Analog Devices Inc./Maxim Integrated MAX4613CSE

Overview

MAX4613CSE from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, 85Ω max R_DS(ON), 250ns max t_ON, and ±4.5V to ±20V bipolar or +4.5V to +40V single-supply operation-used in audio signal routing, test equipment, and battery-operated systems.

For engineers reviewing the MAX4613CSE datasheet, MAX4613CSE pinout, MAX4613CSE application, or MAX4613CSE equivalent, this page delivers verified electrical specs, real-world switching behavior, thermal leakage performance at +85°C, rail-to-rail analog handling, and TTL/CMOS logic compatibility-critical for precision analog multiplexing and low-distortion signal path design.

Technical Context

The MAX4613CSE implements four independent SPST switches with complementary logic control: IN1–IN4 directly drive each channel's gate, enabling simultaneous or selective switching. Its CMOS process ensures symmetrical conduction-identical R_DS(ON) in both source-to-drain and drain-to-source directions-and guarantees <5nA off-leakage at +85°C under bipolar supply conditions.

Switching is optimized for low charge injection (10pC max) and flat on-resistance (9Ω max variation across full ±15V analog range), making it suitable for sample-and-hold circuits where voltage settling and signal integrity are critical. The device supports unbalanced supplies (e.g., +24V/–5V) and requires VL tied to +5V for TTL-level inputs or to V+ for CMOS-level compatibility.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal range supported by the MAX4613CSE?

The MAX4613CSE supports an analog signal range of ±15V under bipolar supply conditions (V+ = +15V, V− = −15V) and 0V to +12V under single-supply operation (V+ = +12V, V− = GND). This rail-to-rail capability allows full-swing signal handling without clipping in audio, test, and military radio applications. Exceeding these limits risks damage due to internal diode clamping.

Does the MAX4613CSE require external level-shifting for TTL-compatible logic inputs?

No-the MAX4613CSE does not require external level-shifting for TTL-compatible logic inputs. When VL is connected to +5V, the IN1–IN4 pins accept standard TTL voltage thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V). This built-in compatibility eliminates need for discrete translators and simplifies interface with legacy microcontrollers and FPGAs operating at 5V logic levels.

How does the MAX4613CSE manage leakage current at elevated temperatures?

The MAX4613CSE guarantees off-leakage current of less than 5nA at +85°C-verified across all channels and tested at maximum rated hot temperature. This performance is achieved through optimized CMOS process design and is critical for maintaining accuracy in sample-and-hold circuits and high-impedance sensor interfaces where leakage-induced voltage drift degrades measurement fidelity.

Can the MAX4613CSE operate with unbalanced supply voltages such as +24V and −5V?

Yes-the MAX4613CSE supports unbalanced supply configurations like +24V and −5V, provided the absolute difference between V+ and V− does not exceed +44V and neither rail violates the Absolute Maximum Ratings (V+ ≤ +44V, V− ≥ −44V). This flexibility enables integration into legacy systems with asymmetric power domains without redesigning the supply architecture.

What is the role of the exposed pad (EP) on the MAX4613CSE narrow SO package?

The exposed pad (EP) on the MAX4613CSE narrow SO package is an internal thermal and electrical connection to the die substrate and must be soldered to V+. This improves thermal dissipation and reduces ground bounce during fast switching transitions. Leaving EP floating or connecting it to GND violates the recommended layout and may degrade ESD robustness and switching performance.
