Product details
Overview
MAX4502ESA 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, and exhibits only 10nA off-leakage at +85°C-ideal for precision low-power signal routing in battery-operated audio and data-acquisition systems.
For engineers reviewing the MAX4502ESA datasheet, MAX4502ESA pinout, MAX4502ESA application, or MAX4502ESA equivalent, this page provides verified package mapping (8-pin SO), confirmed NC switching behavior, guaranteed dynamic specs (tON = 75ns, tOFF = 50ns), leakage performance across temperature, and TTL/CMOS-compatible logic thresholds at +5V supply.
Technical Context
The MAX4502ESA implements a fully complementary CMOS transmission gate architecture with internal level-shifting logic, enabling direct interface to +5V TTL/CMOS inputs while driving analog paths up to V+ rail. Its NC configuration ensures default conduction path between COM and NC terminals until deasserted by logic-high IN.
All analog terminals (COM, NC, NO) feature bidirectional ESD protection diodes to V+ and GND, defining absolute maximum analog voltage range as –0.3V to (V+ + 0.3V). Leakage current is dominated by reverse-biased ESD diode mismatch, resulting in temperature-dependent off-leakage (1nA @ +25°C, 10nA @ +85°C) and on-leakage (2nA @ +25°C, 20nA @ +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - conducts by default; breaks path when IN = HIGH |
| Supply Range | +2V to +12V single supply - enables operation from Li-ion battery (3.0–4.2V) up to industrial 12V rails |
| On-Resistance | 250Ω max at V+ = +5V, TA = –40°C to +85°C - ensures minimal signal attenuation in low-current sensor/data paths |
| Off-Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance measurement circuits (e.g., pH sensors, thermocouples) |
| Switching Speed | tON = 75ns, tOFF = 50ns (RL = 1kΩ, CL = 35pF) - supports multiplexing of audio and medium-speed data signals |
| Logic Compatibility | VINH = 2.4V min, VINL = 0.8V max at V+ = +5V - interoperable with standard 5V microcontrollers and logic families |
| Charge Injection | 10pC max - limits voltage glitch on sampled-hold nodes and prevents settling errors in ADC front-ends |
Pinout & Package
MAX4502ESA uses an 8-pin SO (Small Outline) package with exposed pad not connected internally. Pin functions are electrically identical to the SO/DIP variant shown in the datasheet Figure 1 and Pin Description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply for analog and digital circuitry; sets analog signal rail limits and powers internal logic translators |
| 2 | GND | Analog/digital ground reference; return path for ESD diode leakage and logic currents |
| 3 | IN | Digital control input; HIGH disables NC path (opens switch), LOW enables conduction |
| 4 | N.C. | No internal connection - must be left floating or tied to GND/V+ per layout best practice (no electrical function) |
| 5 | NC | Normally closed analog terminal - permanently connected to COM when IN = LOW |
| 6 | N.C. | No internal connection - unused pin; no bonding wire or die connection |
| 7 | NO | Normally open analog terminal - unconnected to COM unless used in MAX4501 variant; electrically isolated in MAX4502ESA |
| 8 | COM | Common analog terminal - bidirectional signal path shared with NC (or NO in MAX4501); supports rail-to-rail voltage swing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V+ to GND voltage range on COM/NC - eliminates level-shifting in single-supply sensor interfaces |
| Low charge injection (10pC) | Minimizes voltage step error on capacitive nodes - critical for sample-and-hold and switched-capacitor filter stability |
| Guaranteed 250Ω on-resistance | Ensures predictable channel gain and THD in audio routing - avoids calibration drift across temperature (-40°C to +85°C) |
| TTL/CMOS-compatible logic thresholds | Eliminates need for external level shifters when driven by 5V microcontrollers or FPGAs |
| 10nA max off-leakage at +85°C | Preserves DC accuracy in high-impedance medical and instrumentation front-ends without active guarding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRZ | 4-channel, +5V-only supply, 1.8Ω on-resistance, but requires dual supply or level shifter for 2–12V operation | Higher channel count and lower RON, but incompatible with single-supply battery systems below 4.5V | Select ADG1412BRZ only when multi-channel integration and sub-2Ω RON outweigh supply flexibility needs. |
| TS5A23157DGSR | Single-supply 1.65–5.5V, 0.9Ω RON, but rated only to +85°C and lacks guaranteed 10nA off-leakage spec | Better RON and smaller SC70-6 package, but insufficient leakage performance for precision >85°C industrial sensing | Choose TS5A23157DGSR for cost-sensitive consumer audio where leakage >100nA is acceptable above +70°C. |
Compared with ADG1412BRZ and TS5A23157DGSR, the MAX4502ESA uniquely balances wide 2–12V single-supply operation, guaranteed low leakage across its full –40°C to +85°C range, and NC fail-safe behavior-making it irreplaceable in battery-powered instrumentation requiring default-conductive signal paths and thermal stability.

FAQ
What is the default switching state of the MAX4502ESA?
The MAX4502ESA is a normally closed (NC) analog switch: when the IN pin is logic LOW (≤0.8V), the COM and NC terminals are conductive. When IN is logic HIGH (≥2.4V at +5V supply), the path opens. This NC behavior is intrinsic to the MAX4502ESA silicon design and cannot be altered by external configuration. The MAX4502ESA maintains this state across its full –40°C to +85°C operating range.
Does the MAX4502ESA support rail-to-rail analog signals?
Yes, the MAX4502ESA supports rail-to-rail analog signal operation: analog voltages on COM and NC can swing from GND to V+ without distortion or clipping. This is enabled by its CMOS transmission-gate architecture and internal charge-pump-free design. The MAX4502ESA achieves this across its entire +2V to +12V supply range, making it suitable for direct interfacing with sensors and DACs operating at varying supply rails.
What is the maximum off-leakage current specification for the MAX4502ESA at +85°C?
The MAX4502ESA guarantees a maximum off-leakage current of 10nA at +85°C, as specified in the Electrical Characteristics table for the E-grade (–40°C to +85°C) version. This value applies to both NC-to-COM and COM-to-NC paths when the switch is open (IN = HIGH). The MAX4502ESA's leakage is 100% production tested at maximum-rated temperature and correlated to +25°C performance per datasheet Note 3.
Can the MAX4502ESA operate from a +3V supply while accepting standard TTL logic inputs?
No-the MAX4502ESA must not be operated from +3V while receiving TTL-level inputs. At V+ = +3V, the absolute maximum rating for any digital input is V+ + 0.3V = +3.3V, but standard TTL outputs can exceed +3.3V (up to +3.6V), risking permanent damage. The MAX4502ESA's logic thresholds scale with V+; for reliable TTL compatibility, V+ must be ≥+4.5V. The MAX4502ESA datasheet explicitly warns against this condition in the Applications Information section.
What package type does the MAX4502ESA use, and are all pins functional?
The MAX4502ESA uses an 8-pin SO (Small Outline) package with pins 1 (V+), 2 (GND), 3 (IN), 5 (NC), and 8 (COM) being functional. Pins 4 and 6 are labeled N.C. (No Connection) and have no internal bond wire or die connection-they must remain unconnected. Pin 7 is the NO terminal, which is electrically isolated in the MAX4502ESA (as opposed to the MAX4501ESA). This pinout matches the SO/DIP variant shown in the MAX4502ESA datasheet Figure 1.
