MAX4661EAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4661EAE is a quad, single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin SSOP package. It features four normally closed switches with a maximum on-resistance of 2.5Ω and a maximum on-resistance match between channels of 0.5Ω. The device operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. Electrical characteristics include a maximum off-leakage current of 5nA at +85°C, a typical turn-on time of 275ns, and a typical turn-off time of 175ns under dual supply conditions. The operating temperature range extends from -40°C to +85°C.

• Audio-signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EAE' corresponds to the -40°C to +85°C temperature range and 16-pin SSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure power-supply sequencing adheres to absolute maximum ratings to prevent permanent damage during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are required for analog signal routing. The MAX4661 is specifically designed for applications necessitating normally closed default states. Evaluate thermal dissipation requirements based on the 571mW power rating in the SSOP package. Consider the separate logic supply pin for level shifting if interfacing with varying logic voltages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4661/MAX4662/MAX4663 family of quad analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4661 variant is distinguished by its four normally closed switch configuration, contrasting with the normally open MAX4662 and the mixed break-before-make MAX4663. All variants share identical electrical performance metrics regarding on-resistance and leakage currents.
