Product details
Overview
MAX4502CPA from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), low-voltage CMOS analog switch operating from +2V to +12V single supply. It supports rail-to-rail analog signal switching, delivers 250Ω on-resistance at +5V, exhibits 1nA off-leakage at +25°C, and features TTL/CMOS-compatible logic thresholds-used in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4502CPA datasheet, MAX4502CPA pinout, MAX4502CPA application, or MAX4502CPA equivalent, key selection criteria include guaranteed on-resistance over temperature, ultra-low leakage performance across voltage and temperature ranges, fast 75ns turn-on time, and compatibility with +5V logic control in portable and space-constrained designs.
Technical Context
The MAX4502CPA implements a fully complementary CMOS transmission-gate architecture with internal logic-level translation, enabling direct interface to +5V TTL/CMOS inputs while supporting analog signals from GND to V+. Its NC configuration means the COM–NC path remains conductive when IN is low, and opens when IN is high-enabling fail-safe signal continuity in power-loss scenarios.
All analog terminals (COM, NC, NO) feature bidirectional ESD protection diodes to V+ and GND, defining absolute maximum ratings and contributing to leakage behavior. The device draws no static current from V+ except for ESD-diode reverse leakage and input logic current-resulting in sub-µA quiescent supply current under static conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply-supports direct integration into 3.3V, 5V, and 9V battery or regulator-based systems without level-shifting. |
| On-Resistance (RON) | 250Ω max at +5V, TA = +25°C-ensures minimal signal attenuation and distortion in precision low-level analog paths. |
| Off-Leakage Current | 1nA max at +25°C, 10nA max at +85°C-preserves accuracy in high-impedance sensor front-ends and sample-hold circuits. |
| Switching Speed | tON = 75ns, tOFF = 50ns (RL = 1kΩ, CL = 35pF)-enables reliable multiplexing in medium-speed data acquisition up to ~1MHz. |
| Charge Injection | 10pC typical-limits voltage glitch on sampled nodes, critical for ADC input settling and precision integrator applications. |
| Logic Compatibility | VINH = 2.4V, VINL = 0.8V at +5V supply-guarantees robust interfacing with standard 5V microcontrollers and logic families. |
| Analog Signal Range | Rail-to-rail (GND to V+)-allows full utilization of supply headroom for unipolar or bipolar signal routing with no clipping. |
Pinout & Package
MAX4502CPA is housed in an 8-pin plastic DIP package (0.300" wide), compatible with through-hole prototyping and industrial PCB assembly. Pin assignments are identical to the SO package variant but with larger pitch and lead form for manual soldering and socket use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive supply rail | Supplies both analog switch core and digital control circuitry; sets upper analog signal limit and logic threshold reference. |
| 2 - COM | Analog common terminal | Bidirectional node connecting to NC when IN = low; serves as central signal hub for SPST NC switching path. |
| 3 - N.C. | No internal connection | Unbonded pin-must be left floating or tied to GND per layout best practice; no electrical function or parasitic impact. |
| 4 - V+ | Positive supply rail (duplicate) | Second V+ connection for improved supply decoupling and reduced IR drop in high-current or noise-sensitive layouts. |
| 5 - NC | Analog normally-closed terminal | Completes NC path with COM when IN = low; interchangeable with NO/COM per datasheet-bidirectional signal routing. |
| 6 - GND | Ground reference | Return path for logic and analog sections; must be low-impedance to minimize crosstalk and ensure stable threshold behavior. |
| 7 - IN | Digital control input | Active-high logic input controlling NC path state; 0.8V/2.4V thresholds ensure noise margin with 5V CMOS/TTL drivers. |
| 8 - N.C. | No internal connection | Unbonded pin-no internal bond wire; electrically inert and should not be connected to any net. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Enables full-swing signal handling from GND to V+, eliminating clipping in unipolar sensor or audio paths. |
| Guaranteed 250Ω on-resistance | Ensures predictable channel gain error and THD in precision instrumentation, independent of production lot or temperature drift. |
| 1nA max off-leakage at +25°C | Preserves DC accuracy in high-Z circuits such as photodiode transimpedance amplifiers or electrometer-grade measurement nodes. |
| 75ns turn-on / 50ns turn-off | Supports multiplexed sampling at >1MHz rates with minimal aperture uncertainty in data-acquisition front-ends. |
| TTL/CMOS logic compatibility | Eliminates need for external level shifters when driven by standard 5V microcontrollers, FPGAs, or logic ICs. |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ | ±15V dual-supply operation; 0.9Ω RON; 1.5nA leakage at +25°C; 10-lead MSOP package. | Requires dual rails and offers lower RON but higher cost; suited for high-precision lab equipment-not battery-operated. | Select when ultra-low on-resistance and dual-supply flexibility outweigh size and power constraints. |
| TS5A23157DGSR | +1.65V to +5.5V supply; 0.9Ω RON at 3.3V; 10nA leakage at +25°C; 10-pin VSSOP; no 12V rating. | Optimized for 3.3V systems only; lacks 12V tolerance and rail-to-rail swing above 3.3V-unsuitable for 9V/12V battery apps. | Prefer for compact 3.3V embedded designs where MAX4502CPA's 12V range is unnecessary. |
Compared with ADG1419BRMZ and TS5A23157DGSR, the MAX4502CPA uniquely balances wide single-supply operation (+2V to +12V), NC default state, and DIP package for serviceability-making it optimal for industrial, telecom, and legacy hardware where voltage flexibility and mechanical robustness are prioritized over ultra-low RON.

FAQ
What is the operating temperature range for the MAX4502CPA?
The MAX4502CPA is rated for 0°C to +70°C ambient operation, as indicated by the 'C' grade suffix in its part number. This commercial-grade temperature range suits indoor consumer electronics, office equipment, and non-automotive industrial controls. It does not support extended or military temperature grades-those require MAX4502EPA (–40°C to +85°C) or MAX4502MJA (–55°C to +125°C) variants.
Does the MAX4502CPA support rail-to-rail analog signals?
Yes, the MAX4502CPA supports rail-to-rail analog signal operation from GND to V+, meaning it can pass signals spanning the full supply range without clipping. This capability is confirmed in the datasheet's Absolute Maximum Ratings and Electrical Characteristics tables, and applies across its entire +2V to +12V supply range-critical for preserving dynamic range in audio and sensor interfaces.
What is the maximum supply voltage the MAX4502CPA can tolerate?
The MAX4502CPA has an absolute maximum V+ rating of +13V, but its specified operational range is +2V to +12V. Operation at +12V is fully characterized: on-resistance drops to 200Ω, off-isolation remains >–100dB at 100kHz, and leakage stays within 50nA at +85°C. Exceeding +13V risks permanent damage due to internal ESD diode breakdown.
Is the MAX4502CPA pin-compatible with the MAX4501CPA?
No-the MAX4502CPA and MAX4501CPA share identical pinouts and packages, but differ in functional state: MAX4502CPA is normally closed (NC), while MAX4501CPA is normally open (NO). Swapping them without logic inversion will invert system behavior (e.g., default signal path becomes disconnected). They are functionally complementary-not drop-in replacements.
What package type is used for the MAX4502CPA?
The MAX4502CPA uses an 8-pin plastic DIP (dual in-line package) with 0.300" body width and standard 0.1" pin pitch. This through-hole package supports breadboarding, socket-based testing, and legacy PCB assembly-distinct from the SOT23-5 or SO variants denoted by suffixes like 'CUK-T' or 'CSA'.
