Analog Devices Inc./Maxim Integrated MAX4052AESE+

Overview

MAX4052AESE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It supports ±2.7V to ±8V dual supplies or +2.7V to +16V single supply, delivers 100Ω max on-resistance at ±5V, 6Ω channel-to-channel on-resistance match, and 0.1nA off-leakage at +25°C - enabling precision signal selection in battery-powered data acquisition and audio routing.

For engineers reviewing the MAX4052AESE+ datasheet, MAX4052AESE+ pinout, MAX4052AESE+ application, or MAX4052AESE+ equivalent, key selection criteria include guaranteed on-resistance flatness, rail-to-rail analog signal handling, TTL/CMOS logic compatibility, and A-suffix characterization for leakage and matching across temperature.

Technical Context

The MAX4052AESE+ implements two independent 4-channel analog multiplexers with address-controlled channel selection (ADDA/ADDB) and global inhibit (INH). Each switch features complementary CMOS transmission gates with matched P- and N-channel devices, ensuring symmetrical on-resistance and low distortion (<0.04% at 600Ω).

Its logic interface accepts 0.8V–2.4V thresholds for TTL/CMOS compatibility across supply voltages, while internal level translators drive analog switches directly from V+ and V−, isolating digital control from analog signal paths. No GND reference is required for analog signals - they operate strictly between V+ and V− rails.

FAQ

What is the maximum analog signal range supported by the MAX4052AESE+?

The MAX4052AESE+ supports rail-to-rail analog signals between V− and V+. With ±5V supplies, this means −5V to +5V; with +5V single supply (V− = GND), it supports 0V to +5V. The device tolerates signals up to (V− − 2V) and (V+ + 2V) due to internal ESD diodes, but sustained operation outside V− to V+ risks increased leakage and distortion. Always constrain analog signals within the supply rails for specified performance.

Does the MAX4052AESE+ require external pull-up or pull-down resistors on its address pins?

No, the MAX4052AESE+ does not require external pull-up or pull-down resistors on ADDA, ADDB, or INH. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) and draw only ±1µA input current at V+ or GND. Microcontroller GPIOs driving these pins directly meet logic level and current requirements - eliminating external bias components and reducing BOM count.

Can the MAX4052AESE+ be used with a +3.3V single supply?

Yes, the MAX4052AESE+ operates with a +3.3V single supply (V+ = +3.3V, V− = GND). At this voltage, typical on-resistance rises to ~350Ω (max 700Ω), and turn-on time increases to ~300ns. Leakage remains at 0.1nA, and logic thresholds scale appropriately. Confirm signal swing stays within 0V to +3.3V and verify timing margins in your application - especially for high-speed multiplexing.

How does the MAX4052AESE+ handle break-before-make timing during channel switching?

The MAX4052AESE+ guarantees a minimum break-before-make delay (tOPEN) of 30ns at +25°C with ±5V supplies. This prevents momentary shorting between channels during address transitions, protecting downstream circuitry from transient currents. The value increases slightly at temperature extremes and lower supplies - e.g., 90ns at +3V. For critical applications, verify timing with actual address slew rates and load conditions using Figure 4 test setup.

Is thermal shutdown or overcurrent protection built into the MAX4052AESE+?

No, the MAX4052AESE+ does not include thermal shutdown or overcurrent protection. It relies on external design safeguards: absolute maximum ratings limit continuous current per terminal to ±30mA and peak pulsed current to ±100mA (1ms, 10% duty cycle). Exceeding these risks permanent damage. Designers must ensure analog signal levels, source impedance, and load conditions keep switch conduction losses within safe power dissipation limits for the SOIC-N package (696mW at +70°C).
