The utility model discloses a multi-turn encoder circuit, which comprises an encoder chip, and a magnetic ring is arranged right above the encoder chip. The angle sensor is arranged on the encoder chip and is used for acquiring current single-circle position data and a corresponding absolute value angle; the turn number sensor is arranged on the encoder chip and is used for storing turn number data; the EEPROM device is connected with the encoder chip and is used for storing position compensation data of the encoder chip in calibration; the position acquisition module is connected with the encoder chip and is used for reading the absolute value angle and turn number data of the encoder chip to obtain joint position information; according to the multi-turn encoder, the multi-turn position of load output is recorded, meanwhile, by improving the circuit structure of the multi-turn encoder, accurate recording and obtaining of robot joint position information can be achieved, and the stability and reliability of t
