MAX4121CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4121CPA is a high-speed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole double-throw (SPDT) channels housed in an 8-pin DIP package. The device operates with a supply voltage range of 3V to 12V and supports both single and dual supplies. Key electrical parameters include a typical on-resistance of 10 ohms, a bandwidth of 330MHz, and a channel-to-channel isolation of 70dB at 100MHz. The input signal range extends from VSS-0.1V to VDD+0.1V, allowing for true zero-signal switching capabilities.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides two independent SPDT analog switching channels within a compact integrated circuit.
• Supports bidirectional signal transmission with low on-resistance for minimal signal attenuation.
• Enables true zero-signal switching by accommodating input voltages beyond the power supply rails.
