Analog Devices Inc./Maxim Integrated MAX4662EPE

Overview

MAX4662EPE from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 4Ω max on-resistance at +25°C, 0.4Ω max on-resistance matching between channels, and <0.7Ω on-resistance flatness over ±10V signal range. Its ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation supports high-voltage test equipment and industrial data acquisition.

For engineers reviewing the MAX4662EPE datasheet, MAX4662EPE pinout, MAX4662EPE application, or MAX4662EPE equivalent, key selection criteria include guaranteed channel-to-channel R_ON match, low charge injection (20pC typ), sub-5nA off-leakage at +85°C, TTL/CMOS-compatible control inputs with separate VL pin, and 16-pin plastic DIP package compatibility with legacy through-hole layouts.

Technical Context

The MAX4662EPE implements four independent CMOS SPST NO switches with fully differential analog signal handling capability across its full supply range. Each switch features matched P- and N-channel MOSFETs to achieve low and flat on-resistance, with internal level-shifting circuitry enabling logic compatibility regardless of analog supply voltage.

Its architecture guarantees break-before-make timing only in the MAX4663 variant - the MAX4662EPE has no break-before-make specification. The device uses a dedicated VL pin to decouple logic threshold references from analog supplies, ensuring reliable switching even when V+ and V− are asymmetric or widely separated.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in high-performance analog, mixed-signal, and power-management ICs for industrial, communications, and computing applications.

The MAX466x family was engineered for high-voltage, low-distortion analog signal routing in mission-critical test and measurement systems - prioritizing R_ON matching, rail-to-rail operation, and robust ESD tolerance over cost or density.

FAQ

What is the maximum allowable voltage difference between V+ and V− for MAX4662EPE?

The absolute maximum rating specifies V+ to V− must not exceed +44V. This allows safe operation at ±20V dual supply (40V total), with 4V margin for transient spikes. Exceeding this risks permanent damage to internal ESD structures and switch transistors. Always observe this limit during power-up sequencing and fault conditions in the MAX4662EPE design.

Does MAX4662EPE support break-before-make switching?

No, the MAX4662EPE does not feature guaranteed break-before-make timing. That functionality is exclusive to the MAX4663 variant. In the MAX4662EPE, simultaneous transition of multiple switches may cause momentary shorting between channels during logic transitions - avoid using it in applications requiring guaranteed isolation during reconfiguration.

Can MAX4662EPE operate with a 3.3V logic supply while using ±15V analog rails?

Yes. The dedicated VL pin allows direct connection to a 3.3V logic supply, while V+ and V− are set to ±15V. This maintains TTL/CMOS-compatible input thresholds (0.8V/2.4V) regardless of analog rail voltages - a key advantage over alternatives lacking independent logic supply pins like the MAX4662EPE.

What is the typical off-isolation performance of MAX4662EPE at 1MHz?

At 1MHz, the MAX4662EPE provides −56dB typical off-isolation (dual supply) and −60dB (single supply), measured with 50Ω source/load. This indicates <0.5% signal coupling from an off-switched channel to an active one - sufficient for 12-bit systems but insufficient for >14-bit precision without guard traces or shielding in layout.

Is the 16-pin plastic DIP package of MAX4662EPE RoHS-compliant?

Yes, the MAX4662EPE plastic DIP package meets RoHS Directive 2011/65/EU requirements. Lead content is restricted to <1000 ppm, and all six hazardous substances (Pb, Cd, Hg, Cr⁶⁺, PBB, PBDE) are within compliant limits. Full compliance documentation is available under Analog Devices' product change notices for the MAX4662EPE.
