General Description
The MAX4740/MAX4740H low on-resistance (0.61Ω
typ) analog switches operate from a single 1.6V to 5.5V
supply. The MAX4740/MAX4740H are quad, single-
pole, double-throw (SPDT) switches and are configured
to route audio signals. The MAX4740/MAX4740H are
pin-to-pin compatible parts with the ST Microelectronics
quad SPDT STG3699 analog switch.
The MAX4740 is a quad SPDT switch and the
MAX4740H is a quad SPDT switch that can be placed
in a high-impedance mode. Switching logic is con-
trolled by 2 control bits (CB1 and CB2). The MAX4740/
MAX4740H also feature a low on-resistance match
(0.06Ω) and low power-supply current (0.3A), which
increases battery life.
The MAX4740/MAX4740H are available in a tiny 3mm x
3mm, 16-pin TQFN-EP, and 2.5mm x 2.5mm, 16-pin ultra-
thin QFN packages.
