Description

Technical Field

[0001] The utility model belongs to the technical field of chips, and in particular relates to a device for connecting an analog signal to an A2B bus. Background Art

[0002] The existing A2B bus solution is divided into one master node and four slave nodes. The master node uses an AD2428WCCSZ chip to transmit A2B bus data. Each of the four slave nodes uses an AD2427WCCSZ chip to transmit A2B bus data.

[0003] In the existing technology, each slave node uses an AD2427WCCSZ chip, and the entire architecture solution requires a total of four AD2427WCCSZ chips. Since one AD2427WCCSZ chip is expensive, the cost of the entire architecture solution is high. Moreover, the AD2427WCCSZ chip is currently in short supply and the production capacity cannot meet the demand. Utility Model Content

[0004] The purpose of the utility model is to provide a device for connecting an analog signal to an A2B bus, so as to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a device for connecting an analog signal to an A2B bus, comprising:

[0006] master node;

[0007] A slave node, connected to the master node;

[0008] Four analog signal microphones are all connected to the slave node.

[0009] Preferably, the master node is configured as an AD2428WCCSZ chip for transmitting A2B bus data.

[0010] Preferably, in any of the above solutions, the slave node is configured as a repeater, which includes an AD2427WCCSZ chip and two ES7201 chips.

[0011] Preferably, in any of the above solutions, the slave node is configured as a repeater, which includes one AD2427WCCSZ chip and two ES7243Q chips.

[0012] The technical effects and advantages of the utility model are as follows: the device for connecting analog signals to the A2B bus adopts a master node, a slave node and four analog signal microphones. The slave node is a repeater, which has an AD2427WCCSZ chip and two ES7201 chips, saving three AD2427WCCSZ chips, reducing the overall solution cost, and alleviating the problem of insufficient production capacity of the AD2427WCCSZ chip.
