Product details
Overview
MAX4501ESA from Maxim Integrated is a single-pole/single-throw (SPST), normally open (NO), 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 front-ends.
For engineers reviewing the MAX4501ESA datasheet, MAX4501ESA pinout, MAX4501ESA application, or MAX4501ESA equivalent, key selection criteria include guaranteed on-resistance over temperature, leakage performance at extended industrial temperature range (−40°C to +85°C), SO-8 package compatibility with legacy layouts, and rail-to-rail signal handling without level-shifting circuitry.
Technical Context
The MAX4501ESA implements a CMOS transmission-gate architecture with dual ESD diodes per analog terminal (to V+ and GND), enabling rail-to-rail signal operation while defining analog voltage limits strictly by the V+ and GND supply rails. Its digital control interface uses internally translated logic thresholds that scale with supply voltage - 0.8V/2.4V at +5V, ~3V high threshold at +12V - ensuring robust compatibility across mixed-supply systems.
Switching dynamics are governed by charge injection (10pC typical), turn-on time of 75ns, and turn-off time of 50ns under +5V/1kΩ/35pF load conditions. Off-isolation exceeds −100dB at 100kHz, degrading predictably with frequency due to capacitive coupling, not resistive leakage paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery or industrial systems without auxiliary regulators. |
| On-Resistance (RON) | 250Ω max at +5V, TA = −40°C to +85°C - ensures minimal signal attenuation and gain error in precision sensor or audio signal paths. |
| Off-Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance measurement nodes (e.g., pH sensors, thermocouple amplifiers). |
| Charge Injection | 10pC typical - limits voltage glitch on sampled-hold capacitors, critical for ADC front-end multiplexing. |
| Logic Compatibility | 0.8V/2.4V thresholds at +5V - directly interfaces with standard TTL and CMOS outputs without level shifters. |
| Switching Speed | tON = 75ns, tOFF = 50ns - supports multiplexing of audio-band and medium-speed serial signals (e.g., RS-232 control lines). |
| Rail-to-Rail Operation | Analog signal range = GND to V+ - eliminates clipping when switching full-scale signals in unipolar systems. |
Pinout & Package
MAX4501ESA is housed in an 8-pin SO (Small Outline) package with standard 1.27mm pitch, compatible with IPC-7351B SOIC-8 land patterns. Pin 1 is V+, pin 2 is COM, pin 3 is NO, pin 4 is NC (not internally connected), pin 5 is GND, pin 6 is IN, pin 7 and pin 8 are N.C. (no internal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail for analog and digital circuitry | Powers internal CMOS switches and logic translators; sets upper analog signal limit; must be decoupled locally. |
| COM | Analog common terminal | Central node for bidirectional signal routing; connects to either NO or NC depending on IN state. |
| NO | Normally open analog terminal | Open-circuit path when IN = LOW; closes to COM when IN = HIGH - provides default isolation in fail-safe designs. |
| NC | No connection (not internally connected) | Unused pin; must remain floating or grounded per layout best practices - no internal silicon connection. |
| GND | Ground reference for analog and digital domains | Common return for supply current and logic thresholds; requires low-impedance connection to minimize noise coupling. |
| IN | Digital control input | Active-HIGH logic input; drives internal gate drivers; compatible with 0.8V/2.4V thresholds at +5V supply. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance | 250Ω max at +5V across −40°C to +85°C - ensures predictable channel loss in production environments without derating. |
| Low off-leakage | 10nA max at +85°C - maintains integrity of high-Z sensor inputs and sample-and-hold circuits over full temperature range. |
| Fast switching | 75ns turn-on / 50ns turn-off - enables time-division multiplexing of multiple analog channels at >1MHz effective rate. |
| Rail-to-rail signal handling | GND to V+ analog range - eliminates need for external biasing or clamping in unipolar signal chains. |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V - allows direct interfacing with microcontroller GPIOs and FPGA I/O banks without level translation. |

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 | Higher supply range (+5V to ±15V), lower RON (0.6Ω), but requires dual supply or charge pump; SO-8 package. | Designed for precision instrumentation requiring ultra-low on-resistance and distortion; not suitable for single-supply ≤+3.3V systems. | Select ADG1419BRMZ only when sub-1Ω RON and <0.001% THD are mandatory - not a drop-in replacement for MAX4501ESA. |
| TS5A23157DGSR | Lower voltage range (+1.65V to +5.5V), smaller SC70-6 package, 0.9Ω RON at +3.3V, but rated only to +85°C and lacks rail-to-rail support above +3.6V. | Optimized for space-constrained mobile applications with 3.3V logic; cannot replace MAX4501ESA in +9V/+12V or rail-to-rail >+3.6V use cases. | Choose TS5A23157DGSR for compact 3.3V-only designs where size outweighs voltage flexibility - not functionally equivalent at full MAX4501ESA spec range. |
Compared with ADG1419BRMZ and TS5A23157DGSR, the MAX4501ESA uniquely balances wide single-supply operation (+2V to +12V), guaranteed rail-to-rail analog range, industrial temperature rating, and SO-8 footprint - making it irreplaceable in mixed-voltage, battery-backed, or legacy-compatible analog routing systems.

FAQ
What is the maximum supply voltage rating for the MAX4501ESA?
The MAX4501ESA has an absolute maximum V+ rating of +13V, with continuous operation specified from +2V to +12V. Exceeding +13V risks permanent damage due to internal ESD diode breakdown. For reliable long-term operation, design margins should keep V+ ≤ +12V, especially at elevated temperatures where leakage increases.
Does the MAX4501ESA support bidirectional analog signal flow?
Yes, the MAX4501ESA supports fully bidirectional signal flow between COM and NO terminals. Its CMOS transmission-gate structure imposes no directionality - signals pass equally well from COM to NO or NO to COM, provided voltage levels remain within GND to V+. This enables flexible use in both source and load positions within analog signal chains.
What is the guaranteed on-resistance specification for MAX4501ESA over its full operating temperature range?
The MAX4501ESA guarantees on-resistance ≤250Ω at +5V supply across its full operating temperature range of −40°C to +85°C. At +25°C, typical RON is 160Ω. This specification is production-tested and applies to COM–NO conduction; resistance remains stable and monotonic versus VCOM up to V+.
Can the MAX4501ESA be used with a +3.3V supply and standard 3.3V logic inputs?
Yes, the MAX4501ESA operates down to +2V supply and accepts logic inputs compatible with 3.3V CMOS levels. At +3.3V supply, the logic thresholds scale to approximately 0.7V (low) and 2.1V (high), remaining safely within 3.3V logic swing. However, on-resistance increases to ~600Ω, and off-leakage rises - verify system-level signal integrity at target operating point.
Is the NC pin on the MAX4501ESA required to be left floating or can it be tied to ground?
The NC pin (pin 4 in SO-8) is not internally connected and must be left floating per Maxim's datasheet guidance. Tying it to ground or V+ introduces no functional benefit and may increase parasitic capacitance or risk unintended coupling in high-frequency layouts. Standard practice is to omit solder paste or leave the pad unconnected in PCB design.
