Product details
Overview
MAX4523EGE from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for low-voltage signal routing in precision analog systems. It delivers 100Ω max on-resistance (±5V supplies), 4Ω max channel-to-channel on-resistance match, rail-to-rail signal handling, and <1µW power consumption. It is used in battery-operated test equipment requiring low-leakage, high-isolation switching of audio or sensor signals.
For engineers reviewing the MAX4523EGE datasheet, MAX4523EGE pinout, MAX4523EGE application, or MAX4523EGE equivalent, key selection criteria include its dual-supply (±2V to ±6V) or single-supply (+2V to +12V) flexibility, break-before-make timing (5–20ns), 2kV ESD protection, TTL/CMOS-compatible logic thresholds, and QFN-EP package thermal performance.
Technical Context
The MAX4523EGE implements four independent CMOS transmission gates-two NO and two NC-each driven by complementary N- and P-channel MOSFETs with logic-level translators isolating digital control from analog paths. Its internal architecture supports rail-to-rail analog operation by biasing switch gates with V+ and V−, enabling full-swing signal integrity without ground reference.
Signal path leakage is dominated by reverse-biased ESD diodes between each analog pin and V+/V−, resulting in temperature-dependent off-leakage (1nA @ +25°C, 10nA @ +85°C) and matched on-resistance flatness (12Ω max over signal range). Break-before-make timing is explicitly specified only for MAX4523 variants, confirming intentional channel separation during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision voltage routing |
| On-resistance match (ΔRON) | 4Ω max between channels - enables accurate differential or ratiometric measurements across switched paths |
| On-resistance flatness (RFLAT) | 12Ω max over signal range - maintains consistent gain and linearity across full analog input swing |
| Off-leakage current | 10nA max at +85°C - preserves signal integrity in high-impedance sensor or battery-monitoring circuits |
| Supply range | +2V to +12V single or ±2V to ±6V dual - supports portable, industrial, and avionics power architectures |
| Logic thresholds | VIN_L = 0.8V, VIN_H = 2.4V - guarantees interoperability with TTL and CMOS logic at +5V supply |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive test and field-deployable equipment |
Pinout & Package
The MAX4523EGE is housed in a 16-pin QFN-EP package (4mm × 4mm × 0.9mm) with exposed pad connected to V+. This thermally enhanced package supports higher continuous power dissipation (1349mW at +70°C) and improved thermal stability in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 | Digital control input | Active-high logic inputs controlling respective switch states; compatible with 0.8V/2.4V TTL/CMOS thresholds |
| COM1–COM4 | Analog common terminal | Bidirectional signal path hub - connects to either NO or NC terminal depending on logic state |
| NO1, NO4 | Normally open analog terminal | Connected to COM1/COM4 only when corresponding IN is high; isolated otherwise |
| NC2, NC3 | Normally closed analog terminal | Connected to COM2/COM3 when corresponding IN is low; disconnected when IN is high |
| V+ | Positive supply | Powers analog switches and internal logic; substrate tied internally; EP pad must be connected to V+ |
| V− | Negative supply | Sets lower analog signal limit; connect to GND for single-supply operation |
| GND | Digital ground reference | Reference for logic inputs only; no connection to analog signal paths |
| N.C. | No connection | Pins 10 and 12 are unconnected - leave floating or ground per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from V− to V+ without clipping or distortion, critical for audio and sensor front-ends |
| Break-before-make timing | 5–20ns delay prevents momentary shorting between NC and NO paths during transition - essential for safe multiplexer sequencing |
| Low charge injection (1–5pC) | Minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors), preserving ADC accuracy |
| Pin compatibility with DG211/DG212/DG213 | Enables drop-in replacement in legacy designs using industry-standard quad SPST switch footprints |
| 4 separately controlled SPST switches | Allows independent routing of four distinct analog signals - ideal for multi-channel data acquisition and signal conditioning |
Applications
| Battery-Operated Test Equipment | Avionics Signal Routing |

Use Value: Matched on-resistance (4Ω max) minimizes gain error between channels, enabling software calibration instead of per-channel hardware trimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522EGE | Four NO-only configuration; identical package, specs, and timing - differs only in default switch state | Requires redesign of control logic if NC functionality is needed; unsuitable where fail-safe closed-path is required | Select MAX4522EGE only when all four channels must be open-circuit by default |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical on-resistance, ±15V rating, but higher 15nA max off-leakage at +85°C and no BBM timing spec | Better for high-voltage industrial I/O; less suitable for ultra-low-leakage battery systems or sequenced NC/NO coordination | Choose ADG1412BRUZ when lower on-resistance outweighs leakage and timing control needs |
Compared with MAX4522EGE (NO-only) and ADG1412BRUZ (low-RON, high-voltage), MAX4523EGE uniquely provides mixed NO/NC topology with guaranteed break-before-make timing - making it optimal for fault-tolerant signal routing where both default-open and default-closed behavior are required within one IC.

FAQ
What is the operating temperature range for MAX4523EGE?
The MAX4523EGE is rated for −40°C to +85°C operation, as confirmed by its "E" grade suffix and ordering information table. This extended industrial temperature range ensures reliable performance in avionics, portable instrumentation, and outdoor industrial environments where ambient conditions exceed commercial-grade limits. The MAX4523EGE maintains specified on-resistance, leakage, and timing parameters across this full range.
Does MAX4523EGE support single-supply operation?
Yes, MAX4523EGE supports single-supply operation from +2V to +12V with V− connected to GND. Electrical characteristics are fully specified down to +2.7V, including 600Ω max on-resistance at +2.7V and guaranteed logic thresholds (0.8V/2.4V). This makes MAX4523EGE suitable for 3.3V and 5V systems without dual-rail generation.
What is the purpose of the exposed pad (EP) on MAX4523EGE?
The exposed pad (EP) on MAX4523EGE must be soldered and electrically connected to V+. It serves as the primary thermal path to the PCB, enabling 1349mW power dissipation at +70°C and improving thermal stability during sustained switching. Leaving EP unconnected or floating degrades thermal performance and may cause premature parametric drift or failure under load.
How does the break-before-make feature work in MAX4523EGE?
The break-before-make (BBM) timing in MAX4523EGE applies only to its mixed NO/NC configuration: when IN2 or IN3 toggles, the NC2/NC3 path opens *before* the NO2/NO4 path closes, with 5–20ns guaranteed delay. This prevents momentary shorting between normally closed and normally open paths - a critical safety feature in fault-tolerant routing where unintended conduction could compromise system integrity.
Is MAX4523EGE pin-compatible with older industry-standard switches?
Yes, MAX4523EGE is pin-compatible with DG211, DG212, and DG213 in the same 16-pin package footprint. This allows direct replacement in legacy designs without PCB revision. However, note that DG211/DG212/DG213 use DIP/SO packages, so mechanical adaptation (e.g., adapter board or layout update) is required when migrating to the QFN-EP package of MAX4523EGE.
