General Description

The 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 (R

), as well as 0.45Ω R

flatness with

a +2.7V supply. These devices typically consume only

1nA of supply current, making them ideal for use in low-

power, portable applications. The MAX4729/MAX4730

feature low-leakage currents over the extended temper-

ature 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.

MAX4729/MAX4730 Low-Voltage 3.5Ω, SPDT, CMOS Analog Switches General Description Features The 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.
