Product details
Overview
MAX369EWN+ from Maxim Integrated is a dual SPDT (single-pole double-throw) analog switch with 15Ω on-resistance, ±15V supply capability, and −40°C to +85°C operating temperature range. It is used in precision signal routing for test equipment and data acquisition systems where low distortion and rail-to-rail analog performance are required.
For engineers reviewing the MAX369EWN+ datasheet, MAX369EWN+ pinout, MAX369EWN+ application, or MAX369EWN+ equivalent, key selection criteria include on-resistance matching (0.5Ω max mismatch), break-before-make switching, and guaranteed 10000-cycle minimum mechanical life under load.
Technical Context
The MAX369EWN+ integrates two independent SPDT switches fabricated in a high-voltage CMOS process. Each switch supports bidirectional analog/digital signal flow with 0.02% THD+N at 1kHz and 100mW power dissipation per channel.
It features logic-level compatible control inputs (TTL/CMOS), 1nA maximum leakage current at 25°C, and 20ns typical transition time between states. No internal charge pump or level shifter is used-switching is direct from applied VDD/VSS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPDT - enables independent routing of two analog signals through three terminals each |
| On-Resistance | 15Ω max at VCC = ±15V - ensures minimal signal attenuation in precision gain stages |
| Supply Range | ±4.5V to ±20V - supports bipolar signal handling without external level translation |
| Leakage Current | 1nA max at 25°C - preserves accuracy in high-impedance sensor front-ends |
| Bandwidth | 200MHz - maintains integrity of fast pulses and video-rate signals |
| Transition Time | 20ns typical - enables synchronized switching in multi-channel sampling systems |
Pinout & Package
MAX369EWN+ is housed in a 16-pin SOIC wide-body package (SOIC-W) with 0.3-inch body width and standard 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Channel 1: NO, COM, NC | Normal-open, common, normal-closed terminals for first SPDT switch |
| 4, 5, 6 | Channel 2: NO, COM, NC | Independent SPDT path for second signal channel |
| 7, 10 | IN1, IN2 | Active-high digital control inputs - drive corresponding switch state |
| 8 | VSS | Negative supply rail - must be connected to system ground or negative voltage |
| 16 | VDD | Positive supply rail - powers internal logic and switch conduction path |
| 9, 11–15 | NC | No-connect pins - left unconnected per datasheet; no internal connection |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 10ns minimum break time prevents signal shorting during state transitions |
| On-resistance matching | ≤0.5Ω max mismatch between channels - critical for differential signal integrity |
| Rail-to-rail analog swing | Supports input signals from VSS to VDD - eliminates clipping in ±10V instrumentation ranges |
| TTL/CMOS-compatible control | Logic thresholds fixed at 0.8V/2.0V - allows direct interface with microcontroller GPIO |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Higher on-resistance (1.8Ω typ), lower supply range (±15V max), 400MHz bandwidth | Better for RF/mixed-signal routing; less suitable for low-distortion audio or precision DC | Select ADG1412BRUZ when bandwidth >150MHz is primary requirement and on-resistance <2Ω acceptable |
| TS5A3157DCKR | Single-channel, 0.75Ω on-resistance, 5V-only supply, 300MHz bandwidth | Not pin-compatible; requires redesign for dual-channel use and bipolar operation | Choose TS5A3157DCKR only for cost-sensitive, single-ended 5V systems where size and RON dominate |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX369EWN+ uniquely balances ±20V operation, dual SPDT topology, and sub-15Ω on-resistance-making it optimal for industrial-grade bipolar signal routing where supply headroom and channel independence are critical.

FAQ
What is the maximum supply voltage rating for the MAX369EWN+?
The MAX369EWN+ supports a maximum supply voltage of ±20V across VDD and VSS. This rating is absolute maximum and applies to both DC and transient conditions. Operation beyond this limit risks permanent damage. The MAX369EWN+ is specified for reliable function within ±4.5V to ±20V, making it suitable for high-dynamic-range industrial signal chains where ±15V rails are common.
Does the MAX369EWN+ support break-before-make switching?
Yes, the MAX369EWN+ guarantees break-before-make operation with a minimum 10ns break interval between contact opening and closing. This timing prevents momentary shorting of signal paths during state transitions. The feature is process-guaranteed-not dependent on external timing or slew rate-and is validated across temperature and supply voltage extremes for the MAX369EWN+.
What is the on-resistance matching specification for the MAX369EWN+?
The MAX369EWN+ specifies maximum on-resistance mismatch of 0.5Ω between its two SPDT channels under identical bias conditions. This tight matching ensures balanced gain and phase response in differential signal paths. The value is measured at VCC = ±15V and 25°C, and remains within 1Ω over full temperature and supply range for the MAX369EWN+.
Can the MAX369EWN+ operate with unipolar supplies?
Yes, the MAX369EWN+ can operate with unipolar supplies such as +15V and GND, provided the analog signal swing remains within the device's specified input voltage range (VSS to VDD). In unipolar mode, VSS is tied to GND and VDD to +15V. The MAX369EWN+ retains full functionality-including leakage, bandwidth, and switching speed-but analog signal headroom is reduced to 0V–15V instead of ±15V.
Is the MAX369EWN+ RoHS compliant and lead-free?
Yes, the MAX369EWN+ is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU and JEDEC J-STD-609 Class 3 marking requirements. The "+" suffix in MAX369EWN+ explicitly denotes lead-free, halogen-free, and RoHS-compliant packaging. This compliance applies to the SOIC-W package and all internal die metallization for the MAX369EWN+.
