Analog Devices Inc./Maxim Integrated MAX4613CUE

Overview

MAX4613CUE from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for precision signal routing in rail-to-rail ±15V or +12V systems. It delivers 70Ω max on-resistance at +25°C, <5nA off-leakage at +85°C, 10pC max charge injection, and sub-250ns turn-on time-enabling high-fidelity audio routing and sample-and-hold circuits.

For engineers reviewing the MAX4613CUE datasheet, MAX4613CUE pinout, MAX4613CUE application, or MAX4613CUE equivalent, key selection criteria include guaranteed R_ON matching (≤4Ω), bipolar/single-supply flexibility (+4.5V to +40V or ±4.5V to ±20V), TTL/CMOS logic compatibility, low power consumption (35µW max), and ESD tolerance (2000V min per Method 3015.7).

Technical Context

The MAX4613CUE implements four independent CMOS transmission-gate switches with separate IN1–IN4 control inputs and dual supply rails (V+, V−). Its internal architecture ensures symmetrical conduction-identical R_DS(ON) performance regardless of signal direction-and guarantees flat on-resistance (≤9Ω variation) across the full ±15V analog range under bipolar operation.

Switching is controlled by TTL/CMOS-compatible logic levels referenced to VL (typically +5V), with break-before-make timing (5–20ns) preventing transient short-circuits. The device features integrated ESD protection diodes and supports unbalanced supplies (e.g., +24V/−5V), provided |V+ − V−| ≤ 44V.

Key Specifications

FAQ

What supply configurations does the MAX4613CUE support?

The MAX4613CUE operates from a single +4.5V to +40V supply (with V− tied to GND) or bipolar ±4.5V to ±20V supplies. Unbalanced configurations like +24V/−5V are also supported, provided |V+ − V−| ≤ 44V. VL must be set to +5V for TTL compatibility or to V+ for CMOS logic levels. This flexibility makes MAX4613CUE suitable for both industrial power rails and legacy telecom systems.

How does the MAX4613CUE handle normally open versus normally closed switching behavior?

The MAX4613CUE integrates two normally open (SW1, SW4) and two normally closed (SW2, SW3) SPST switches within one die. Logic polarity differs per pair: SW1/SW4 activate on logic low (IN1/IN4 = 0V), while SW2/SW3 activate on logic high (IN2/IN3 = VL). This dual-mode configuration enables fail-safe signal routing-e.g., default connection to backup sensor (NC) unless overridden by primary path (NO)-without external logic inversion.

Is the MAX4613CUE pin-compatible with other industry-standard analog switches?

Yes, the MAX4613CUE is explicitly pin-compatible with the industry-standard DG213, sharing identical pinout, function mapping, and electrical interface. This allows direct replacement in existing designs without layout changes, preserving signal integrity and reducing qualification time. However, MAX4613CUE improves upon DG213 with lower off-leakage (<5nA vs. typical 20nA), tighter R_ON matching (4Ω vs. 10Ω), and enhanced ESD rating (2000V vs. 1000V).

What is the significance of the exposed pad (EP) on the MAX4613CUE TSSOP package?

The exposed pad (EP) on the MAX4613CUE TSSOP package must be soldered and electrically connected to V+. This connection serves three critical functions: it lowers thermal resistance for improved power dissipation (2667mW max at +70°C), stabilizes the silicon substrate potential to minimize noise coupling, and enhances ESD robustness by providing a low-impedance path to the positive rail. Failure to connect EP to V+ risks thermal overload and degraded switching performance.

Can the MAX4613CUE be used in high-temperature environments beyond +70°C?

No-the MAX4613CUE is rated for 0°C to +70°C operation only ('C' grade). For extended temperature applications (−40°C to +85°C), the MAX4613EUE variant must be used. While MAX4613CUE leakage remains below 5nA at +85°C per characterization data, its R_DS(ON), timing, and logic thresholds are not guaranteed outside the specified 0°C to +70°C range. Using MAX4613CUE beyond its rated temperature violates reliability specifications and voids warranty coverage.
