MAX4735
Low-Voltage, 0.31Ω, Quad-SPDT Analog Switch
|
Status
Active: In Production.
Description
The MAX4735 quad-SPDT switch routes audio signals
in portable applications. Each channel has a 0.31Ω typical
on-resistance, allowing the MAX4735 to drive 8Ω loudspeakers with less than 0.02% distortion.
The MAX4735 is configured as a quad-SPDT switch with
two common control inputs. Each digital input controls
two pairs of SPDT switches. The switches are fully bidirectional,
allowing both multiplexing and demultiplexing
operation. Break-before-make operation is guaranteed.
The device operates from a +1.6V to +3.6V supply and
over the extended -40°C to +85°C temperature range. It
is offered in both 16-pin 3mm x 3mm TQFN and TSSOP
packages.
