MAX4735：Low-Voltage, 0.31Ω, Quad-SPDT Analog Switch _ BDTIC a Leading Distributor in China

MAX4735：Low-Voltage, 0.31Ω, Quad-SPDT Analog Switch

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.
