Analog Devices Inc./Maxim Integrated MAX4538ESE

Overview

The MAX4538ESE from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, common enable pin, ±2V to ±6V dual or +2V to +12V single supply operation, 200Ω max on-resistance, rail-to-rail signal handling, and 100ns turn-on time at ±4.5V - used in audio-signal routing and low-voltage data acquisition systems.

For engineers reviewing the MAX4538ESE datasheet, MAX4538ESE pinout, MAX4538ESE application, or MAX4538ESE equivalent, this page delivers verified electrical specs, truth-table-validated switching behavior, package-specific thermal derating, leakage performance across temperature, and real-world dynamic timing under ±4.5V/±5V and +4.5V supply conditions.

Technical Context

The MAX4538ESE implements four independently controlled CMOS transmission gates with complementary N- and P-channel MOSFETs per channel, driven by logic-level translators that convert TTL/CMOS inputs into full-rail gate drive signals referenced to V+ and V−. Its break-before-make timing (15ns typ, 50ns max) is explicitly specified only for the MAX4538 variant and ensures no momentary short between NC and NO paths during state transitions.

Internal ESD protection diodes connect each analog pin (COM/NO/NC) to both V+ and V−, limiting analog signal range to V− ≤ V_SIGNAL ≤ V+, and causing supply-dependent leakage currents. Logic thresholds scale with V+ (e.g., 0.8V–2.4V at +5V; ~0.9V–2.0V at +3V), enabling compatibility across 3V, 5V, and 12V single-supply systems.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range for the MAX4538ESE?

The MAX4538ESE is rated for -40°C to +85°C operation, validated across all electrical parameters including on-resistance flatness, leakage current, and switching times. This extended temperature grade makes it suitable for automotive cabin electronics, industrial sensors, and outdoor test equipment where ambient extremes are expected. The "E" suffix explicitly denotes the -40°C to +85°C range, distinguishing it from the "C" grade (0°C to +70°C).

Does the MAX4538ESE support single-supply operation?

Yes, the MAX4538ESE operates from a single +2V to +12V supply when V− is connected to GND. At +4.5V, it delivers 200Ω max on-resistance and 125ns/60ns t_ON/t_OFF; at +3V, R_ON rises to 600Ω max but retains rail-to-rail signal handling. Logic thresholds automatically scale (e.g., 0.5V–2.0V at +3V), ensuring reliable TTL/CMOS interface without external level shifters.

How does the MAX4538ESE differ from the MAX4536ESE and MAX4537ESE?

The MAX4538ESE integrates two normally open (NO) and two normally closed (NC) switches in one package, whereas MAX4536ESE contains four NO switches and MAX4537ESE contains four NC switches. Only the MAX4538ESE implements break-before-make timing (15ns typ) between its paired NC/NO channels - critical for preventing signal shorts in relay-replacement and analog mux applications requiring fault-tolerant path selection.

What is the significance of the "ESE" suffix in MAX4538ESE?

The "ESE" suffix identifies the MAX4538ESE as the -40°C to +85°C temperature-grade device in a 16-pin narrow SO package. "E" = extended temperature, "S" = narrow SO (JEDEC MS-012), "E" = lead-free and RoHS-compliant finish. This distinguishes it from MAX4538EEE (QSOP) and MAX4538EPE (PDIP), all sharing identical electrical specifications but differing in package form factor and thermal characteristics.

Can the MAX4538ESE be used with ±12V supplies?

No - the absolute maximum V+ to V− differential is 13.0V. While ±6V (12V total) is within spec, ±12V would exceed the 13.0V limit and risk permanent damage. Even ±6V supplies with ±10% tolerance (up to ±6.6V = 13.2V) violate the rating. For higher voltage operation, consider the MAX318 or ADG series, which support ±15V rails with appropriate derating.
