MAX4599EXT-T
Low-Voltage / Single-Supply / SPDT Analog Switch in SC70
General DescriptionThe MAX4599 single-pole/double-throw (SPDT) switch
operates from a +2.0V to +5.5V single supply. It offers
60Ωmax on-resistance (RON) at +5V and fast switching
times (tON= 30ns max, tOFF= 25ns max).
The MAX4599 features excellent RON flatness (4Ωmax)
and matching (1Ωmax) between channels. This device
also offers 5pC max charge injection.
The MAX4599 is available in tiny 6-pin SC70 and SOT23
packages.

Applications Information
Analog Signal LevelsAnalog 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 ProtectionProper 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 signals are not current limited. If this sequenc-
ing is not possible, and if the analog or logic inputs are
not current limited 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 sup-
ply 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 damage the device, even if the supply voltage
is below the signal voltage.
