Dual SPDT Analog Switches with

Over-Rail Signal Handling

General Description

Features

The MAX4850/MAX4850H/MAX4852/MAX4852H family

of dual SPDT (single-pole/double-throw) switches oper-

ate from a single +2V to +5.5V supply and can handle

signals greater than the supply rail. These switches fea-

ture low 3.5Ω or 3.5Ω/7Ω on-resistance with low on-

capacitance, making them ideal for switching audio

and data signals.

ꢀ USB 2.0 Full Speed (12MB) and USB 1.1 Signal

Switching Compliant

ꢀ Switch Signals Greater than V

ꢀ 0.1ns Differential Skew

ꢀ 3.5Ω/7Ω On-Resistance

ꢀ 135MHz -3dB Bandwidth

ꢀ +2V to +5.5V Supply Range

ꢀ 1.8V Logic Compatible

The MAX4850/MAX4850H are configured with two

SPDT switches and feature two comparators for head-

phone detection or mute/send key functions. The

MAX4852 has two SPDT switches with no comparators

for low 1µA supply current.

ꢀ Low Supply Current

1µA (MAX4852)

5µA (MAX4850)

10µA (MAX4850H/MAX4852H)

ꢀ Available in a Space-Saving (3mm x 3mm),

For over-rail applications, these devices offer either the

pass-through or high-impedance option. For the

MAX4850/MAX4852, the signal (up to 5.5V) passes

through the switch without distortion even when the posi-

tive supply rail is exceeded. For the MAX4850H/

MAX4852H, the switch input becomes high impedance

when the input signal exceeds the supply rail.

16-Pin TQFN Package

The MAX4850/MAX4850H/MAX4852/MAX4852H are

available in the space-saving (3mm x 3mm), 16-pin

TQFN package and operate over the extended temper-

ature range of -40°C to +85°C.
