Electrical energy collection device

The utility model provides an electrical energy collection device which comprises a collection circuit used for collecting an electrical signal and a 16-bit analog-to-digital converter (ADC) which is connected with the collection circuit, is used for carrying out analog-to-digital conversion of the electrical signal and comprises eight paths of track and hold amplifiers. Through the electrical energy collection device provided by the utility model, the effect of collecting eight paths of analog signals at the same time can be achieved with just one piece of 16-bit ADC, the 16-bit ADC comprises eight paths of track and hold amplifiers whose functions are equivalent to a following circuit, so the driving can be raised in the condition of not adding the following circuit, the number of components in the device is reduced, and the circuit structure is simplified.
