Quad DPDT Audio/Data Switches in UCSP/QFN
General Description
The MAX4758/MAX4759 quad double-pole/double-
throw (DPDT) analog switches operate from a single
+1.8V to +5.5V supply. These switches feature low
0.5Ω on-resistance for audio switching and a low 25pF
capacitance for data switching.
The MAX4758 has eight 0.5Ω on-resistance switches to
switch audio signals. The MAX4759 has four 0.5Ω on-
resistance switches to route audio signals and four
25pF capacitance switches to route data signals. The
MAX4758/MAX4759 have four logic inputs to control the
switches in pairs.
The MAX4758/MAX4759 are available in a small 36-pin
(6mm x 6mm) thin QFN and 36-bump (3mm x 3mm)
chip-scale package (UCSP™).

Note 1:
Signals on NO_, NC_, COM_ exceeding V+ or GND are clamped by internal diodes. 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.

Note 2:
The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3:
UCSP packages are 100% tested at +25°C and limits across the full temperature range are guaranteed by correlation and
design. Thin QFN parts are 100% tested at +85°C and limits across the full temperature range are guaranteed by correla-
tion and design.
