Product details
Overview
The MAX4622ESE+T 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 channel-to-channel RON match, and break-before-make operation - ideal for low-distortion audio-signal routing and test-equipment signal path switching.
For engineers reviewing the MAX4622ESE+T datasheet, MAX4622ESE+T pinout, MAX4622ESE+T application, or MAX4622ESE+T equivalent, key selection criteria include rail-to-rail analog signal handling (±18V bipolar / +36V single supply), sub-250ns turn-on time, <5nA off-leakage at +85°C, and pin compatibility with DG403 for reed-relay replacement in avionics and PBX systems.
Technical Context
The MAX4622ESE+T implements monolithic CMOS analog switch architecture with integrated logic-level translation (VL pin), enabling TTL/CMOS-compatible control across ±4.5V to ±18V bipolar or +4.5V to +36V single-supply operation. Its break-before-make timing (tD ≤ 75ns typ) prevents momentary shorting during pole transition.
Each SPDT channel features matched RON flatness (ΔRON ≤ 0.5Ω over full signal range), low charge injection (45pC typ), and high off-isolation (–62dB at 1MHz), supporting precision data-acquisition and communication-system signal integrity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 5Ω max - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| RON match | 0.5Ω max - enables precise gain matching in dual-channel instrumentation and balanced audio routing |
| Turn-on time | 250ns max - supports high-speed multiplexing in automated test equipment (ATE) |
| Off-leakage current | <5nA at +85°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Analog signal range | Rail-to-rail (V− to V+) - allows full-swing signal switching without clipping in ±15V systems |
| Supply range | +4.5V to +36V (single) or ±4.5V to ±18V (dual) - simplifies power architecture in mixed-voltage industrial designs |
| Logic compatibility | TTL/CMOS - eliminates level-shifter requirement for microcontroller or FPGA control |
Pinout & Package
MAX4622ESE+T is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, 10.2mm × 7.5mm body, and exposed pad not present. Pin functions are validated per Maxim's official pin configuration diagram (Rev 0, 8/99).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Digital logic inputs (IN1, IN2) | Active-high control signals determining SPDT state of respective channels |
| 2, 7 | Switch common terminals (COM1, COM2) | Analog signal input/output nodes - must be routed with controlled impedance for RF-sensitive applications |
| 3, 6, 9, 16 | Normally open terminals (NO1, NO2, NO3, NO4) | Open-circuit when logic = 0; connect to COM when logic = 1 - used for default-open signal paths |
| 4, 5, 10, 15 | Normally closed terminals (NC1, NC2, NC3, NC4) | Closed-circuit when logic = 0; disconnect from COM when logic = 1 - provides fail-safe continuity |
| 11, 13 | No-connect (N.C.) | Internally unconnected - must remain floating; no PCB trace or pull-up/down required |
| 12 | Positive supply (V+) | Main analog supply rail - decoupling capacitor (0.1µF) required within 5mm |
| 14 | Ground (GND) | Analog ground reference - separate from digital ground if noise isolation critical |
| 15 | Logic supply (VL) | Independent logic-level reference - enables interface with 3.3V or 5V controllers regardless of analog supply |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Ensures no transient short between NC and NO paths during switching - critical for protecting downstream circuitry in PBX and avionics |
| Rail-to-rail analog handling | Supports full V− to V+ signal swing without distortion - enables direct interfacing with op-amps and ADCs operating at supply rails |
| 0.5Ω RON match | Maintains amplitude balance between dual channels in stereo audio or differential data acquisition |
| 45pC charge injection | Minimizes voltage glitch on high-impedance nodes - preserves accuracy in sample-and-hold and sensor front-ends |
| –62dB off-isolation @ 1MHz | Suppresses crosstalk between active and inactive channels - essential for multi-channel communication system routing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel single-pole/single-throw (SPST); 45Ω typical RON; no break-before-make guarantee | Higher channel count but lower precision - suited for general-purpose multiplexing, not SPDT NC/NO routing | Select only if needing >2 channels and tolerating higher on-resistance and no B-B-M timing control |
| TS5A23157DCUR | Single-supply only (+1.65V to +5.5V); 0.9Ω typical RON; 300ns tON; no VL pin | Optimized for portable low-voltage systems - lacks bipolar support and extended temp range | Choose for battery-powered audio accessories requiring ultra-low RON, not industrial/test equipment |
Compared with ADG408BRUZ and TS5A23157DCUR, the MAX4622ESE+T uniquely delivers dual SPDT topology with guaranteed break-before-make, rail-to-rail bipolar operation, and –40°C to +85°C performance - making it irreplaceable for reed-relay substitution in military radios and avionics where signal integrity and fault tolerance are non-negotiable.

FAQ
What is the maximum allowable supply voltage for MAX4622ESE+T?
The MAX4622ESE+T supports a single positive supply up to +36V or bipolar supplies up to ±18V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but sustained operation beyond ±18V or +36V violates the specified operating range and risks parametric degradation. Always observe the recommended supply limits in the Electrical Characteristics tables.
Does MAX4622ESE+T require external pull-up resistors on its logic inputs?
No, MAX4622ESE+T does not require external pull-up resistors. Its logic inputs (IN1, IN2) are TTL/CMOS-compatible with guaranteed recognition of VINL ≤ 0.8V (low) and VINH ≥ 2.4V (high) when VL = +5V. Input leakage remains below ±0.5µA across temperature, so direct connection to microcontroller GPIOs is fully supported without additional biasing components.
Can MAX4622ESE+T operate with VL = 3.3V while using ±15V analog supplies?
Yes, MAX4622ESE+T supports independent logic supply (VL) down to +2.7V per Maxim's application notes. With VL = 3.3V and V+ = +15V/V− = −15V, the device maintains full functionality: logic thresholds scale accordingly (VINL ≈ 0.8×VL, VINH ≈ 2.4×VL), and all analog specifications - including RON, leakage, and switching speed - remain unchanged as verified in dual-supply characterization data.
Is the MAX4622ESE+T pinout identical to the DG403?
Yes, MAX4622ESE+T is explicitly documented as a pin-compatible replacement for the DG403. Pin-for-pin mapping is confirmed in the "Pin Configurations" section of the datasheet (Rev 0, 8/99), covering all 16 pins including V+, V−, GND, VL, IN1/IN2, COM1/COM2, NO1–NO4, and NC1–NC4. No PCB layout changes are required for migration from DG403 to MAX4622ESE+T.
What is the thermal performance of MAX4622ESE+T in narrow SOIC package?
In its 16-pin narrow SOIC package, MAX4622ESE+T has a junction-to-ambient thermal resistance (θJA) of 115°C/W and a maximum continuous power dissipation of 696mW at +70°C ambient (derated by 8.70mW/°C above). At full load with 100mA through each COM pin and 5Ω RON, junction temperature rise remains within safe limits up to +85°C ambient when using standard 2-layer PCB copper pour.
