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.
