Product details
Overview
MAX4523EEE from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for rail-to-rail signal routing in low-voltage systems. It features 100Ω max on-resistance (±5V supplies), 4Ω max channel-to-channel RON matching, <1nA COM off-leakage at +25°C, and operates from ±2V to ±6V dual or +2V to +12V single supply - enabling use in battery-powered audio routing and precision data acquisition.
For engineers reviewing the MAX4523EEE datasheet, MAX4523EEE pinout, MAX4523EEE application, or MAX4523EEE equivalent, key selection criteria include verified break-before-make timing (5–20 ns), TTL/CMOS-compatible logic thresholds (+0.8V/2.4V), ESD robustness (>2kV per Method 3015.7), and QSOP-16 package compatibility with industry-standard DG211/DG212 footprints.
Technical Context
The MAX4523EEE implements complementary N- and P-channel MOSFETs per switch, driven by level-translated logic inputs to support rail-to-rail analog signals up to V+ and down to V−. Its internal architecture ensures matched on-resistance flatness (12Ω max over signal range) and low charge injection (1–5 pC), critical for sample-and-hold and multiplexed ADC front-ends.
Unlike MAX4521 (all-NC) and MAX4522 (all-NO), the MAX4523EEE integrates mixed NO/NC topology across four independent channels - pins 1/16 (NO1/NO4) and 14/11 (NC2/NC3) - enabling simultaneous signal path selection and fail-safe default routing in avionics and test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation in 50Ω–600Ω impedance interfaces. |
| RON matching | ≤4Ω max between channels - preserves gain/phase balance in multi-channel instrumentation. |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - maintains accuracy in high-impedance sensor nodes and µA-level bias networks. |
| Supply range | +2V to +12V single or ±2V to ±6V dual - supports operation from Li-ion batteries (3.0–3.7V) to industrial ±5V rails. |
| Logic thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS interfacing without external level shifters at +5V supply. |
| Break-before-make delay | 5–20 ns (typ. 10 ns) - prevents momentary shorting during channel switching in audio crosspoints. |
| ESD protection | >2kV per Method 3015.7 - enables direct handling in production environments without special grounding. |
Pinout & Package
MAX4523EEE is housed in a 16-pin QSOP (E16-4) package, 0.150" wide, 0.025" lead pitch, with gull-wing leads and no exposed pad. Pin 1 is NC (not connected); pins 2 and 5 are V− and GND respectively; pins 11 and 13 are V+ and COM2; functional pin mapping follows standard MAX4523 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1–IN4 | Digital control inputs - drive internal level translators; accept TTL/CMOS logic regardless of supply configuration. |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - bidirectional signal ports; connect to source or load depending on routing need. |
| 3, 6 | NO1, NO4 | Normally open analog terminals - conduct only when corresponding INx = logic high; used for active-path selection. |
| 14, 11 | NC2, NC3 | Normally closed analog terminals - conduct when INx = logic low; provide default signal continuity during power-up/fault. |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower bound of analog signal range. |
| 5 | GND | Digital ground reference - isolated from analog paths; required for logic interface stability and ESD return path. |
| 12 | N.C. | No connection - internally unconnected; must be left floating or grounded per PCB layout best practices. |
| 13 | V+ | Positive analog/digital supply - powers both switch core and logic; internally tied to substrate for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NO/NC topology | Two independently controlled NO and two NC switches enable fault-tolerant signal routing without external latching. |
| Rail-to-rail analog handling | Signals swing from V− to V+ - supports full-scale ±4.5V differential inputs in dual-supply mode or 0–5V in single-supply mode. |
| Low on-resistance flatness | 12Ω max variation across ±4.5V signal range - minimizes harmonic distortion (<0.1% THD at 10kHz) in audio paths. |
| Ultra-low power consumption | <1µW quiescent power - extends battery life in portable DMMs and handheld test gear operating at 3.3V. |
| Pin compatibility | Direct drop-in replacement for DG211/DG212/DG213 - allows legacy design upgrades without PCB rework. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522EEE | All four channels are NO (vs. MAX4523EEE's 2NO/2NC); identical RON, leakage, and timing specs. | Suitable where all paths require active-enable behavior; lacks fail-safe NC default routing capability. | Select MAX4522EEE only when system design mandates uniform NO topology and no default-path requirement exists. |
| ADG1412BRUZ | Higher RON (1.8Ω typ. at ±15V, but 120Ω at ±5V), wider supply (±5V to ±22V), no BBM timing spec. | Better for high-voltage industrial I/O; unsuitable for low-leakage, low-distortion audio or precision sensor apps. | Choose ADG1412BRUZ only when operating above ±10V supplies is required; avoid for battery-powered or audio-critical designs. |
Compared with MAX4522EEE (all-NO) and ADG1412BRUZ (high-voltage), the MAX4523EEE uniquely delivers mixed NO/NC functionality with sub-5pC charge injection and guaranteed break-before-make timing - making it the only choice for safety-critical, low-distortion, and battery-efficient routing where default path integrity matters.

FAQ
What is the maximum analog signal range supported by the MAX4523EEE?
The MAX4523EEE supports rail-to-rail analog signals from V− to V+. With ±5V dual supplies, this equals ±4.5V; with +5V single supply (V− = GND), it spans 0V to +4.5V. The device clamps signals exceeding V+ or V− via internal ESD diodes - limiting absolute analog input to (V− − 0.3V) to (V+ + 0.3V) per Absolute Maximum Ratings.
Does the MAX4523EEE require external pull-up or pull-down resistors on its digital inputs?
No. The MAX4523EEE has internally defined TTL/CMOS-compatible logic thresholds (+0.8V low, +2.4V high) that function reliably with standard +5V or ±5V logic drivers. External biasing is unnecessary unless interfacing with open-drain or high-impedance sources where noise immunity is critical.
Can the MAX4523EEE operate from a single +3.3V supply?
Yes. The MAX4523EEE is fully specified for single +2.7V to +3.6V operation. At +3.3V, typical on-resistance is 260Ω, turn-on time is 250ns, and logic thresholds remain within +0.8V/+2.4V - enabling direct integration into 3.3V microcontroller-based data loggers and portable sensors.
How does the break-before-make timing of the MAX4523EEE prevent signal shorting?
The MAX4523EEE guarantees 5–20 ns break-before-make delay between NO and NC channels during logic transitions. This ensures the previously active path opens before the new path closes - eliminating momentary shorts in audio crosspoints or sensor redundancy switching where signal integrity is critical.
Is the MAX4523EEE pin-compatible with the DG212 analog switch?
Yes. The MAX4523EEE shares identical pinout, footprint, and electrical behavior with the DG212 in QSOP-16 packaging. Both devices feature four SPST switches, compatible logic thresholds, and similar RON and leakage specs - allowing direct replacement without PCB modification.
