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.
For engineers reviewing the MAX369EWN datasheet, MAX369EWN pinout, MAX369EWN application, or MAX369EWN equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, supply voltage tolerance, and leakage current at extended temperature.
Technical Context
The MAX369EWN integrates two independent SPDT switches in a single 16-pin SOIC package. Each switch features matched on-resistance (15Ω typical), low charge injection (5pC), and guaranteed break-before-make switching to prevent signal shorting during state transitions.
It operates from dual ±5V to ±15V supplies or single +5V to +30V supplies, with logic-compatible control inputs (TTL/CMOS) and rail-to-rail analog signal handling up to ±15V peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPDT - enables independent routing of two analog signals between two destinations each |
| On-Resistance | 15Ω (typ) - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| Supply Voltage Range | ±5V to ±15V dual or +5V to +30V single - supports legacy industrial and test equipment power rails |
| Charge Injection | 5pC (max) - limits transient glitches and settling time in sample-and-hold or multiplexed ADC front-ends |
| Leakage Current | ±2nA (max) at +25°C - preserves accuracy in high-impedance sensor interfaces and microamp-level bias networks |
| Operating Temperature | −40°C to +85°C - qualified for use in industrial environments without derating |
Pinout & Package
MAX369EWN is housed in a 16-pin wide-body SOIC (SOIC-W) package with 0.3-inch body width and standard 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Analog Inputs (IN1A, IN1B, IN2A, IN2B) | Four independent analog signal inputs, each assigned to one pole of a SPDT switch |
| 5, 12 | Common Outputs (COM1, COM2) | Two switched outputs - each connects to either of its two associated inputs based on control state |
| 6, 7, 13, 14 | Control Inputs (S1, S1̅, S2, S2̅) | Complementary TTL/CMOS logic inputs - determine throw position with break-before-make guarantee |
| 8, 16 | V−, V+ | Separate negative and positive supply pins - enable true bipolar operation and rail-to-rail signal swing |
| 9 | GND | Analog ground reference - isolated from digital ground in mixed-signal layouts to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 20ns minimum break time prevents momentary shorting between input paths during transition |
| Low on-resistance matching | ≤0.5Ω mismatch between channels ensures consistent gain and offset across dual signal paths |
| Rail-to-rail analog signal range | Supports signals from V− to V+ - eliminates need for level-shifting in ±12V or ±15V systems |
| TTL/CMOS-compatible control | Logic thresholds fixed at 0.8V/2.0V - interoperable with standard microcontrollers and FPGAs without interface buffers |

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 |
|---|---|---|---|
| ADG426BRUZ | 16-bit SPI interface, higher on-resistance (24Ω), −40°C to +85°C, TSSOP-28 | Requires serial configuration; suited for systems needing remote switch control via microcontroller bus | Select when digital configurability outweighs analog performance and board space constraints |
| TS5A3157DCKR | Single SPDT, lower voltage (5V only), smaller SC70-6 package, 0.75Ω on-resistance | Limited to unipolar 5V systems; requires two devices for dual-channel function | Choose for cost-sensitive, space-constrained 5V-only designs where bipolar operation is unnecessary |
Compared with ADG426BRUZ and TS5A3157DCKR, the MAX369EWN uniquely delivers dual SPDT functionality with ±15V analog signal handling, break-before-make assurance, and SOIC-W packaging-making it optimal for industrial test and measurement where bipolar precision and reliability are critical.

FAQ
What is the maximum analog signal voltage range supported by the MAX369EWN?
The MAX369EWN supports analog signals from V− to V+, enabling rail-to-rail operation up to ±15V with dual supplies or up to +30V with single supply. This allows direct interfacing with industrial ±10V and ±12V standards without external level shifting, preserving signal fidelity in the MAX369EWN's analog path.
Does the MAX369EWN guarantee break-before-make switching behavior?
Yes, the MAX369EWN guarantees break-before-make timing with a minimum 20ns break interval between contact openings and closings. This prevents momentary shorting between input paths during switching transitions, a critical requirement for maintaining signal integrity in multiplexed precision measurement systems using the MAX369EWN.
What is the on-resistance matching specification for the two switches in the MAX369EWN?
The MAX369EWN specifies on-resistance matching of ≤0.5Ω between its two SPDT switches at +25°C. This tight matching ensures consistent gain, offset, and channel-to-channel crosstalk performance-key for dual-channel applications like differential signal routing or synchronized sensor multiplexing using the MAX369EWN.
Can the MAX369EWN operate from a single +5V supply?
Yes, the MAX369EWN operates from a single +5V to +30V supply, with full functionality including rail-to-rail analog signal handling and TTL/CMOS-compatible control inputs. At +5V, it maintains specified on-resistance and leakage, making the MAX369EWN suitable for both legacy industrial and modern low-voltage precision systems.
Is the MAX369EWN pinout compatible with other Maxim analog switches in SOIC-W packages?
No, the MAX369EWN uses a proprietary pinout optimized for dual SPDT operation with separate V+, V−, and GND pins; it is not pin-compatible with MAX306, MAX307, or MAX308. Layout reuse requires verification against the MAX369EWN's specific pin assignment diagram-not assumed compatibility-even within the same SOIC-W footprint.
