Analog Devices Inc./Maxim Integrated MAX4662EAE+

Overview

MAX4662EAE+ from Maxim Integrated is a quad, single-pole single-throw (SPST), normally open (NO) analog switch IC operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supply. It delivers 2.5Ω max on-resistance, 0.5Ω max R_ON match between channels, and rail-to-rail analog signal handling up to ±10V. Used in test equipment and data acquisition systems where low distortion and mechanical relay replacement are critical.

For engineers reviewing the MAX4662EAE+ datasheet, MAX4662EAE+ pinout, MAX4662EAE+ application, or MAX4662EAE+ equivalent, key selection criteria include guaranteed R_ON flatness (0.5Ω max), <5nA off-leakage at +85°C, TTL/CMOS-compatible logic inputs with separate VL pin, and 16-pin SSOP package with -40°C to +85°C industrial temperature rating.

Technical Context

The MAX4662EAE+ implements four independent CMOS SPST NO switches with matched channel characteristics. Its architecture supports rail-to-rail analog signal switching across the full supply range while maintaining low charge injection (20pC typ) and high off-isolation (-56dB typ at 1MHz).

It features a dedicated VL logic supply pin enabling TTL/CMOS compatibility regardless of analog supply voltage, and internal protection diodes clamp input signals exceeding V+ or V−. The device guarantees break-before-make timing only in the MAX4663 variant-this function is absent in MAX4662EAE+.

Key Specifications

Pinout & Package

MAX4662EAE+ is housed in a 16-pin shrink small-outline package (SSOP) with 0.65mm lead pitch, rated for -40°C to +85°C operation. The package provides compact footprint and thermal performance suitable for dense PCB layouts in automated test and data acquisition systems.

FAQ

What is the maximum analog signal voltage range supported by the MAX4662EAE+?

The MAX4662EAE+ supports rail-to-rail analog signals from V− to V+, meaning it handles ±10V differential signals with ±15V supplies or 0V to +36V with single +36V supply. Absolute maximum ratings allow V+ to GND up to +44V and V− to GND down to -44V, but operational signal range is constrained by supply rails. This capability makes MAX4662EAE+ suitable for interfacing with op-amps, sensors, and DACs operating across wide voltage domains.

Does the MAX4662EAE+ support break-before-make switching?

No, the MAX4662EAE+ does not feature guaranteed break-before-make switching. That function is exclusive to the MAX4663 variant, which integrates internal timing control to ensure one switch opens before another closes. The MAX4662EAE+ implements four independent SPST NO switches with no inter-channel timing coordination - users must manage sequencing externally if overlap-free switching is required in their design.

Can the MAX4662EAE+ operate with a 3.3V logic supply while using ±15V analog supplies?

Yes, the MAX4662EAE+ supports this configuration via its dedicated VL pin. Connecting VL to 3.3V establishes TTL/CMOS-compatible input thresholds (VIN_H ≈ 2.4V, VIN_L ≈ 0.8V) while V+ and V− remain at ±15V. This eliminates need for external level shifters and maintains full rail-to-rail analog signal handling - a key advantage of MAX4662EAE+ in mixed-voltage systems like industrial PLC I/O modules.

What is the typical charge injection of the MAX4662EAE+ and why does it matter?

The MAX4662EAE+ exhibits 20pC typical charge injection, measured as the net charge transferred to the COM terminal during switching transitions. This parameter directly impacts accuracy in sample-and-hold circuits and high-impedance sensor interfaces: excessive charge injection causes voltage glitches on hold capacitors or bias nodes. At 20pC, MAX4662EAE+ enables stable sampling of signals into ≥1nF capacitors with sub-1mV error - critical for 16-bit+ data acquisition systems.

How does the on-resistance flatness specification affect signal fidelity in audio applications?

The MAX4662EAE+ guarantees R_ON flatness of 0.5Ω maximum over the full ±10V signal range, meaning its resistance variation stays within ±0.5Ω regardless of instantaneous signal voltage. In audio routing, this ensures consistent gain and phase response across the entire waveform - preventing harmonic distortion and intermodulation that would arise from nonlinear R_ON modulation. Combined with low 2.5Ω nominal R_ON, this delivers THD performance suitable for professional-grade analog signal paths.
