Product details
Overview
MAX4622EPE+ from Maxim Integrated is a precision dual SPDT analog switch with two normally closed (NC) and two normally open (NO) poles, 5Ω max on-resistance, guaranteed 0.5Ω max channel-to-channel RON match, and break-before-make operation. It operates from single (+4.5V to +36V) or bipolar (±4.5V to ±18V) supplies and supports rail-to-rail analog signal switching up to ±15V - ideal for audio-signal routing and test equipment where low distortion and tight matching are critical.
For engineers reviewing the MAX4622EPE+ datasheet, MAX4622EPE+ pinout, MAX4622EPE+ application, or MAX4622EPE+ equivalent, key selection criteria include guaranteed break-before-make timing, sub-200ns turn-off time, <5nA off-leakage at +85°C, and compatibility with TTL/CMOS logic levels across wide supply ranges - all validated for industrial temperature operation (-40°C to +85°C).
Technical Context
The MAX4622EPE+ implements monolithic CMOS analog switch architecture with integrated protection diodes and logic-level translation via VL pin. Its dual SPDT topology provides independent control of two switch pairs, each with strict break-before-make timing (tD = 90–200ns typ) to prevent signal shorting during state transitions.
It maintains flat on-resistance (∆RON ≤ 0.5Ω max over full signal range) and ultra-low charge injection (45pC typ), enabling high-fidelity signal routing in data-acquisition systems and communication front-ends where signal integrity and settling accuracy are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 5Ω max - ensures minimal voltage drop and power loss when routing ±10V analog signals at 10mA load. |
| RON match | 0.5Ω max - guarantees matched gain/attenuation in differential or dual-path signal chains without calibration. |
| Turn-off time | <200ns - enables fast channel switching in automated test equipment with ≥5MHz update rates. |
| Off-leakage (85°C) | <5nA - preserves DC accuracy in high-impedance sensor interfaces and precision integrators. |
| Supply range | +4.5V to +36V (single) or ±4.5V to ±18V (bipolar) - supports legacy industrial rails and modern low-voltage systems without level-shifting. |
| Rail-to-rail analog | VCOM = V+ to V− - allows full-swing signal handling across entire supply range without clipping. |
| Logic compatibility | TTL/CMOS - accepts standard 0.8V/2.4V thresholds with <0.5µA input current, simplifying microcontroller interface. |
Pinout & Package
MAX4622EPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin pitch is 0.1 inch; lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Digital logic inputs (IN1, IN2) | Active-high control lines; drive internal switches with TTL/CMOS-compatible thresholds. |
| 2, 7 | Switch common terminals (COM1, COM2) | Analog signal path inputs; connect to source signals requiring routing to NO/NC paths. |
| 3, 6, 8, 16 | Normally open terminals (NO1, NO2, NO3, NO4) | Open-circuit by default; close to COMx only when corresponding INx = high. |
| 4, 5, 9, 15 | Normally closed terminals (NC1, NC2, NC3, NC4) | Shorted to COMx by default; open only when corresponding INx = high (break-before-make enforced). |
| 12 | Positive supply (V+) | Primary analog supply rail; supports up to +36V in single-supply mode or +18V in bipolar mode. |
| 14 | Negative supply (V−) | Required for bipolar operation; accepts down to −18V; clamped internally to prevent latch-up. |
| 13 | Logic supply (VL) | Separate 5V logic reference; isolates digital switching noise from analog paths and enables mixed-voltage system design. |
| 11 | Ground (GND) | Reference for logic inputs and internal biasing; must be tied to system ground plane for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents momentary short between NC and NO paths during switching - critical for protecting downstream circuitry in PBX and avionics signal matrices. |
| Rail-to-rail analog signal handling | Supports full V+ to V− swing without distortion or clipping - enables direct interfacing with op-amps and ADCs operating at supply rails. |
| 0.5Ω max RON match | Eliminates gain mismatch in dual-channel instrumentation amplifiers and balanced audio paths without trimming. |
| <5nA off-leakage at +85°C | Maintains >100MΩ effective isolation at elevated temperatures - essential for long-time-constant integrators and high-impedance sensor nodes. |
| Pin-compatible with DG403 | Enables drop-in replacement in legacy designs using DG403, with improved RON, leakage, and speed - no PCB rework required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4622CPE | Same pinout and electrical specs, but rated for 0°C to +70°C only - lacks extended temperature qualification. | Suitable for commercial-grade test fixtures or consumer audio gear; not qualified for industrial or military thermal environments. | Select MAX4622CPE only if ambient operating temperature remains within 0°C to +70°C and cost is prioritized over thermal margin. |
| ADG408BRZ | 8-channel single-pole analog switch (not dual SPDT); 45Ω typical RON; no break-before-make guarantee; requires external logic for SPDT emulation. | Better suited for high-channel-count multiplexing than dual-path routing; lacks NC/NO topology and guaranteed switching sequence. | Choose ADG408BRZ only when expanding beyond two switch pairs is needed and break-before-make is not required. |
Compared with MAX4622CPE, the MAX4622EPE+ adds guaranteed −40°C to +85°C operation and tighter leakage specs at temperature extremes; versus ADG408BRZ, it delivers native dual SPDT functionality with built-in break-before-make timing - eliminating external logic and reducing BOM count in routing-critical designs.

FAQ
What is the maximum supply voltage rating for MAX4622EPE+ in single-supply operation?
The MAX4622EPE+ supports a single positive supply from +4.5V to +36V. Absolute maximum rating is +44V referenced to GND, but operation above +36V violates the specified functional range and risks parametric degradation or reliability issues. For reliable long-term use, stay within the +4.5V to +36V range per the datasheet's Electrical Characteristics table.
Does MAX4622EPE+ require a separate logic supply (VL) when using TTL-level control inputs?
Yes, the MAX4622EPE+ requires VL to be connected to +5V even when driven by TTL logic. The VL pin powers the internal level-shifter and defines the logic threshold (0.8V/2.4V). Leaving VL unconnected or floating will cause undefined switching behavior and potential damage. Always tie VL to a stable +5V source, decoupled with a 0.1µF capacitor to GND.
Is break-before-make timing guaranteed for both switch pairs in MAX4622EPE+?
Yes, break-before-make timing is guaranteed for both SPDT switch pairs in the MAX4622EPE+. The datasheet specifies tD (delay between turn-off of one path and turn-on of the other) as 90ns to 200ns typical across temperature and supply conditions. This guarantee applies independently to Switches 1&2 and Switches 3&4, ensuring safe signal path isolation during transitions in dual-channel routing applications.
Can MAX4622EPE+ handle bipolar analog signals when operated from a single +12V supply?
No - when powered from a single +12V supply (V− = GND), the MAX4622EPE+ can only switch analog signals from GND to +12V. Bipolar signal handling (e.g., ±10V) requires dual supplies (e.g., V+ = +15V, V− = −15V). The rail-to-rail capability refers to spanning the full distance between the applied V+ and V− rails, not generating negative voltages from a single supply.
What is the thermal performance difference between MAX4622EPE+ and MAX4622CPE?
The MAX4622EPE+ is characterized and guaranteed for operation from −40°C to +85°C, while the MAX4622CPE is rated only from 0°C to +70°C. Key parameters like off-leakage (<5nA at +85°C) and RON match (0.5Ω max) are tested and warranted across the full −40°C to +85°C range for the E-grade part, making it suitable for industrial and automotive under-hood applications where C-grade parts would fail validation.
