Low-Voltage, CMOS Analog Multiplexers/Switches

Description

Create a design and simulate using EE-Sim^® tools:

The MAX4051/MAX4052/MAX4053 and MAX4051A/MAX4052A/MAX4053A are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4051/A), two 4-channel multiplexers (MAX4052/A), and three single-pole/double-throw (SPDT) switches (MAX4053/A). The A-suffix parts are fully characterized for on-resistance match, on-resistance flatness, and low leakage.

These CMOS devices can operate continuously with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0.1nA at +25°C or 5nA at +85°C (MAX4051A/MAX4052A/MAX4053A).

All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±5V or a single +5V supply.
