Product details
Overview
MAX324ESA+G002 from Maxim Integrated is a precision dual SPST analog switch with normally closed (NC) configuration, designed for single-supply operation from +2.7V to +16V. It delivers 60Ω max on-resistance, <2Ω channel matching, and <100ns turn-off time, enabling high-fidelity signal routing in battery-powered instrumentation and precision sample-and-hold circuits.
For engineers reviewing the MAX324ESA+G002 datasheet, MAX324ESA+G002 pinout, MAX324ESA+G002 application, or MAX324ESA+G002 equivalent, key selection criteria include guaranteed NC switching behavior, 100pA max off-leakage at +85°C, 5pC max charge injection, and SO-8 package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The MAX324ESA+G002 implements two independent normally closed analog switches using CMOS transmission-gate architecture, with rail-to-rail analog signal handling (0V to V+) and TTL/CMOS-compatible logic inputs. Its internal structure ensures break-before-make is not implemented-unlike the MAX325-making it suitable for applications requiring simultaneous conduction paths during state transitions.
It operates without dual-supply biasing and maintains low RON flatness (<6Ω) across the full analog voltage range under +5V supply, while leakage remains below 2.5nA at +85°C. Charge injection is tightly controlled at ≤5pC, critical for minimizing glitch-induced errors in high-resolution ADC/DAC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPST, normally closed (NC) - both channels conduct when logic input is low |
| Supply Voltage Range | +2.7V to +16V single supply - eliminates need for negative rail in portable systems |
| Max On-Resistance | 60Ω at +5V - ensures minimal signal attenuation and gain error in precision signal paths |
| RON Matching | <2Ω between channels - enables matched gain/attenuation in differential or dual-path circuits |
| Charge Injection | ≤5pC - limits voltage step error in sample-and-hold and multiplexed ADC front-ends |
| Off-Leakage Current | ≤100pA at +25°C, ≤2.5nA at +85°C - preserves accuracy in high-impedance sensor interfaces |
| Switching Speed | tON ≤150ns, tOFF ≤100ns - supports >5MHz multiplexing in real-time data acquisition |
Pinout & Package
MAX324ESA+G002 is housed in an 8-pin SO (Small Outline) package, 150-mil body width, with standard JEDEC MS-012AC footprint and moisture sensitivity level MSL-1. Pin 1 is marked with a beveled corner or dot; device orientation follows standard SO top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts +2.7V to +16V; powers internal logic and switch transistors; must be applied before analog/logic signals |
| IN1, IN2 | Logic control inputs | TTL/CMOS-compatible; low = NC path closed, high = NC path open; no internal pull-ups |
| COM1, COM2 | Analog common terminals | Bidirectional current paths; connect to signal source or load depending on system topology |
| NC1, NC2 | Normally closed analog switch terminals | Conduct to respective COM pins when INx = low; open when INx = high; no NO functionality |
| V− | Ground reference | Return path for supply and logic; must be tied to system GND; not a negative supply pin |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe conduction path in power-loss or logic-reset conditions for safety-critical monitoring |
| Single-supply operation | Eliminates dual-rail generation circuitry, reducing BOM count and PCB area in portable medical and test equipment |
| Guaranteed low charge injection | ≤5pC enables sub-12-bit accuracy retention in switched-capacitor circuits without calibration overhead |
| High ESD robustness | ≥2000V per Method 3015.7 allows direct handling in non-EPA environments during prototyping and repair |
| Low power consumption | <5µW quiescent supply current extends battery life in always-on sensor nodes and remote telemetry units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX324CSA | Same silicon, 0°C to +70°C temperature range, SO-8 package | Not qualified for industrial (-40°C to +85°C) operation; unsuitable for automotive or outdoor deployments | Select MAX324CSA only for commercial-grade consumer electronics with ambient temperature control. |
| ADG1419BRMZ | Single-supply compatible but requires ≥±5V dual supply for full spec compliance; 4.5Ω typical RON, higher 12pC charge injection | Higher performance in on-resistance but compromises in charge injection and leakage stability over temperature | Choose ADG1419BRMZ only when ultra-low RON dominates design priority and thermal drift can be calibrated out. |
Compared with MAX324ESA+G002, MAX324CSA offers identical electrical behavior but lacks extended temperature qualification, while ADG1419BRMZ trades lower on-resistance for higher charge injection and reduced leakage stability-making MAX324ESA+G002 optimal for uncalibrated, wide-temperature, low-glitch precision signal routing.

FAQ
What is the maximum allowable supply voltage for MAX324ESA+G002?
The absolute maximum supply voltage for MAX324ESA+G002 is +17V referenced to V−, though operational specification guarantees performance only up to +16V. Exceeding +17V risks permanent damage due to internal junction breakdown, and derating is recommended above +12V for long-term reliability in high-temperature environments. Always observe the 10% tolerance window around nominal V+ in dynamic operation.
Does MAX324ESA+G002 support rail-to-rail analog signal switching?
Yes, MAX324ESA+G002 supports rail-to-rail analog signal switching from 0V to V+, with guaranteed on-resistance flatness (<6Ω) and minimal distortion across the full range. This capability is validated at +5V, +3.3V, and +12V supplies, and applies equally to COM, NC1, and NC2 terminals-enabling direct interfacing with DAC outputs and op-amp rails without level-shifting.
Is MAX324ESA+G002 pin-compatible with MAX323ESA+ or MAX325ESA+?
No, MAX324ESA+G002 is not pin-compatible with MAX323ESA+ or MAX325ESA+. While all three share the same SO-8 package and pin numbering, their terminal functions differ: MAX323 uses NO1/NO2, MAX324 uses NC1/NC2, and MAX325 uses NO1/NC2. Swapping them without board revision will result in inverted or non-functional switching behavior.
What is the guaranteed leakage current specification for MAX324ESA+G002 at +85°C?
MAX324ESA+G002 guarantees NC and COM off-leakage current ≤2.5nA at +85°C, measured per datasheet condition (V+ = 5.5V, VCOM = 4.5V, VNC = 1V). This value is 100% tested at hot temperature and correlated to room-temperature screening, ensuring predictable performance in thermally stressed industrial enclosures and avionics bays.
Can MAX324ESA+G002 be used with a 3.3V logic interface while powered from +5V?
Yes, MAX324ESA+G002 accepts 3.3V logic levels on IN1/IN2 when V+ = +5V, as its logic thresholds (VINL ≤ 0.8V, VINH ≥ 2.4V) are fully satisfied. However, ensure the 3.3V driver has sufficient drive strength to overcome input capacitance (≈10pF), and avoid floating inputs-unconnected logic pins must be tied to V+ or V− to prevent undefined switching states in MAX324ESA+G002.
