Analog Devices Inc./Maxim Integrated MAX4613EPE

Overview

The MAX4613EPE 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, 250ns max t_ON, and 70ns max t_OFF, enabling precision signal routing in battery-powered test equipment and audio systems.

For engineers reviewing the MAX4613EPE datasheet, MAX4613EPE pinout, MAX4613EPE application, or MAX4613EPE 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 rugged industrial and military-grade signal switching designs.

Technical Context

The MAX4613EPE implements four independent SPST switches using high-voltage CMOS process technology, supporting both unipolar and bipolar supply configurations. Its internal architecture guarantees matched on-resistance (≤4Ω between channels) and flat on-resistance (≤9Ω over full signal range) only under bipolar-supply operation, as explicitly specified in the datasheet.

Each switch features bidirectional conduction, break-before-make timing (5–20ns), and low capacitive loading (16pF on-state, 4pF off-state). Logic control inputs are referenced to VL (5V), while analog paths operate across V+ and V− rails - requiring careful sequencing (V+ first) to avoid latch-up or overvoltage damage.

Key Specifications

Pinout & Package

MAX4613EPE uses a 16-pin plastic DIP package with through-hole mounting and exposed substrate connection via pin 13 (V+). Pin 5 is GND; pins 1/8/9/16 are logic inputs (IN1–IN4); pins 2/7/10/15 are drain terminals (D1–D4); pins 3/6/11/14 are source terminals (S1–S4); pin 4 is V−; pin 12 is VL (logic supply); pin 13 is V+.

FAQ

What is the maximum analog signal voltage range supported by the MAX4613EPE?

The MAX4613EPE supports an analog signal range of ±15V under bipolar supply conditions (V+ = +15V, V− = −15V) and 0V to +12V under single-supply operation (V− = GND, V+ = +12V). This range scales with supply voltage: up to ±20V with bipolar ±20V supplies, or up to +40V with unipolar +40V operation - always staying within the absolute maximum ratings of V+ to V− ≤ +44V.

Does the MAX4613EPE require external pull-up or pull-down resistors on its logic inputs?

No, the MAX4613EPE does not require external pull-up or pull-down resistors on IN1–IN4. Its TTL/CMOS-compatible inputs have guaranteed thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V) and low input current (±0.5µA max), allowing direct connection to microcontroller GPIOs or FPGA outputs. However, floating inputs must be avoided - unused control lines should be tied to VL or GND.

How does the MAX4613EPE handle power-supply sequencing, and what happens if V+ is applied after logic inputs?

The MAX4613EPE requires strict power-supply sequencing: V+ must be applied first, followed by VL, then V−, and finally logic inputs. If logic signals arrive before V+ is stable, internal protection diodes may conduct, causing excessive current or latch-up. The datasheet recommends adding external series diodes on V+ and V− pins if sequencing cannot be guaranteed - though this reduces usable analog range by ~1V.

Can the MAX4613EPE be used in a single-supply configuration with V− grounded, and how does that affect performance?

Yes, the MAX4613EPE operates in single-supply mode with V− tied to GND and V+ set between +4.5V and +40V. In this configuration, the analog signal range becomes 0V to (V+ − 1V), on-resistance increases slightly (e.g., 200Ω max at V+ = +12V), and leakage remains <5nA at +85°C. Rail-to-rail operation is preserved, but bipolar signal handling is lost.

Is the MAX4613EPE pin-compatible with the industry-standard DG213 analog switch?

Yes, the MAX4613EPE is explicitly designed as a pin-compatible replacement for the DG213, sharing identical pinout, function mapping, and package dimensions in DIP, SO, and TSSOP variants. This allows drop-in substitution in legacy designs without PCB modification - provided the MAX4613EPE's improved specs (lower leakage, tighter R_ON match, higher ESD rating) align with system requirements.
