Title： AD7606 Multi-Channel AD Data Acquisition Module 16-bit ADC 8-Channel Synchronous Sampling Frequency 200KHz Module model: Analog-to-digital conversion module (AD7606) Module power supply: DC5V Module current: 20mA (MAX) Module communication protocol: SPI serial, 8-channel data parallel Module provides routines: STM32F103RBT6 Example platform: STM32F103X-M3 Module control: Signal level: 3.3V Module input voltage range: 5V or ±10V (software switching range) Input impedance: 1M ohm ADC resolution bits: 16 bits Sampling rate: 200KSPS (all channels) Number of input channels: 8 channels independent (synchronous sampling) Module input interface: 3.81-8PIN terminal Reference voltage: internal 2.5V (weldable SOT-23 package external input reference) Oversampling modes: 6 (2 times, 4 times, 8 times, 16 times, 32 times, 64 times) Module interface type: 3.81-10PIN socket, XH2.54 double row pin data interface Module size: 50x50x12mm Module weight: 23g Frequently Asked Questions: 1. (Q): What is the sampling rate of AD7606 serial data?(A): Theoretically, it can achieve 8-channel 200K serial data output, but the general method of using serial data for single-chip microcomputers cannot reach 200KSPS, because the main frequency and IO speed of the single-chip microcomputer are not enough.2.(Q): Will there be a problem if the pins CA and CB on the back of the quilt are short-circuited together?(A): According to the schematic diagram, CA and CB are connected through jump points, which is normal.3.(Q): After the module is driven normally, the pins that are not connected to voltage also display voltage, is it normal?(A): The module is collected by 8-channel colleagues by default, and the floating voltage on the pin will also be collected when there is no voltage connected. The pin can be directly grounded and sent to 0 voltage.4. (Q): Is the maximum value 65536? How is this data converted?(A): The highest bit of AD7606 is the sign bit. When the range is ±5V, 0~32767 corresponds to 0V~5V, 32768~65535 corresponds to -5V~0V, 32768~65535 is a 16-bit unsigned integer number, which is actually equal to 16 bits Signed numbers -32767~0, the same reason, plus or minus 10V is also converted in this way.
