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, designed for precision signal routing in mixed-signal systems. It delivers 85Ω max on-resistance at +25°C, <5nA off-leakage at +85°C, and 10pC max charge injection - enabling low-distortion sample-and-hold and audio routing in battery-powered and industrial test equipment.

For engineers reviewing the MAX4613CSE+ datasheet, MAX4613CSE+ pinout, MAX4613CSE+ application, or MAX4613CSE+ equivalent, this device supports rail-to-rail analog signals up to ±15V (bipolar) or 0–12V (unipolar), features TTL/CMOS-compatible logic inputs, and operates across +4.5V to +40V single supply or ±4.5V to ±20V dual supplies - critical for robust switching in communication systems and guidance control.

Technical Context

The MAX4613CSE+ implements four independent SPST switches with complementary logic control: IN1/IN4 drive NO switches (S1/D1, S4/D4), while IN2/IN3 drive NC switches (S2/D2, S3/D3). Its CMOS process ensures symmetrical conduction, with guaranteed R_ON matching ≤4Ω between channels and flatness ≤9Ω over full signal range under bipolar operation.

Switching performance is optimized for low transient error: t_ON <250ns and t_OFF <70ns at ±10V, supported by low parasitic capacitance (C_S(ON)/C_D(ON) = 16pF, C_S(OFF)/C_D(OFF) = 4pF) and high off-isolation rejection (60dB at 1MHz), making it suitable for high-fidelity audio routing and fast data acquisition.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range for the MAX4613CSE+?

The MAX4613CSE+ is rated for commercial temperature operation from 0°C to +70°C, as indicated by the 'C' suffix in its part number. This range is validated per Maxim's ordering information table and applies to all electrical specifications unless otherwise noted in the datasheet's temperature columns. The MAX4613CSE+ maintains guaranteed on-resistance match (≤4Ω), charge injection (≤10pC), and leakage (<5nA at +85°C derated) within this range. For extended industrial use, consider the MAX4613ESE variant rated from –40°C to +85°C.

Does the MAX4613CSE+ support unbalanced dual supplies such as +24V and –5V?

Yes, the MAX4613CSE+ explicitly supports unbalanced dual supplies per its Applications Information section. The device requires only that the absolute difference between V+ and V– does not exceed +44V, and each supply remains within its respective absolute maximum rating (V+ ≤ +44V, V– ≥ –44V). Operation at +24V/–5V is valid and preserves full analog signal range from –5V to +24V, provided VL is set appropriately for logic compatibility. This capability is confirmed in the "Operation with Supply Voltages Other than ±15V" subsection.

How is the VL pin used in the MAX4613CSE+?

The VL pin on the MAX4613CSE+ sets the logic threshold voltage for the IN1–IN4 control inputs. Connecting VL to +5V configures the device for TTL-compatible operation (logic high ≥2.4V), while tying VL to V+ enables CMOS-level compatibility (logic high ≥V+ × 0.7). This flexibility eliminates external level-shifting circuitry when interfacing with mixed-voltage controllers. The VL pin must not float and must remain within (GND – 0.3V) to (V+ + 0.3V) per Absolute Maximum Ratings.

What is the significance of the exposed pad (EP) on the MAX4613CSE+ package?

The exposed pad (EP) on the MAX4613CSE+'s narrow SO package is an internal thermal and electrical connection to the die substrate, designated to be soldered and connected directly to V+ for optimal thermal performance. Per Maxim's pin description and package diagram, EP improves power dissipation - especially critical under continuous conduction - and reduces thermal resistance by up to 30% compared to non-EP variants. It must not be left floating or grounded, as doing so violates the specified connection requirement and risks latch-up or degraded ESD performance.

Can the MAX4613CSE+ be used in a single-supply configuration with V– tied to GND?

Yes, the MAX4613CSE+ supports single-supply operation with V– connected to GND, as documented in the "ELECTRICAL CHARACTERISTICS-Single Supply" section. In this mode, the analog signal range is 0V to V+, with V+ ranging from +4.5V to +40V. All key parameters - including R_DS(ON) (200Ω max at V+ = 12V), charge injection (10pC max), and leakage (<5nA at +85°C) - remain guaranteed. The device retains rail-to-rail capability relative to the single supply, and VL must still be configured for logic compatibility (e.g., VL = +5V).
