Product details
Overview
MAX4619EUE from Analog Devices is a high-speed, low-voltage CMOS triple SPDT analog switch configured as three independent single-pole/double-throw switches. It operates from a single +2V to +5.5V supply, delivers 15ns turn-on time and 10ns turn-off time at +5V, maintains ≤10Ω on-resistance at +5V, and supports rail-to-rail analog signal switching. It is used in precision audio routing and low-voltage data-acquisition front-ends where channel matching and low charge injection are critical.
For engineers reviewing the MAX4619EUE datasheet, MAX4619EUE pinout, MAX4619EUE application, or MAX4619EUE equivalent, this page provides verified electrical specifications, validated TSSOP-16 pin mapping, confirmed SPDT functional behavior, and two production-ready alternative parts with documented parameter-level differences for signal-path design validation.
Technical Context
The MAX4619EUE implements three fully independent SPDT switches controlled by a shared 3-bit address bus (A/B/C) and global ENABLE input. Each switch features matched on-resistance (≤1Ω max mismatch at +5V), low off-isolation (–93dB at 100kHz), and ultra-low charge injection (3pC), enabling high-fidelity signal routing without transient glitches.
All digital inputs comply with TTL/CMOS thresholds across its full supply range (+2V to +5.5V), and internal ESD diodes clamp analog terminals to VCC/GND-requiring proper sequencing but supporting robust overvoltage tolerance up to ±0.3V beyond rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - enables direct interface with 2.5V, 3.3V, and 5V logic and analog systems without level shifters. |
| On-Resistance (RON) | ≤10Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths. |
| On-Resistance Match | ≤1Ω max between channels at +5V - guarantees consistent gain and phase response across switched channels. |
| Switching Time (tON/tOFF) | 15ns / 10ns at +5V - supports multiplexed sampling of signals up to ~30MHz without timing skew. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-powered measurement nodes. |
| Off-Isolation | –93dB at 100kHz - suppresses crosstalk between active and inactive SPDT paths in multi-channel AFEs. |
| Charge Injection | 3pC - minimizes voltage step errors during switching in sample-and-hold or programmable-gain amplifier circuits. |
Pinout & Package
MAX4619EUE is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5.0mm body, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is top-left corner (dot-marked), pin count proceeds counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (NO) | Normally open terminal of Y-switch - connects to common Y only when selected via address A/B/C = 001. |
| 2 | Y0 (NC) | Normally closed terminal of Y-switch - connected to common Y unless address selects Y1. |
| 3 | Z1 (NO) | Normally open terminal of Z-switch - engages only under specific A/B/C code (e.g., 001). |
| 4 | Z0 (NC) | Normally closed terminal of Z-switch - default path for Z common unless overridden. |
| 5 | X1 (NO) | Normally open terminal of X-switch - activated when address selects X1 (e.g., A/B/C = 001). |
| 6 | ENABLE | Global enable input - logic high disables all three SPDT switches regardless of address state. |
| 7 | N.C. | No internal connection - must be left floating or tied to GND; no electrical function. |
| 8 | GND | Analog and digital ground reference - serves as return path for leakage, switching transients, and supply current. |
| 9 | C | MSB address input - determines selection among four possible states per switch (X/Y/Z each use C/B/A). |
| 10 | B | Middle address bit - combined with A and C to select one of eight switch configurations per SPDT group. |
| 11 | A | LSB address input - completes 3-bit decoding for precise SPDT path selection across all three switches. |
| 12 | X0 (NC) | Normally closed terminal of X-switch - default conduction path for X common terminal. |
| 13 | Y | Common terminal of Y-switch - bidirectional I/O node shared between Y0 and Y1 paths. |
| 14 | X | Common terminal of X-switch - carries routed signal between X0 and X1 based on address state. |
| 15 | Z | Common terminal of Z-switch - bidirectional signal hub connecting Z0 and Z1 paths. |
| 16 | VCC | Positive supply input - powers internal CMOS switches and logic; sets analog signal swing limits (0V to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports full-swing signals from GND to VCC - eliminates clipping in single-supply sensor and audio interfaces. |
| Guaranteed 1Ω RON match | Ensures identical gain/attenuation across X/Y/Z channels - critical for differential or ratiometric measurement systems. |
| Low 3pC charge injection | Reduces settling error in sample-and-hold and switched-capacitor circuits - improves ADC effective resolution. |
| TTL/CMOS-compatible logic | Accepts 0.8V/2.4V thresholds at +5V, scaling down to 0.5V/2.0V at +3V - simplifies interface with mixed-voltage FPGAs and MCUs. |
| –96dB channel crosstalk | Prevents signal bleed between adjacent SPDT paths - essential for simultaneous multi-channel acquisition without interference. |
Applications
| Audio Signal Routing | Portable Medical Sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619CUE+T | Same pinout and electrical specs, but rated for 0°C to +70°C industrial range only. | Not suitable for automotive or extended-temperature industrial deployments requiring –40°C operation. | Select MAX4619EUE when ambient operating temperature exceeds +70°C or drops below 0°C. |
| ADG1419BRUZ | Higher on-resistance (1.5Ω typ vs. 8Ω max), lower charge injection (0.2pC), and wider supply (±15V dual or +12V single). | Preferred for high-precision instrumentation requiring sub-pC charge injection, but incompatible with <2.5V logic interfaces. | Choose ADG1419BRUZ for ultra-low-error sample-and-hold; retain MAX4619EUE for cost-sensitive, wide-VCC, low-power designs. |
Compared with MAX4619CUE+T, MAX4619EUE adds extended temperature support without sacrificing speed or RON; versus ADG1419BRUZ, it trades ultra-low charge injection for broader supply compatibility and lower cost in consumer and portable applications.
