Product details
Overview
MAX4669ESE from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, guaranteeing break-before-make operation. It features 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±20V. It is used in reed relay replacement, test equipment, and audio-signal routing where low distortion and guaranteed switching sequence are critical.
For engineers reviewing the MAX4669ESE datasheet, MAX4669ESE pinout, MAX4669ESE application, or MAX4669ESE equivalent, key selection criteria include verified break-before-make timing (5–30 ns), matched on-resistance (≤0.4Ω), off-isolation (−60 dB), crosstalk (−66 dB), and SOIC-16 package compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The MAX4669ESE implements two independent SPST switches in a single SOIC-16 package: Switch 1 is NC (pin 9 → COM1 → pin 14), Switch 2 is NO (pin 16 → COM2 → pin 11), with logic-controlled IN1 (pin 7) and IN2 (pin 2). Break-before-make is hardware-guaranteed via internal timing control, eliminating contact bounce during channel switching.
It supports dual-supply operation (±4.5V to ±20V) or single-supply (4.5V to 36V), with TTL/CMOS-compatible inputs (VIN_H = 2.4V, VIN_L = 0.8V) referenced to VL (pin 12). Analog signal range spans V− to V+ (e.g., −20V to +20V under dual supply), and all terminals tolerate overvoltage clamping via internal diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss at 10mA load current |
| RON Match Between Channels | 0.4Ω max - enables precise gain/phase matching in differential or dual-path signal routing |
| RON Flatness | 0.5Ω max over full signal range - maintains consistent attenuation across rail-to-rail input voltages |
| Break-Before-Make Delay | 5–30 ns - prevents momentary short-circuit between channels during state transition |
| Off-Isolation | −60 dB at 1MHz - suppresses signal coupling from OFF channel into active path |
| Crosstalk | −66 dB at 1MHz - minimizes interference between adjacent switched signals |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports wide industrial and test-system voltage rails |

Pinout & Package
MAX4669ESE is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for surface-mount reflow. Pin 1 is marked by notch or dot; thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Not internally bonded; tie to GND for improved isolation and EMI performance |

| 4 | V− | Negative analog supply; connect to GND for single-supply operation |
| 5 | GND | Analog/digital reference ground common to all supplies and logic |
| 7 | IN1 | Digital control input for NC1 switch (active-high logic) |
| 9 | NC1 | Normally closed terminal of Switch 1 - connects to COM1 when IN1 = low |
| 11 | COM2 | Common terminal of Switch 2 (NO type) - routes signal to NO2 when IN2 = high |
| 12 | VL | Logic supply reference - must be ≥2.7V and ≤V+ for valid input thresholds |
| 13 | V+ | Positive analog supply - sets upper rail for analog signal range |
| 14 | COM1 | Common terminal of Switch 1 (NC type) - connects to NC1 when IN1 = low |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (±5V to ±22V dual not supported); 1.8Ω RON; no break-before-make guarantee | Optimized for low-RON precision instrumentation; lacks hardware-enforced switching sequencing | Select when lowest on-resistance is primary; verify external timing control for sequential switching |

FAQ
What is the guaranteed break-before-make timing specification for MAX4669ESE?
The MAX4669ESE guarantees a break-before-make time delay of 5ns minimum to 30ns maximum between its NC1 and NO1 channels. This hardware-enforced dead time is validated across −40°C to +85°C and ±4.5V to ±20V dual-supply operation. The timing ensures no overlap in conduction states, preventing short-circuit transients. This specification is explicitly tested and guaranteed per the MAX4669ESE datasheet Section "Electrical Characteristics-Dual Supplies", parameter "Break-Before-Make Time Delay (MAX4669)".
Can MAX4669ESE operate from a single +12V supply?
Yes, MAX4669ESE supports single-supply operation from +4.5V to +36V. With V+ = +12V and V− tied to GND, it delivers rail-to-rail analog switching from 0V to +12V. Logic inputs remain TTL/CMOS-compatible when VL = +5V, and key parameters-including 4Ω max on-resistance, 0.5nA max off-leakage at +85°C, and −60dB off-isolation-are fully specified under this condition per the "Electrical Characteristics-Single Supply" table in the MAX4669ESE datasheet.
What is the maximum analog signal voltage range supported by MAX4669ESE?
The MAX4669ESE supports analog signals from V− to V+, enabling true rail-to-rail operation. Under ±15V dual supply, the signal range is −15V to +15V; under ±20V, it extends to −20V to +20V. In single-supply mode (+12V), the range is 0V to +12V. Input voltages beyond these rails are clamped by internal diodes, but sustained overvoltage risks damage. Absolute maximum ratings limit V+ to +44V and V− to −44V relative to GND.
How does MAX4669ESE handle logic-level compatibility with microcontrollers?
MAX4669ESE provides TTL/CMOS-compatible logic inputs with guaranteed thresholds of VIN_L ≤ 0.8V and VIN_H ≥ 2.4V when VL = +5V. This allows direct interfacing with 3.3V and 5V microcontrollers, FPGAs, and CPLDs without level-shifting circuitry. Input leakage remains below ±0.5µA across temperature, minimizing drive burden. The logic supply VL must be independently decoupled and maintained within 2.7V to V+ to ensure proper threshold referencing per the MAX4669ESE functional diagram and truth table.
What package type and footprint does MAX4669ESE use?
MAX4669ESE uses a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, also designated SOICN or SO/DIP, with 1.27mm lead pitch and JEDEC MS-012AC outline. Its body dimensions are 10.3mm × 5.3mm × 1.75mm (L × W × H), compatible with standard SOIC-16 footprints. The device has no thermal pad, and pin 1 is identified by a notch or dot. This package is RoHS-compliant and qualified for reflow soldering per J-STD-020.
