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

0.5

Ω on-resistance for audio switching and a low 25pF

capacitance for data switching.

The MAX4758 has eight 0.5

Ω on-resistance switches to

switch audio signals. The MAX4759 has four 0.5

Ω 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™).
