Analog Devices Inc./Maxim Integrated MAX4613ESE

Overview

MAX4613ESE from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, operating from +4.5V to +40V single supply or ±4.5V to ±20V bipolar supplies. It delivers 85Ω max on-resistance at +25°C, <5nA off-leakage at +85°C, and 10pC max charge injection-enabling precision signal routing in battery-operated test equipment and military radios.

For engineers reviewing the MAX4613ESE datasheet, MAX4613ESE pinout, MAX4613ESE application, or MAX4613ESE equivalent, this device supports rail-to-rail analog signal handling, TTL/CMOS logic compatibility, sub-250ns turn-on time, and ESD tolerance ≥2000V-critical for high-reliability analog switching in harsh environments.

Technical Context

The MAX4613ESE implements four independent SPST switches with complementary logic control: IN1–IN4 directly drive each channel's gate, enabling simultaneous or selective switching. Its internal architecture ensures matched R_DS(ON) ≤4Ω between channels and flat on-resistance ≤9Ω across the full ±15V analog range under bipolar operation.

Switching is bidirectional with symmetric conduction, supported by low 16pF on-capacitance (CD(ON)/CS(ON)) and high 100dB crosstalk rejection at 1MHz. The device requires VL = +5V for TTL compatibility or connection to V+ for CMOS-level inputs, and mandates V+ sequencing before VL/V− to prevent latch-up.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal range supported by the MAX4613ESE?

The MAX4613ESE supports ±15V analog signals under bipolar supply conditions (V+ = +15V, V− = −15V) and 0–12V under single-supply operation (V+ = +12V, V− = GND). This rail-to-rail capability ensures compatibility with standard op-amp output stages and high-voltage DACs without external level-shifting circuitry.

Does the MAX4613ESE require external pull-up resistors on its IN1–IN4 pins?

No, the MAX4613ESE does not require external pull-up resistors on IN1–IN4. Its logic inputs are TTL/CMOS compatible when VL = +5V, accepting 0.8V low and 2.4V high thresholds. Internal input structure ensures proper switching without external biasing-simplifying PCB layout and reducing BOM count.

Can the MAX4613ESE operate with unbalanced supplies like +24V and −5V?

Yes, the MAX4613ESE supports unbalanced supplies such as +24V and −5V, provided the absolute difference between V+ and V− does not exceed +44V and each rail stays within its Absolute Maximum Rating (V+ ≤ +44V, V− ≥ −44V). This flexibility enables custom power architectures in avionics and industrial control systems.

How does the exposed pad on the MAX4613ESE package function?

The exposed pad on the MAX4613ESE's narrow SO package must be connected to V+ to ensure proper thermal dissipation and substrate biasing. This connection reduces thermal resistance and stabilizes the internal CMOS switch threshold-critical for maintaining R_DS(ON) consistency and ESD robustness across temperature.

Is the MAX4613ESE pin-compatible with the industry-standard DG213?

Yes, the MAX4613ESE is pin-compatible with the DG213, sharing identical pin assignments for IN1–IN4, D1–D4, S1–S4, V+, V−, GND, and VL. This allows direct replacement in legacy designs without PCB modification-retaining existing layout while upgrading to lower leakage, tighter R_ON matching, and enhanced ESD tolerance.
