Product details
Overview
MAX4648EUT from Maxim Integrated is a single-pole/single-throw (SPST) normally open analog switch in SOT23-6 package, operating from dual ±4.5V to ±20V or single +9V to +36V supplies. It delivers 25Ω max on-resistance, 2Ω max on-resistance flatness, 1nA max off-leakage at +25°C, and supports rail-to-rail analog signal switching in telecom and test equipment signal routing.
For engineers reviewing the MAX4648EUT datasheet, MAX4648EUT pinout, MAX4648EUT application, or MAX4648EUT equivalent, key selection criteria include guaranteed RON flatness over full signal range, ±15V dual-supply compatibility, sub-100ns switching times, low charge injection (4pC), and SOT23-6 footprint suitability for space-constrained analog routing designs.
Technical Context
The MAX4648EUT implements a CMOS-based SPST switch with complementary transistor pairs enabling bidirectional signal conduction and rail-to-rail operation. Its control logic accepts standard TTL/CMOS levels (VIH = 2.4V, VIL = 0.8V) without requiring a separate VL supply.
It features internal ESD protection and operates across -40°C to +85°C with guaranteed performance via design correlation - not full-temperature testing - as confirmed by SOT23-6 100% +25°C functional screening per datasheet Note 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 25Ω max (±15V supplies); ensures minimal signal attenuation and voltage drop in precision analog paths. |

| Off-Leakage Current | 1nA max at +25°C; preserves high-impedance node integrity in sample-and-hold or sensor interfaces. |
| Switching Speed | tON/tOFF = 100ns typ (±15V); enables fast multiplexing in automated test equipment and data acquisition systems. |
| Charge Injection | 4pC typ; minimizes voltage glitch on high-impedance COM nodes during switching transitions. |
| Analog Signal Range | Rail-to-rail (V− to V+); supports full dynamic range of bipolar or unipolar signals without clipping. |

Pinout & Package
SOT23-6 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO (Normally Open) | Analog switch terminal disconnected from COM when IN = low; connects only upon logic high enable. |
| 2 | V− | Negative supply rail input; must be connected for dual-supply operation or grounded for single-supply use. |
| 3 | IN | Digital control input; TTL/CMOS-compatible, no VL supply required, active-high logic sense. |
| 4 | GND | Ground reference for logic and substrate; ties to system ground plane for noise immunity. |
| 5 | V+ | Positive supply rail input; supports up to +36V in single-supply mode or +20V in dual-supply mode. |
| 6 | COM | Common analog port; bidirectional signal path shared between NO and internal switch element. |

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 | 2.5Ω typical RON, ±15V supply, but requires VL supply for logic interface. | Higher precision, lower RON, but adds complexity in single-rail logic environments. | Select ADG1419BRMZ where ultra-low on-resistance and tighter flatness are critical and VL rail is available. |
| TS5A23157DCKR | 0.9Ω typical RON, +1.65V to +5.5V supply only; no dual-supply support. | Optimized for low-voltage portable audio, not suitable for ±15V or high-voltage industrial routing. | Choose TS5A23157DCKR for battery-powered consumer audio where supply headroom is limited to 5V. |
Compared with ADG1419BRMZ and TS5A23157DCKR, the MAX4648EUT uniquely balances wide supply flexibility (±4.5V to ±20V or +9V to +36V), no-VL logic interface, and robust leakage performance - making it optimal for industrial and telecom signal routing where supply architecture varies and layout simplicity matters.

FAQ
What is the maximum supply voltage rating for MAX4648EUT?
The MAX4648EUT supports dual supplies up to ±20V (V+ to V− ≤ 44V) or single supply up to +36V. Absolute maximum ratings specify V+ ≤ +44.0V, V− ≥ −44.0V, and V+ to V− ≤ +44.0V. Exceeding these limits risks permanent damage, per datasheet Absolute Maximum Ratings table.
Does MAX4648EUT require a separate logic supply voltage (VL)?
No, the MAX4648EUT does not require a separate VL supply. Its digital input (IN) accepts standard TTL/CMOS logic levels (VIH = 2.4V min, VIL = 0.8V max) referenced to GND, regardless of V+ or V− voltage. This eliminates the need for an auxiliary logic rail and simplifies system power design.
What is the on-resistance flatness specification for MAX4648EUT and why does it matter?
The MAX4648EUT guarantees on-resistance flatness of 2Ω max over its specified analog signal range (V− to V+). Flatness is defined as the difference between max and min RON across that range. This tight tolerance ensures consistent gain, minimal harmonic distortion, and predictable settling behavior - critical in audio, instrumentation, and precision multiplexing applications.
Can MAX4648EUT operate from a single 12V supply?
Yes, the MAX4648EUT is fully specified for single-supply operation from +9V to +36V. At +12V, typical on-resistance is 4Ω with 6Ω max flatness, tON/tOFF is 100ns/150ns, and off-leakage remains ≤10nA across temperature. The device maintains rail-to-rail signal handling (0V to +12V) in this configuration.
What is the thermal performance of MAX4648EUT in SOT23-6 package?
In the SOT23-6 package, the MAX4648EUT has a continuous power dissipation of 696mW at TA = +70°C, derating 8.7mW/°C above that temperature. Junction temperature must not exceed +150°C. Thermal resistance θJA is approximately 115°C/W, meaning under 100mW power dissipation at +70°C ambient, junction temperature rises ~11.5°C - well within safe operating limits.
