?
A: Because the main frequency and IO speed of the microcontroller are not enough, we did not do the highest speed test of the main control board. If we need to reach the sampling rate of 10MSPS, we generally need high-speed logic devices such as FPGA.
Q: I want to use the 12-bit resolution of AD9220 for 1-3V acquisition, what do I need to do?
A: According to the schematic diagram, the voltage range collected by the AD9220 is Vin = Vb ± Ref; that is, it is necessary to set Vb = 2V and Vref = 1V.
Q: Why is the data I collected with the STC51 microcontroller wrong and there is a large jump, what is the reason?
A: Generally speaking, there are two possibilities, one is that the signal itself is relatively jittery, and the other is that the communication level is incompatible. The AD9220 is a 3.3V communication level. If you use 5V-TTL, it will interfere with the module.
Q: Use AD9220 and the matching main control board; AD9220 uses 5V power supply, can't collect 5V voltage?
A: First of all, the power supply between the AD9220 and the main control board needs to be in common ground, otherwise the AD9220 cannot receive and return normal signals, so it cannot be collected. Secondly, the AD9220 has reverse connection protection of the power supply; it is recommended to collect 5V voltage to supply power of about 5.3V; but can not exceed 5.8V; so that you can collect 5V
