Analog switches and multiplexers route analog and digital signals in test equipment, data acquisition front-ends, audio routing, and signal conditioning circuits — providing low on-resistance, high off-isolation, and wide signal bandwidth. Our analog switch inventory covers single/dual/triple/quad SPST, SPDT, SP3T to SP8T configurations, analog muxes/demuxes, and hot-swappable signal path switches from Texas Instruments (TMUX/SN74 series), Analog Devices (ADG series), Vishay (Si series), Microchip (MCP401x), and NXP — with on-resistance from 0.5 Ohm to 200 Ohm, bandwidths from DC to 1 GHz, and supply voltages from 1.8V to 16V.
Popular analog multiplexer ICs such as CD4051, CD4052, CD4053, DG408, and MAX383 remain among the most widely used chips in industrial test equipment and data logging systems — but face periodic supply constraints. Welllinkchips stocks these classic multiplexer ICs in DIP and SMD packages alongside hard-to-find high-performance analog switches for RF and high-voltage applications.
