Overview
The CD4052BPWRG3, produced by Texas Instruments, is a differential 4-channel analog multiplexer/demultiplexer. This device is part of the CD405xB series, which includes digitally-controlled analog switches with low ON impedance and very low OFF leakage current. The CD4052B is specifically designed for differential 4-channel multiplexing, allowing for the selection of one of four pairs of channels to be turned on and connected to the outputs.
The device operates over a wide range of digital and analog signal levels, from 3V to 20V, making it versatile for various applications. It features a single supply range of 3V to 20V and can handle analog signals up to 20 VP-P. The low quiescent power dissipation and high OFF resistance make it energy-efficient and suitable for applications where power consumption is a concern.
