Analog Devices Inc./Maxim Integrated MAX4600EWE

Overview

MAX4600EWE from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.25Ω max R_ON match between channels, and 2.5nA max off-leakage at +85°C, enabling low-distortion switching in automatic test equipment and communication interfaces.

For engineers reviewing the MAX4600EWE datasheet, MAX4600EWE pinout, MAX4600EWE application, or MAX4600EWE equivalent, key selection criteria include its ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, TTL/CMOS-compatible logic thresholds, and guaranteed R_ON flatness of 0.3Ω over the full signal range.

Technical Context

The MAX4600EWE implements complementary MOSFET topologies per channel to achieve rail-to-rail analog signal handling across its full supply range. Its dual independent SPST architecture supports simultaneous but asymmetric control-Switch 1 is NC (logic low = ON), Switch 2 is NO (logic high = ON)-enabling flexible signal path configuration without external inversion.

Internal level-shifting circuitry ensures consistent TTL/CMOS input compatibility across all supported supply configurations, while ESD protection exceeds 2kV per Method 3015.7. The device maintains specified on-resistance matching and flatness under varying temperature (-40°C to +85°C) and signal voltage conditions.

Key Specifications

Pinout & Package

MAX4600EWE is housed in a 16-pin Wide SO (SOIC-W) package, 7.6mm × 10.3mm body, 1.27mm lead pitch, compliant with JEDEC MS-013. Pin 1 is located at the top-left corner adjacent to the index mark.

The MAX4580/MAX4590/MAX4600 family was engineered for low-distortion, high-reliability analog signal routing in environments where mechanical relays fail - targeting test instrumentation, telecom infrastructure, and precision data acquisition.

FAQ

What is the operating temperature range for the MAX4600EWE?

The MAX4600EWE is rated for operation from -40°C to +85°C, as indicated by the "E" suffix in the part number. This extended temperature grade makes it suitable for industrial and automotive under-hood applications where ambient conditions exceed commercial-grade limits. All electrical specifications-including on-resistance, leakage, and switching times-are guaranteed across this full range.

Does the MAX4600EWE support rail-to-rail analog signal switching?

Yes, the MAX4600EWE supports true rail-to-rail analog signal switching, meaning it can pass signals from V− to V+ without clipping or distortion. This capability is enabled by its CMOS process and internal charge-pump design, and is validated across its entire specified supply range (±4.5V to ±20V dual or +4.5V to +36V single). Signal integrity is preserved up to ±10V swing with <0.3Ω R_ON flatness.

How does the logic control scheme work for the two switches in the MAX4600EWE?

The MAX4600EWE features asymmetric logic control: Switch 1 (COM1/NC1) is normally closed and turns OFF when IN1 is high; Switch 2 (COM2/NO2) is normally open and turns ON when IN2 is high. This eliminates the need for external inverters in applications requiring one latching and one non-latching path-such as PBX line seizure and battery reversal detection. Both inputs accept standard TTL/CMOS thresholds.

Can the MAX4600EWE be used with a single +12V supply?

Yes, the MAX4600EWE operates reliably with a +12V single supply (V+ = +12V, V− = GND). In this configuration, VL must be supplied at +5V to maintain proper logic thresholds, and analog signals can swing from 0V to +12V. All key parameters-including 1.25Ω max R_ON, 2.5nA max off-leakage at +85°C, and 150ns turn-on time-remain fully specified and tested under single-supply conditions.

What package type is used for the MAX4600EWE?

The MAX4600EWE uses a 16-pin Wide SO (SOIC-W) package, measuring 7.6mm × 10.3mm with 1.27mm lead pitch. This package offers superior thermal dissipation versus standard SOIC and is compatible with standard surface-mount assembly processes. It is distinct from the SSOP and PDIP variants (e.g., MAX4600EAE, MAX4600EPE) and shares footprint compatibility with other wide-body Maxim analog switches.
