Analog Devices Inc./Maxim Integrated MAX4613ETE+T

Overview

MAX4613ETE+T 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, <5nA off-leakage at +85°C, 10pC max charge injection, and sub-250ns turn-on time - enabling precision signal routing in battery-powered test equipment and military radios.

For engineers reviewing the MAX4613ETE+T datasheet, MAX4613ETE+T pinout, MAX4613ETE+T application, or MAX4613ETE+T equivalent, this device supports rail-to-rail analog signal handling, TTL/CMOS logic compatibility, low-power operation (35µW max), and ESD tolerance of ≥2000V per Method 3015.7 - critical for ruggedized communication and guidance systems.

Technical Context

The MAX4613ETE+T implements four independent SPST switches using high-voltage CMOS process technology, with separate V+, V−, and VL pins enabling flexible logic-level translation and wide analog signal range (±15V with ±15V supplies). Its internal architecture guarantees matched on-resistance (≤4Ω between channels) and flat on-resistance (≤9Ω over full signal swing) only under bipolar-supply operation.

Switching is controlled by four independent digital inputs (IN1–IN4), each driving one switch pair (S/D terminals); logic thresholds are referenced to VL, supporting both TTL (VL = 5V) and CMOS (VL = V+) configurations. Break-before-make timing is guaranteed at 5–20ns, and crosstalk rejection exceeds 100dB at 1MHz between any two channels.

Key Specifications

Pinout & Package

MAX4613ETE+T uses a 16-pin Thin QFN package (5mm × 5mm) with exposed pad (EP) that must be connected to V+. The package supports high thermal efficiency and compact PCB layout for space-constrained portable systems.

FAQ

What is the maximum analog signal voltage range supported by the MAX4613ETE+T?

The MAX4613ETE+T supports an analog signal range of ±15V when operated with ±15V supplies, and 0V to +12V with +12V single supply. The absolute maximum analog voltage is limited by V+ and V− rails - signals must remain within (V− − 0.3V) to (V+ + 0.3V) to avoid clamping. This makes MAX4613ETE+T suitable for both legacy bipolar instrumentation and modern unipolar sensor interfaces.

Does the MAX4613ETE+T require external pull-up or pull-down resistors on its IN1–IN4 control lines?

No, the MAX4613ETE+T does not require external pull-up or pull-down resistors on IN1–IN4. Its logic inputs have guaranteed thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V at VL = 5V) and low input current (±0.5µA), allowing direct connection to microcontroller GPIOs or FPGA outputs. However, floating inputs must be avoided - unused INx pins should be tied to VL or GND to prevent erratic switching.

How is the exposed pad (EP) of the MAX4613ETE+T connected, and why is it critical?

The exposed pad (EP) of the MAX4613ETE+T must be soldered and electrically connected to V+. This connection provides primary thermal dissipation (enabling 2.667W max power at +70°C) and reduces ground bounce in high-speed switching. Failure to connect EP to V+ degrades thermal performance, increases junction temperature, and may cause premature failure under sustained load - a mandatory layout requirement for MAX4613ETE+T.

Can the MAX4613ETE+T operate with unbalanced supplies such as +24V and −5V?

Yes, the MAX4613ETE+T supports unbalanced supplies like +24V and −5V, as explicitly stated in its Applications Information section. The device requires only that |V+ − V−| ≤ +44V and that each supply remains within its absolute maximum rating (V+ ≤ +44V, V− ≥ −44V). This flexibility allows MAX4613ETE+T to interface directly with asymmetric power domains in avionics and industrial control systems.

What is the functional difference between the NC and NO switches in the MAX4613ETE+T?

The MAX4613ETE+T contains two normally closed (SW1, SW4) and two normally open (SW2, SW3) SPST switches. When INx = LOW, NC switches conduct and NO switches isolate; when INx = HIGH, the states reverse. This dual-mode topology enables fail-safe signal paths - for example, maintaining default audio routing (NC) while enabling diagnostic loopback (NO) - a key feature used in MAX4613ETE+T deployments in guidance and control systems.
