Low-Voltage 8:1 Mux/Dual 4:1 Mux/Triple SPDT/Quad SPDT in UCSP Package

The MAX4691–MAX4694 are low-voltage CMOS analog ICs configured as an 8-channel multiplexer (MAX4691), two 4-channel multiplexers (MAX4692), three single-pole/double-throw (SPDT) switches (MAX4693), and four SPDT switches (MAX4694).

The MAX4691/MAX4692/MAX4693 operate from either a single +2V to +11V power supply or dual ±2V to ±5.5V power supplies. When operating from ±5V supplies they offer 25Ω on-resistance (RON), 3.5Ω (max) RON flatness, and 3Ω (max) matching between channels. The MAX4694 operates from a single +2V to +11V supply. Each switch has rail-to-rail signal handling and a low 1nA leakage current.

All digital inputs are 1.8V logic-compatible when operating from a +3V supply and TTL compatible when operating from a +5V supply.

The MAX4691–MAX4694 are available in 16-pin, 4mm x 4mm QFN and TQFN and 16-bump UCSP packages. The chip-scale package (UCSP™) occupies a 2mm x 2mm area, significantly reducing the required PC board area.
