MAX4599 Low-Voltage, Single-Supply, I: 3 j E 2%: I: j
General Description
The MAX4599 single-pole/double-throw (SPDT) switch
operates from a +2.0V to +5.5V single supply. It offers
60Ω max on-resistance (RON) at +5V and fast switching
times (tON = 30ns max, tOFF = 25ns max).
The MAX4599 features excellent RON flatness (4Ω max)
and matching (1Ω max) between channels. This device
also offers 5pC max charge injection.
The MAX4599 is available in tiny 6-pin SC70, μDFN, and
SOT23 packages.

Applications Information
Analog Signal Levels
Analog signals can range over the supply voltage (V+
to GND) with on-resistance changing very little over the
entire range (see Typical Operating Characteristics). The
MAX4599 is bidirectional, so the NO, NC, and COM pins
can be used either as inputs or outputs.
Power-Supply Sequencing and
Overvoltage Protection
Proper power-supply sequencing is recommended for all
CMOS devices. Always apply V+ before applying analog
signals or logic inputs, especially if the analog or logic sig-
nals are not current limited. If this sequencing is not pos-
sible, and if the analog or logic inputs are not current lim-
ited to < 20mA, add a small-signal diode (D1) as shown in
Figure 1. If the analog signal can dip below GND, add D2.
Adding protection diodes reduces the analog signal range
to a diode drop (about 0.7V) below V+ for D1 or to a diode
drop above ground for D2. The addition of diodes does
not affect leakage. On-resistance increases by a small
amount at low supply voltages. Maximum supply voltage
(V+) must not exceed 6V.
Protection diodes D1 and D2 also protect against some
overvoltage situations. A fault voltage up to the absolute
maximum rating at an analog signal input does not dam-
age the device, even if the supply voltage is below the
signal voltage.
