Analog Devices Inc./Maxim Integrated MAX4601EPE

Overview

MAX4601EPE from Maxim Integrated is a quad, single-pole single-throw (SPST), normally closed (NC) analog switch IC operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supply. It delivers 2.5Ω max on-resistance, 0.5Ω max on-resistance match between channels, and rail-to-rail analog signal handling up to ±10V. Used in automatic test equipment for reed relay replacement, it supports low-distortion audio-signal routing and high-reliability avionics switching.

For engineers reviewing the MAX4601EPE datasheet, MAX4601EPE pinout, MAX4601EPE application, or MAX4601EPE equivalent, key selection criteria include guaranteed R_ON flatness (0.5Ω max over signal range), −40°C to +85°C industrial temperature rating, 16-pin plastic DIP package, and TTL/CMOS-compatible logic thresholds (0.8V/2.4V) with <2.5nA off-leakage at +85°C.

Technical Context

The MAX4601EPE implements four independent CMOS SPST switches with normally closed topology-each COM terminal connects to its NC terminal when the control input is logic low. Its architecture uses matched P- and N-channel MOSFETs to achieve low and flat on-resistance across the full analog signal range (±10V).

It features dual-supply capability (±4.5V to ±20V) and single-supply operation (+4.5V to +36V), with separate VL pin for logic-level referencing. All digital inputs are TTL/CMOS-compatible, and internal ESD protection exceeds 2000V per Method 3015.7.

Key Specifications

Pinout & Package

MAX4601EPE is housed in a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB layouts and socketing for prototyping and production test fixtures.

FAQ

What is the maximum analog signal voltage range supported by the MAX4601EPE?

The MAX4601EPE supports rail-to-rail analog signals from V− to V+, enabling operation across ±10V with ±15V supplies or 0V to +36V with single +36V supply. Absolute maximum ratings allow V+ to GND up to +44V and V− to GND down to −44V, but functional analog range is bounded by supply rails. The MAX4601EPE maintains guaranteed R_ON flatness within ±10V of COM, ensuring linearity in precision applications.

Does the MAX4601EPE require a separate logic supply voltage?

Yes - the MAX4601EPE has a dedicated VL pin (Pin 12) that must be connected to a stable logic reference, typically +5V, to set TTL/CMOS-compatible input thresholds (0.8V low, 2.4V high). This decouples logic-level definition from analog supplies (V+ and V−), allowing independent optimization of analog headroom and digital interface robustness. The MAX4601EPE will not function correctly if VL is left unconnected or tied directly to V+ or GND.

Can the MAX4601EPE be used with a single +12V supply?

Yes - the MAX4601EPE operates from a single +4.5V to +36V supply. For +12V operation, connect V− to GND (Pin 4), V+ to +12V (Pin 13), GND to system ground (Pin 5), and VL to +5V (Pin 12). Electrical characteristics including 2.5Ω max R_ON, 0.5Ω max R_ON match, and <2.5nA off-leakage are fully specified and guaranteed under this configuration per the datasheet's "Single +12V Supply" section.

How does the MAX4601EPE differ from the MAX4602EPE and MAX4603EPE?

The MAX4601EPE contains four normally closed (NC) SPST switches, while the MAX4602EPE has four normally open (NO) switches, and the MAX4603EPE integrates two NC and two NO switches in one package. All three share identical electrical specs (R_ON, leakage, supply range, logic thresholds), pinout, and package - only the default switch state differs. Thus, MAX4601EPE is selected when default-closed signal paths are required, such as fail-safe sensor monitoring or power-on signal continuity.

Is the MAX4601EPE pin-compatible with other packages in the same family?

Yes - the MAX4601EPE (16-pin plastic DIP), MAX4601EAE (16-pin SSOP), and MAX4601EWE (16-pin wide SO) share identical pin functions and numbering. Signal names (IN1–IN4, COM1–COM4, NC1–NC4, V+, V−, VL, GND) map identically across all three packages. However, mechanical layout, thermal performance, and soldering methods differ significantly - DIP supports through-hole prototyping and socketing, while SSOP and SO require SMT reflow.
