Analog Devices Inc./Maxim Integrated MAX4662CAE+T

Overview

MAX4662CAE+T from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, 2.5Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±10V. It delivers matched on-resistance (≤0.5Ω), flat on-resistance (≤0.5Ω), and <5nA off-leakage at +85°C - ideal for precision data acquisition and reed-relay replacement in test equipment.

For engineers reviewing the MAX4662CAE+T datasheet, MAX4662CAE+T pinout, MAX4662CAE+T application, or MAX4662CAE+T equivalent, key selection criteria include guaranteed R_ON matching across channels, TTL/CMOS-compatible logic inputs with separate VL pin, low charge injection (20pC typical), and ESD robustness (>2kV per Method 3015.7).

Technical Context

The MAX4662CAE+T implements four independent CMOS SPST NO switches with fully differential analog signal paths. Each switch features a dedicated COM and NO terminal, controlled by individual digital inputs (IN1–IN4), and shares common V+, V−, VL, and GND connections. Its architecture supports rail-to-rail analog voltage swing without distortion, enabled by symmetric N- and P-channel MOSFET pairing and matched threshold design.

Operation is decoupled across supply domains: analog path operates from V+ and V− (or V+ and GND), while logic interface uses VL referenced to GND - ensuring consistent switching thresholds regardless of analog supply level. The device guarantees break-before-make only in MAX4663 variants; MAX4662CAE+T has no break-before-make timing specification.

Key Specifications

Pinout & Package

MAX4662CAE+T is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, 5.0mm × 6.2mm body size, and exposed pad not connected internally. This RoHS-compliant package supports surface-mount assembly and provides thermal performance suitable for continuous 200mA per switch operation.

FAQ

What is the operating temperature range for MAX4662CAE+T?

The MAX4662CAE+T is rated for commercial temperature operation from 0°C to +70°C. This grade is validated across all electrical specifications in that range, including R_ON, leakage, and switching times. For extended industrial use (−40°C to +85°C), the MAX4662EAE+T variant is specified and tested accordingly.

Does MAX4662CAE+T support break-before-make switching?

No, MAX4662CAE+T does not feature guaranteed break-before-make timing. That functionality is exclusive to the MAX4663 variant. MAX4662CAE+T implements standard SPST NO switching with no intentional overlap or gap between channel transitions - users must manage timing externally if simultaneous conduction must be avoided.

Can MAX4662CAE+T operate from a single +5V supply?

Yes, MAX4662CAE+T supports single-supply operation down to +4.5V. With V+ = +5V and V− = GND, it handles rail-to-rail analog signals from 0V to +5V. Logic inputs remain compatible via VL pin, which may be tied to +3.3V or +5V depending on controller voltage - ensuring reliable switching without level shifters.

What is the maximum continuous current per switch in MAX4662CAE+T?

The MAX4662CAE+T supports ±200mA continuous current through each COM–NO path. This rating applies across the full temperature range and supply conditions. Peak pulsed current up to ±300mA is allowed at 1ms duration and 10% duty cycle, provided power dissipation remains within package limits (571mW for SSOP at +70°C).

How is logic compatibility maintained across wide analog supply ranges in MAX4662CAE+T?

MAX4662CAE+T achieves logic compatibility across wide analog supplies via its dedicated VL pin, which independently biases the input stage. Regardless of whether V+ is +12V or +36V, the INx inputs respond to standard TTL/CMOS thresholds (0.8V low, 2.4V high) referenced to VL - eliminating supply-dependent logic margin issues and simplifying interface design.
