MAX4729 Datasheet, PDF (1/9 Pages) Maxim Integrated Products – Low-Voltage 3.5ohm, SPDT, CMOS Analog Switches

19-3284; Rev 0; 5/04
Low-Voltage 3.5Ω, SPDT,
CMOS Analog Switches
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_ON), as well as 0.45Ω R_ON 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.
