模拟开关 IC 3.5Ohm Dual SPST Analog Switch

Low-Voltage 3.5Ω, SPDT,  CMOS Analog Switches

General Description

The MAX4729EXT+T MAX4729/MAX4730 single-pole/double-throw (SPDT) switches operate from a single supply ranging from +1.8V to +5.5V. These switches provide low 3.5Ω on-resistance (RON), as well as 0.45Ω RON flatness with a +2.7V supply. These devices typically consume only 1nA of supply current, making them ideal for use in lowpower, portable applications. The MAX4729/MAX4730 feature low-leakage currents over the extended temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics.

The MAX4729/MAX4730 are available in small 6-pin  SC70 and 6-pin μDFN packages. The MAX4729/  MAX4730 are offered in three pinout configurations to  ease design. The MAX4729/MAX4730 are specified  over the extended -40°C to +85°C temperature range.
