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

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.

o Tiny SC70 and µDFN Packages
o -3dB Bandwidth: 300MHz
o Low On-Capacitance: 19.5pF
o 0.036% Total Harmonic Distortion
o Low Supply Current: 1nA
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.

Note 1: Signals on NO, NC, or COM exceeding V+ or GND are clamped by internal diodes. Signals on IN exceeding GND are
clamped by an internal diode. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

low-power, portable applications. The MAX4729/
MAX4730 feature low-leakage currents over the entire
temperature range, TTL/CMOS-compatible digital logic,

Caution: Do not exceed the absolute maximum ratings
because stresses beyond the listed ratings can cause
permanent damage to the device. Proper power-supply
sequencing is recommended for all CMOS devices.
Always apply V+ before applying analog signals, espe-
cially if the analog signal is not current limited.
