Product details
Overview
MAX4612ESD+ from Maxim Integrated is a quad, low-voltage, SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, 100Ω max on-resistance at +5V, 4Ω max channel-to-channel on-resistance match, and rail-to-rail analog signal handling from V+ to GND. It operates from a single +2V to +12V supply and supports TTL/CMOS logic compatibility in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4612ESD+ datasheet, MAX4612ESD+ pinout, MAX4612ESD+ application, or MAX4612ESD+ equivalent, key selection criteria include guaranteed on-resistance flatness (18Ω max), <2nA off-leakage at +85°C, 300MHz on-channel bandwidth, and ESD protection >2kV per Method 3015.7 - all verified across the -40°C to +85°C industrial temperature range.
Technical Context
The MAX4612ESD+ implements four independent SPST switches using complementary MOSFET pairs per channel, enabling bidirectional analog signal routing without polarity constraints. Its architecture guarantees matched on-resistance (ΔRON ≤ 4Ω) and flat on-resistance (RFLAT(ON) ≤ 18Ω) over the full 0V to V+ signal range, critical for precision multiplexing and sample-and-hold accuracy.
Digital control inputs feature fixed +0.8V/2.4V thresholds for reliable TTL/CMOS interfacing at +5V, while internal ESD diodes provide >2kV HBM protection. The device handles rail-to-rail analog signals up to V+ = +12V, with leakage currents fully characterized and tested at maximum hot temperature (-40°C to +85°C).

| 13, 5, 6, 12 | IN1–IN4 | CMOS/TTL-compatible digital control inputs - drive switches with 0.8V/2.4V thresholds |
| 7 | GND | Digital ground reference - must be tied to system ground for proper logic threshold operation |
| 14 | V+ | Positive supply for analog and digital circuitry - bypass with 0.1µF capacitor near pin for stability |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612EUD+ | Same electrical specs, TSSOP-14 package (U14+1) instead of SO-14 (S14+2) | Requires different land pattern and reflow profile; higher thermal resistance than SO | Select for space-constrained layouts where TSSOP footprint is preferred |
| ADG1412BRUZ | Lower on-resistance (1.8Ω typ), wider supply (±15V), but higher leakage (20nA @ +85°C) | Supports bipolar signal routing and higher voltage rails, unsuitable for ultra-low-leakage sample-and-hold | Select when ±15V operation or sub-2Ω RON is required, accepting higher leakage trade-off |
Compared with MAX4612EUD+, the MAX4612ESD+ offers identical switching performance in a narrower SO package better suited for wave-soldered industrial assemblies; compared with ADG1412BRUZ, it trades lower leakage and smaller footprint for higher on-resistance - making it optimal for battery-powered, low-leakage, single-supply systems.

FAQ
What is the maximum supply voltage rating for MAX4612ESD+?
The absolute maximum V+ rating for MAX4612ESD+ is +13V referenced to GND. Operation at +12V is fully specified with 45Ω max on-resistance and 300MHz bandwidth. Exceeding +13V risks permanent damage, and designers must ensure supply transients or noise spikes do not breach this limit - especially when using ±10% tolerant 12V sources.
Does MAX4612ESD+ support rail-to-rail analog signal switching?
Yes, MAX4612ESD+ supports true rail-to-rail analog signal handling from 0V to V+. This is confirmed in the Electrical Characteristics table (Analog Signal Range = 0 to V+) and applies across the full −40°C to +85°C operating range. No external biasing or level-shifting circuitry is needed when interfacing with ADCs or DACs operating at the same supply rail.
What is the on-resistance match specification for MAX4612ESD+ and how is it measured?
MAX4612ESD+ guarantees ΔRON ≤ 4Ω max between any two channels, defined as RON(max) − RON(min) measured under identical conditions (V+ = +5V, ICOM = 1mA, VNO/VNC = 3V, TA = +25°C). This parameter is 100% tested and ensures predictable gain tracking in multi-channel sensor interfaces.
Can MAX4612ESD+ be used with a +3V supply, and what performance changes occur?
Yes, MAX4612ESD+ operates down to +2V supply. At +3V, on-resistance increases to 360Ω max (vs. 100Ω at +5V), turn-on time extends to 140ns max, and off-leakage remains ≤2nA at +85°C. Input logic thresholds remain valid (+0.5V low, +2.4V high), preserving compatibility with 3.3V microcontrollers without level translation.
Is MAX4612ESD+ pin-compatible with industry-standard analog switches like the 74HC4066?
Yes, MAX4612ESD+ is pin-compatible with the 74HC4066 and MAX4066 in the 14-pin SO package. Pin assignments for COMx, NOx/NCx, INx, V+, and GND align directly - enabling drop-in replacement where improved on-resistance matching, lower leakage, and rail-to-rail operation are required without PCB redesign.
