Product details
Overview
MAX4523ESE 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 delivers 100Ω max on-resistance at ±5V supplies, 4Ω max channel-to-channel RON matching, and <1nA COM off-leakage at +25°C - enabling precision signal path control in battery-powered data acquisition and audio routing.
For engineers reviewing the MAX4523ESE datasheet, MAX4523ESE pinout, MAX4523ESE application, or MAX4523ESE equivalent, key selection criteria include its dual-supply (±2V to ±6V) or single-supply (+2V to +12V) operation, break-before-make timing (5–20ns), TTL/CMOS-compatible logic thresholds, and pin compatibility with DG211/DG212/DG213.
Technical Context
The MAX4523ESE integrates four independent CMOS SPST switches with complementary N- and P-channel MOSFETs per channel, driven by logic-level translators that convert TTL/CMOS inputs into full-rail gate drive signals referenced to V+ and V−. Its internal ESD protection diodes clamp analog signals exceeding supply rails, limiting safe operating range to (V− − 0.3V) to (V+ + 0.3V).
Switch behavior is defined by discrete logic states: IN1/IN4 control NO1/NO4 (active-high), while IN2/IN3 control NC2/NC3 (active-low). The device exhibits flat on-resistance (12Ω max variation over signal range) and low charge injection (0.5–5pC), critical for sample-hold and multiplexed ADC front-ends.
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 analog paths. |
| RON matching | ≤4Ω max between channels - enables matched gain/attenuation across multiplexed sensor or audio channels. |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - preserves accuracy in high-impedance sensor interfaces and battery-critical standby modes. |
| Supply range | +2V to +12V single or ±2V to ±6V dual - supports operation from Li-ion batteries (3.0–4.2V) up to industrial ±5V rails. |
| Logic thresholds | VIN_L ≤ 1.6V, VIN_H ≥ 1.6V - guarantees reliable switching with 3.3V/5V TTL and CMOS logic without level shifters. |
| Break-before-make delay | 5–20ns (typ. 10ns) - prevents momentary shorting during channel switching in mixed-signal routing applications. |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive test and avionics environments. |
Pinout & Package
MAX4523ESE is supplied in a 16-pin narrow SO (SOIC-N) package (S16-2), 3.9mm × 9.9mm body, 1.27mm pitch, with gull-wing leads and exposed pad not present (non-QFN variant).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1–IN4 | Digital control inputs: IN1/IN4 enable NO1/NO4 (high = ON); IN2/IN3 enable NC2/NC3 (low = ON). |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - bidirectional signal ports connected to NO or NC pins when switched. |
| 3, 6 | NO1, NO4 | Normally open analog terminals - conduct to COM1/COM4 only when respective IN1/IN4 = high. |
| 14, 11 | NC2, NC3 | Normally closed analog terminals - conduct to COM2/COM3 when respective IN2/IN3 = low. |
| 4 | V− | Negative analog supply input - connect to GND for single-supply operation; sets lower analog signal limit. |
| 5 | GND | Digital ground reference - no analog signal reference; isolates logic domain from analog signal paths. |
| 12 | N.C. | No internal connection - must be left unconnected; not usable as thermal pad or auxiliary node. |
| 13 | V+ | Positive analog/digital supply - powers internal logic translators and switch gates; internally tied to substrate. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V− to V+ without clipping - supports full dynamic range of ±5V op-amps or 0–5V microcontroller ADCs. |
| Low power consumption | <1µW quiescent - enables always-on signal routing in energy-constrained IoT sensor nodes and portable medical devices. |
| Separately controlled SPST switches | Four independent channels with distinct logic polarity - allows simultaneous configuration of NO/NC pairs for flexible signal path reconfiguration. |
| Pin compatibility with DG211/DG212/DG213 | Direct PCB replacement in legacy designs - eliminates layout changes when upgrading to lower leakage and improved RON flatness. |
| Charge injection <5pC | Minimizes voltage glitch on sampled capacitors - critical for high-resolution SAR ADC multiplexers and precision instrumentation front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522ESE | Four NO-only channels; identical RON, leakage, and timing specs; same pinout. | Suitable where all four paths require active-high enable (e.g., uniform sensor array scanning). | Select MAX4522ESE when full NO functionality is required and NC behavior is unnecessary. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, but higher 25nA max off-leakage at +85°C; 16-TSSOP package. | Better RON for low-gain precision circuits, but less suitable for ultra-low-power battery hold modes. | Choose ADG1412BRUZ only if sub-2Ω RON outweighs 25× higher leakage versus MAX4523ESE's 10nA at +85°C. |
Compared with MAX4522ESE (NO-only) and ADG1412BRUZ (lower RON, higher leakage), the MAX4523ESE uniquely balances mixed NO/NC topology, ultra-low leakage, and proven pin compatibility - making it optimal for fault-tolerant, low-power, and legacy-replacement designs.

FAQ
What supply configurations does the MAX4523ESE support?
The MAX4523ESE operates with dual supplies from ±2V to ±6V or a single supply from +2V to +12V. When using single supply, V− must be tied to GND. It is fully specified for +2.7V single-supply operation, supporting Li-ion battery-powered systems without level-shifting circuitry. All logic thresholds remain TTL/CMOS-compatible across this range.
How does the mixed NO/NC configuration of the MAX4523ESE differ from MAX4521ESE and MAX4522ESE?
The MAX4523ESE integrates two NO switches (controlled by IN1/IN4) and two NC switches (controlled by IN2/IN3), enabling fail-safe or default-path routing. In contrast, MAX4521ESE has four NC-only channels, and MAX4522ESE has four NO-only channels. This hybrid topology makes MAX4523ESE ideal for redundancy switching or power-up default signal paths without external pull resistors.
What is the maximum allowable voltage difference between V+ and V− for the MAX4523ESE?
The absolute maximum V+ to V− differential is 13.0V. While the device supports ±6V nominal supplies, system design must ensure worst-case tolerances (e.g., ±10% on ±6V yields 13.2V) and transient spikes do not exceed this limit. Exceeding 13.0V risks permanent damage, even briefly - derating to ≤12.5V is recommended for robust designs.
Can the MAX4523ESE handle bipolar analog signals when powered from a single +5V supply?
No. With V− tied to GND in single-supply mode, the analog signal range is limited to 0V to V+ (0V to +5V). Bipolar signals (e.g., ±2.5V) require dual-supply operation (e.g., V+ = +5V, V− = −5V) to enable rail-to-rail swing from −5V to +5V. Attempting bipolar signals on single supply will forward-bias internal ESD diodes and cause distortion or damage.
Is the MAX4523ESE pin-compatible with industry-standard analog switches?
Yes. The MAX4523ESE shares identical pinout and footprint with DG211, DG212, and DG213 - including pin assignments for INx, COMx, NOx/NCx, V+, V−, GND, and N.C. This allows drop-in replacement in existing layouts, delivering improved on-resistance matching (4Ω vs. 10Ω typical), lower leakage, and enhanced ESD protection without PCB revision.
