Analog Devices Inc./Maxim Integrated MAX4513CSE

Overview

MAX4513CSE from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, fault-protected up to ±36V with ±15V supplies or ±40V with power off, 175Ω max on-resistance, rail-to-rail signal handling, and TTL/CMOS-compatible logic inputs - used in industrial data acquisition systems requiring robust signal routing under overvoltage transients.

For engineers reviewing the MAX4513CSE datasheet, MAX4513CSE pinout, MAX4513CSE application, or MAX4513CSE equivalent, key selection criteria include fault protection voltage limits, dual/single-supply operation range (±4.5V to ±18V or +9V to +36V), channel configuration (2×NC + 2×NO), break-before-make timing (50–100 ns), and leakage performance (0.5 nA @ +25°C).

Technical Context

The MAX4513CSE employs parallel N- and P-channel FET architecture per channel, enabling low on-resistance and true rail-to-rail conduction. Its internal fault-protection circuitry uses dual comparators monitoring NO_/NC_ pins against V+ and V−, disabling signal paths and activating booster FETs (capable of ±10mA) during overvoltage events.

Unlike traditional triple-FET fault-protected switches, it maintains stable on-resistance across the full signal range and delivers glitch-free clamped outputs during fault onset/cessation. It supports break-before-make timing only in the MAX4513 variant (50–100 ns), critical for avoiding momentary shorts in redundant signal paths.

FAQ

What is the maximum fault voltage the MAX4513CSE can withstand on its NC_/NO_ pins?

The MAX4513CSE withstands ±36V faults on NC_/NO_ pins when powered with ±15V supplies, and ±40V when fully unpowered. This is explicitly tested and guaranteed per Absolute Maximum Ratings. Exceeding these limits - even briefly - risks permanent damage. The COM_ and IN_ pins are not fault-protected and must remain within V− to V+.

Does the MAX4513CSE support single-supply operation, and what is the valid voltage range?

Yes, the MAX4513CSE supports single-supply operation with V− connected to GND and V+ ranging from +9V to +36V. Electrical characteristics including on-resistance (up to 525Ω max), leakage (≤0.5nA @ +25°C), and logic thresholds remain valid across this range. Operation below +9V is not characterized or guaranteed.

How does the break-before-make timing work in the MAX4513CSE, and is it guaranteed?

The MAX4513CSE implements break-before-make timing exclusively between its two NO channels (IN3/IN4 → NO3/NO4) and two NC channels (IN1/IN2 → NC1/NC2), with a guaranteed 50–100 ns delay measured from 50% of turn-off to 50% of turn-on. This timing is production-tested and ensures no overlap during switching - critical for avoiding shorts in redundant signal paths.

Can the MAX4513CSE be used as a direct replacement for DG201/DG202/DG213 switches?

Yes, the MAX4513CSE is pin-compatible with DG201 (quad NC), DG202 (quad NO), and DG213 (dual NC + dual NO), and shares identical pinout and footprint. However, only the NC_/NO_ pins inherit fault protection - COM_ and IN_ pins retain standard CMOS behavior. No PCB changes are needed, but system-level fault analysis must confirm NC_/NO_ placement aligns with protection goals.

What is the on-resistance matching between channels in the MAX4513CSE, and why does it matter?

The MAX4513CSE guarantees on-resistance matching of ≤10Ω max between any two channels at ±15V supplies. This tight matching ensures consistent gain and offset across multiplexed signal paths - essential for precision instrumentation, ratiometric measurements, and differential signal routing where channel-to-channel tracking directly impacts measurement accuracy.
