Product details
Overview
MAX4669ESE+T 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 analog signal handling up to ±20V. It is used in reed relay replacement, test equipment, and audio-signal routing where low distortion and high reliability are required.
For engineers reviewing the MAX4669ESE+T datasheet, MAX4669ESE+T pinout, MAX4669ESE+T application, or MAX4669ESE+T equivalent, key selection criteria include guaranteed break-before-make timing, matched on-resistance (≤0.4Ω), off-isolation (–60dB), crosstalk (–66dB), and TTL/CMOS-compatible logic thresholds at ±15V or +12V supplies.
Technical Context
The MAX4669ESE+T implements two independent SPST switches in a single SOIC-16 package: Switch 1 is NC, Switch 2 is NO, with internal logic ensuring break-before-make transition to prevent momentary shorting. Its CMOS architecture uses matched P- and N-channel devices to achieve flat on-resistance (<0.5Ω variation) over the full ±20V analog range and low charge injection (450pC typical).
It supports dual-supply operation (±4.5V to ±20V) or single-supply (4.5V to 36V), with logic inputs referenced to VL (typically +5V) and compatible with TTL/CMOS thresholds (0.8V low / 2.4V high). All analog terminals (COM, NO, NC) tolerate signals from V– to V+, enabling true rail-to-rail switching without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±100mA continuous current. |
| RON Match Between Channels | 0.4Ω max - enables precise gain matching in differential or dual-path analog circuits without calibration. |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent attenuation and linearity across full signal swing in precision instrumentation. |
| Off-Isolation | –60dB at 1MHz - suppresses coupling from active to inactive channels in multiplexed signal routing. |
| Crosstalk | –66dB at 1MHz - prevents interference between simultaneously routed analog signals (e.g., stereo audio or dual sensor inputs). |
| Break-Before-Make Delay | 30ns max - guarantees no overlap between NC and NO conduction, critical for safe switching in power-sensitive or fault-tolerant systems. |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports industrial ±15V, automotive 24V, and legacy 12V systems without external regulators. |
Pinout & Package
MAX4669ESE+T is housed in a 16-pin narrow SOIC (SOICN) package, 3.9mm wide, with standard 1.27mm pitch. Pin 1 is marked by a notch or dot; device orientation follows JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Not internally bonded; must be connected to GND for optimal off-isolation and EMI suppression. |
| 2, 7 | IN1, IN2 | Digital control inputs - active-high logic drives Switch 1 (NC) and Switch 2 (NO); TTL/CMOS compatible at VL = +5V. |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower rail for rail-to-rail analog range. |
| 5 | GND | Analog/digital ground reference - separate from V− in dual-supply mode; requires low-impedance connection to minimize noise coupling. |
| 9, 16 | NC1, NO1 | Switch 1 terminals - NC1 is normally closed to COM1; NO1 is normally open; both rated for ±100mA continuous. |
| 11, 14 | COM1, COM2 | Common analog I/O nodes - bidirectional, support rail-to-rail signals from V− to V+; primary signal path entry/exit points. |
| 12 | VL | Logic supply input - powers internal level-shifters; typically +5V; decoupling capacitor required near pin. |
| 13 | V+ | Positive analog supply - defines upper rail; supports up to +36V in single-supply or +20V in dual-supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures zero overlap between NC and NO conduction in MAX4669ESE+T, eliminating transient shorts during state transitions in safety-critical signal routing. |
| Rail-to-rail analog signal handling | Supports input/output signals spanning V− to V+ (e.g., ±15V or 0V to +24V), enabling direct interface with op-amps, ADCs, and sensors without clamping or attenuation. |
| Low on-resistance flatness (0.5Ω max) | Maintains consistent insertion loss and THD across full signal range, critical for audio fidelity and precision measurement applications. |
| ESD protection >2kV (HBM) | Withstands electrostatic discharge per MIL-STD-883 Method 3015.7, reducing need for external protection in production test and field-deployed equipment. |
| TTL/CMOS-compatible logic inputs | Accepts standard logic levels at ±15V dual supply or +12V single supply without external level shifters, simplifying controller interface design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher RON (4.7Ω typ), no guaranteed break-before-make, but offers 150MHz bandwidth and lower charge injection (12pC). | Better suited for high-frequency RF sampling; less suitable for DC–audio switching requiring guaranteed B-B-M. | Select ADG1419BRUZ only when bandwidth >10MHz is mandatory and B-B-M is not required. |
| TS5A23157DGSR | Lower voltage rating (5.5V max), smaller 10-pin VSSOP package, and no dual-supply support - operates only on single 1.65V–5.5V rails. | Ideal for portable/battery-powered systems; incompatible with ±15V or 24V industrial buses. | Choose TS5A23157DGSR for space-constrained, low-voltage designs where rail-to-rail ±20V capability is unnecessary. |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4669ESE+T uniquely combines guaranteed break-before-make timing, ±20V dual-supply operation, and sub-3Ω on-resistance - making it the only option among the three qualified for high-voltage, safety-critical analog multiplexing in test and avionics systems.

FAQ
What is the guaranteed break-before-make timing specification for MAX4669ESE+T?
The MAX4669ESE+T guarantees a break-before-make time delay of 5ns to 30ns under dual-supply conditions (±15V) and 10ns to 500ns under single-supply conditions (+12V), as measured per Figure 2 in the datasheet. This timing ensures no overlap between NC and NO conduction, preventing transient short circuits during switching - a defining feature distinguishing MAX4669ESE+T from MAX4667ESE+T (dual NC) and MAX4668ESE+T (dual NO).
Can MAX4669ESE+T operate from a single +24V supply?
Yes, MAX4669ESE+T supports single-supply operation from +4.5V to +36V. When using +24V, connect V− to GND, set VL to +5V, and ensure logic inputs meet TTL/CMOS thresholds (0.8V low / 2.4V high). The analog signal range becomes 0V to +24V, and RON remains ≤4Ω (typical 3Ω) at VCOM = +10V, making MAX4669ESE+T suitable for 24V industrial control signal routing.
What is the maximum continuous current rating per switch terminal in MAX4669ESE+T?
Each switch terminal (COM1, COM2, NC1, NO1) in MAX4669ESE+T is rated for ±100mA continuous current, with ±300mA peak current allowed for 1ms pulses at 10% duty cycle. This rating applies across the full operating temperature range (–40°C to +85°C) and is validated under worst-case thermal conditions - confirming MAX4669ESE+T's suitability for driving moderate-power analog loads like transducer excitation or sensor biasing.
How does the on-resistance flatness of MAX4669ESE+T affect audio performance?
MAX4669ESE+T specifies on-resistance flatness of ≤0.5Ω over the ±10V signal range, meaning RON varies by less than 0.5Ω as the analog signal swings from –10V to +10V. This flatness minimizes harmonic distortion and preserves channel-to-channel gain tracking in audio routing - critical for professional audio mixers where THD must remain below 0.002% across the full dynamic range, directly enabled by the stable RON behavior of MAX4669ESE+T.
Is MAX4669ESE+T pin-compatible with other devices in the MAX4667/MAX4668/MAX4669 family?
Yes, MAX4669ESE+T shares identical pinout, package (16-pin narrow SOIC), and footprint with MAX4667ESE+T and MAX4668ESE+T. All three devices use the same SOICN layout shown in the datasheet top view, allowing board-level substitution without layout changes - though functional behavior differs (MAX4669ESE+T provides one NC + one NO with B-B-M, while MAX4667ESE+T is dual NC and MAX4668ESE+T is dual NO).
