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™).
