MAX4662EAE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4662EAE+T is a quad single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 2.5Ω with guaranteed matching of 0.5Ω and flatness of 0.5Ω across the signal range. It supports rail-to-rail analog signals, operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, and includes TTL/CMOS-compatible logic inputs via a separate VL pin. The device offers low off-leakage current of 5nA max at +85°C, >2kV ESD protection, and is housed in a 16-pin SSOP package for an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm authenticity. Ensure the ordering suffix matches the required temperature grade (-40°C to +85°C) and package type (16 SSOP). Cross-reference the manufacturer part number with authorized distributors to validate sourcing channels and avoid counterfeit components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise resistance matching are critical. The MAX4662 provides four normally open switches, distinguishing it from the MAX4661 (normally closed) and MAX4663 (mixed configuration). Ensure the application requires the specific 2.5Ω on-resistance and that the power supply constraints align with the single or dual supply capabilities.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4661/MAX4662/MAX4663 family of quad SPST CMOS analog switches. While sharing core electrical characteristics like low on-resistance and rail-to-rail operation, the MAX4662 specifically features four normally open switches. This distinguishes it from the MAX4661, which has four normally closed switches, and the MAX4663, which combines two NC and two NO switches with break-before-make timing.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4662 and MAX4663?

The MAX4662 contains four normally open (NO) switches. In contrast, the MAX4663 features two normally closed (NC) and two normally open (NO) switches, and it guarantees break-before-make switching timing.

How does the logic supply pin (VL) function?

The separate VL pin allows the control logic to operate independently of the analog supply rails. This design guarantees TTL/CMOS logic compatibility regardless of whether the analog switches are powered by a single supply up to 36V or dual supplies up to ±20V.

What is the maximum off-leakage current specification?

The off-leakage current is specified as a maximum of 5nA at an ambient temperature of +85°C. This low leakage makes the device suitable for high-impedance signal paths.
