Product details
Overview
The MAX4522EEE from Maxim Integrated is a quad, low-voltage, normally open (NO) single-pole/single-throw (SPST) analog switch IC. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 100Ω max on-resistance with ≤4Ω matching between channels, handles rail-to-rail analog signals, and exhibits only 1nA off-leakage at +25°C - ideal for precision signal routing in battery-powered test equipment.
For engineers reviewing the MAX4522EEE datasheet, MAX4522EEE pinout, MAX4522EEE application, or MAX4522EEE equivalent, this page provides verified specifications, QSOP-16 package details, TTL/CMOS-compatible logic thresholds, ESD-hardened design (>2kV), and real-world analog switching performance metrics including turn-on time (60–150 ns), charge injection (1–5 pC), and off-isolation (<−90 dB at 100 kHz).
Technical Context
The MAX4522EEE uses complementary CMOS (N- and P-channel) transistor pairs per switch, driven by level-translated logic inputs to enable rail-to-rail analog conduction. Its internal architecture includes reverse-biased ESD diodes between each analog pin and V+/V−, defining leakage paths and limiting signal excursion beyond supply rails.
It supports three power configurations: bipolar (±2V to ±6V), single-supply (+2V to +12V with V− tied to GND), and fully specified +2.7V operation. Logic inputs meet TTL/CMOS thresholds (0.8V/2.4V) across all supply modes, ensuring interoperability with standard digital controllers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| On-resistance match (ΔRON) | ≤4Ω max between channels - enables precise gain/phase matching in multi-channel instrumentation. |
| Rail-to-rail signal range | VCOM, VNO = V− to V+ - supports full dynamic range of sensors, DACs, and ADCs without clipping. |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance measurement circuits (e.g., pH sensors, photodiode amps). |
| Logic compatibility | TTL/CMOS thresholds (0.8V/2.4V) at ±5V or +5V supply - eliminates need for external level shifters in mixed-signal systems. |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive lab and field-deployed equipment. |
| Turn-on/off time | 60–150 ns / 20–75 ns (typ. at +5V) - suitable for multiplexing audio, data acquisition, and medium-speed control signals. |
Pinout & Package
MAX4522EEE is housed in a 16-pin QSOP (E16-4) package, 0.150" wide, 0.025" lead pitch, with exposed pad option not applicable to this variant. Pin 1 is NC (not connected); pins 2 and 5 are V− and GND respectively; pins 11 and 13 are V+ and COM2; all four INx/COMx/NOx terminals are arranged for compact PCB layout and signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (pins 15,14,7,6) | Digital control input | Active-high logic drives corresponding NO switch; compatible with 0.8V/2.4V thresholds at ±5V or +5V supply. |
| COM1–COM4 (pins 16,13,8,5) | Analog common terminal | Bidirectional signal path node - connects to source or load depending on system topology. |
| NO1–NO4 (pins 1,12,10,9) | Normally open analog output | Signal passes only when INx = high; electrically isolated from COMx when off (1nA leakage). |
| V+ (pin 11) | Positive supply | Powers analog switches and internal logic; internally connected to substrate; must be ≥2V above V−. |
| V− (pin 2) | Negative supply | Sets lower analog rail; connect to GND for single-supply use; reverse-biased ESD diodes clamp overvoltage. |
| GND (pin 3) | Digital ground reference | Reference for logic inputs only; no analog signal reference - analog paths float between V+ and V−. |
| N.C. (pin 4) | No connection | Not internally bonded; leave unconnected; no electrical function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPST NO configuration | Four independent analog switches with guaranteed break-before-make timing in shared-control applications. |
| Low on-resistance flatness | 12Ω max variation over full signal range - maintains consistent gain and linearity across ±4.5V analog swing. |
| Ultra-low power consumption | <1µW quiescent - extends battery life in portable DMMs, handheld analyzers, and IoT sensor nodes. |
| Pin compatibility | Drop-in replacement for DG212 - simplifies legacy system upgrades without PCB redesign. |
| High off-isolation | <−90 dB at 100 kHz - suppresses crosstalk between adjacent channels in dense multiplexer layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CSE | Same functionality, SO-16 package (S16-2), 0°C to +70°C temp range vs. −40°C to +85°C | Limited to commercial-grade environments; unsuitable for industrial or extended-temperature deployments | Select MAX4522CSE only for cost-sensitive, non-extended-temp designs where SO-16 footprint is preferred. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, ±15V supply capable, but higher 12µA supply current and no QSOP option | Higher voltage range suits industrial PLC I/O; higher leakage and power disqualify for ultra-low-power battery apps | Choose ADG1412BRUZ when ±15V operation or sub-2Ω RON is mandatory; avoid if QSOP footprint or <1µW power is required. |
Compared with MAX4522CSE, the MAX4522EEE offers extended temperature operation and QSOP packaging for space-constrained designs; versus ADG1412BRUZ, it trades higher voltage capability for significantly lower leakage, power, and footprint - making it optimal for portable, precision, and thermally demanding analog routing.

FAQ
What is the maximum supply voltage range supported by the MAX4522EEE?
The MAX4522EEE supports dual supplies from ±2V to ±6V (12V total) or a single supply from +2V to +12V. Absolute maximum ratings specify V+ to V− differential ≤13.0V, so ±6V supplies must account for tolerance margins. The MAX4522EEE is fully characterized down to +2.7V single supply, enabling ultra-low-power operation in coin-cell–powered devices.
Does the MAX4522EEE require external level-shifting when interfaced with 3.3V microcontrollers?
No - the MAX4522EEE features TTL/CMOS-compatible logic thresholds (0.8V low, 2.4V high) that are met directly by 3.3V GPIO outputs. When powered from +5V or ±5V supplies, the MAX4522EEE accepts standard 3.3V logic levels without external translation, simplifying integration with ARM Cortex-M or similar host processors.
How does the MAX4522EEE handle analog signals exceeding the supply rails?
The MAX4522EEE includes internal ESD-protection diodes between each analog pin (COM/NO) and both V+ and V−. If an analog signal exceeds V+ or falls below V−, the corresponding diode conducts, clamping the voltage. Users must limit forward diode current to ±10mA continuous or ±20mA pulsed to avoid damage - external series resistors are recommended for overvoltage protection.
Is the MAX4522EEE pin-compatible with industry-standard analog switches?
Yes - the MAX4522EEE is explicitly designed as a pin-compatible replacement for the DG212, sharing identical pinout, logic polarity, and functional behavior in QSOP-16 packaging. This allows direct substitution in existing DG212-based designs without layout changes, while delivering improved on-resistance matching (≤4Ω vs. typical 10Ω) and lower leakage.
What is the typical charge injection of the MAX4522EEE, and why does it matter?
The MAX4522EEE exhibits 1–5 pC typical charge injection - the transient charge dumped onto the signal path during switching. This matters in high-impedance sampling circuits (e.g., sample-and-hold, switched-capacitor filters), where injected charge causes voltage glitches and settling errors. At 1pC into a 1nF load, the glitch is only 1mV, supporting 12-bit+ accuracy in precision data acquisition using the MAX4522EEE.
