MAX4758/MAX4759
Quad DPDT Audio/Data Switches in UCSP/QFN

Detailed Description
The MAX4758/MAX4759 quad DPDT analog switches
operate from a single +1.8V to +5.5V supply. These
devices are fully specified for +3V applications.
The MAX4758/MAX4759 (switches 1–4) have a guaran-
teed 0.5
Ω on-resistance, making them ideal for audio
switching applications. The MAX4759 also includes four
single-pole/double-throw (SPDT) switches (switches
5–8) that have a guaranteed 0.2
Ω on-resistance, a low
25pF capacitance, 0.2ns change in skew making them
ideal for either data or audio switching applications.
These switches have four logic inputs to control two
switches in pairs.
Applications Information
Digital Control Inputs
The MAX4758/MAX4759 logic inputs accept up to
+5.5V regardless of the supply voltage. For example,
with a +3.3V supply, IN_ can be driven low to GND and
high to +5.5V, which allows mixed logic levels in a sys-
tem. Driving the control logic inputs rail-to-rail also mini-
mizes power consumption. For a +3V supply voltage,
the logic thresholds are 0.5V (low) and 1.4V (high).
Analog Signal Levels
Analog signal inputs over the full voltage range (0V to V+)
are passed through the switch with minimal change in on-
resistance (see the Typical Operating Characteristics).
The switches are bidirectional so NO_, NC_, and COM_
can be either inputs or outputs.
Power-Supply Bypassing
Power-supply bypassing improves noise margin and
prevents switching noise from propagating from the V+
supply to other components. A 0.1F capacitor connect-
ed from V+ to GND is adequate for most applications.
Power-Supply Sequencing
CMOS devices require proper power-supply sequenc-
ing. Always apply V+ before the analog signals, espe-
cially if the input signal is not current limited. If
sequencing is not possible, and the input signal is not
current limited to less than 20mA, add a small-signal
diode (Figure 1). Adding the diode reduces the analog
range to a diode drop (0.7V) below V+ and increases
the on-resistance slightly. The maximum supply voltage
must not exceed +6V at any time.
