GXSC 16 bit synchronous sampling analog-to-digital converter replaces AD7665 for GPRS remote vibration detection

With the rapid development of computer technology, vibration data acquisition now mainly uses microcomputers for digital testing and analysis. Vibration testing instruments are mainly intelligent instruments with microcomputers as the core. The first step of digital testing is to convert the analog data measured by sensors from the tested equipment into digital data. Therefore, the accuracy and speed of analog-to-digital conversion will directly determine the accuracy and speed of digital testing and analysis.

The 16 bit synchronous sampling fast, low-power successive approximation analog-to-digital converter of GXSC can replace AD7665 for data acquisition of GPRS remote vibration. The chip has a data throughput rate of up to 570kSPS and is equipped with low sound and wide bandwidth sample and hold amplifiers, improving the flexibility of the peripheral circuit design for AD conversion in the acquisition system.

The GXSC analog-to-digital converter utilizes signals and internal oscillators to control the conversion process and data acquisition of the chip. It has a high-speed parallel interface and a high-speed serial interface, creating conditions for the interface connection between the device and the microprocessor or DSP. The chip only uses a 5V power supply to support the conversion of ± 10V and ± 5V true bipolar input signals. The product advantages are as follows:
