Product details
Overview
MAX4519EEE from Maxim Integrated is a dual 2-channel precision CMOS analog multiplexer designed for low-distortion signal routing in battery-powered and precision instrumentation systems. It delivers <100Ω on-resistance (typ. 60Ω), <4Ω channel-to-channel matching, <5pC charge injection, rail-to-rail signal handling, and operates from single +2.7V to +15V or bipolar ±2.7V to ±8V supplies - enabling use in low-voltage data-acquisition and military radio front-ends.
For engineers reviewing the MAX4519EEE datasheet, MAX4519EEE pinout, MAX4519EEE application, or MAX4519EEE equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), NO-off leakage <2nA at +85°C, break-before-make timing (90–245ns), QSOP-16 package compatibility, and dual-supply operation with TTL/CMOS logic inputs.
Technical Context
The MAX4519EEE implements two independent 2:1 analog switches controlled by A0/A1 address lines and a global EN enable input, supporting simultaneous switching of two differential or independent signal paths. Its silicon-gate CMOS process ensures electrostatic discharge protection >2000V and guarantees low charge injection (<5pC) critical for sample-and-hold accuracy.
It supports true rail-to-rail analog signal ranges up to ±4.5V (dual supply) or 0V to V+ (single supply), with COM-Off leakage <5nA and NO-Off leakage <2nA at +85°C - making it suitable for high-impedance sensor interfaces and low-power portable systems where leakage-induced offset drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 60Ω typ. (max 100Ω); enables low insertion loss & minimal gain error in precision signal chains |
| On-Resistance Matching | <4Ω between channels; ensures matched gain/attenuation in differential or dual-path routing |
| Charge Injection | <5pC; limits voltage glitch and settling error in sample-and-hold and ADC front-end applications |
| NO-Off Leakage | <2nA at +85°C; preserves signal integrity in high-Z sensor and battery-monitoring circuits |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (bipolar); supports wide-input-range industrial and military power architectures |
| Transition Time | <250ns; allows fast channel switching in automatic test equipment and comms signal routing |
| Logic Compatibility | TTL/CMOS inputs (VIH ≥2.4V, VIL ≤0.8V); simplifies interface with microcontrollers and FPGAs without level-shifting |
Pinout & Package
MAX4519EEE is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), rated for -40°C to +85°C operation. Pin functions are validated per Maxim's official pin configuration diagram and functional truth table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting active NOx-A/NOx-B channel pair; logic-compatible with 3.3V/5V controllers |
| 2, 15 | GND, V+ | Logic ground reference and positive supply input; V+ connects substrate for ESD robustness |
| 3, 14 | V-, EN | Negative supply (or GND for single supply); EN enables/disables both switch banks simultaneously |
| 4, 5, 12, 13 | NO1A, NO1B, NO2A, NO2B | Four normally-open analog inputs - grouped as two independent 2:1 muxes (A and B banks) |
| 8, 9 | COMA, COMB | Two common output terminals - one per switch bank; support bidirectional rail-to-rail signal flow |
| 6, 7, 10, 11 | N.C. | Not internally connected; no internal bonding or circuitry - must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V- to V+ without clipping - essential for full-scale sensor and audio routing |
| Guaranteed on-resistance flatness | <10Ω variation over full signal range - maintains consistent gain/attenuation across input voltage swing |
| Break-before-make switching | 90–245ns interval prevents momentary shorting during channel transitions - protects sensitive sources |
| Low power consumption | <300µW typical - extends battery life in portable test gear and handheld instrumentation |
| ESD protection | >2000V HBM - eliminates need for external protection diodes in ruggedized military and industrial designs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG721BRMZ | Single 2:1 CMOS switch; 4Ω on-resistance (lower), but no dual-bank architecture or EN pin | Requires two devices and external logic to replicate MAX4519EEE's dual-channel synchronous control | Select when ultra-low RON and minimal footprint outweigh need for integrated dual control |
| TS5A23157DCUR | Single-supply only (+1.65V to +5.5V); 0.9Ω RON, but no bipolar support or guaranteed flatness spec | Not suitable for ±5V signal routing or precision sample-and-hold where flat RON is critical | Prefer for low-voltage consumer electronics where cost and RON dominate over temp stability and leakage |
Compared with ADG721BRMZ and TS5A23157DCUR, the MAX4519EEE uniquely combines dual synchronized 2:1 switching, bipolar supply capability, guaranteed on-resistance flatness (<10Ω), and sub-2nA leakage at +85°C - making it the only option qualified for military-grade signal routing and precision instrumentation requiring correlated channel performance.

FAQ
What is the operating temperature range of the MAX4519EEE?
The MAX4519EEE is specified for operation from -40°C to +85°C. This extended industrial temperature grade is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. The device uses Maxim's low-voltage silicon-gate process to maintain parameter stability across this full range, including leakage and on-resistance specs.
Does the MAX4519EEE support single-supply operation?
Yes, the MAX4519EEE supports single-supply operation from +2.7V to +15V. In this mode, V- must be connected to GND. Electrical characteristics - including on-resistance (225Ω max at +3V), leakage, and switching times - are fully characterized and guaranteed for single-supply configurations per the "ELECTRICAL CHARACTERISTICS-Single +3V Supply" and "Single +5V Supply" tables.
How many analog channels does the MAX4519EEE control?
The MAX4519EEE controls two independent 2:1 analog multiplexer banks (A and B), each with its own common terminal (COMA, COMB) and two normally-open inputs (NO1A/NO2A and NO1B/NO2B). This dual-bank architecture allows simultaneous routing of two separate signals - distinct from the 4-channel MAX4518 - and is explicitly defined in the General Description and Pin Configurations sections.
What is the maximum allowable supply voltage difference for the MAX4519EEE?
The MAX4519EEE permits a maximum voltage difference of 17V between V+ and V-, as stated in the Absolute Maximum Ratings table. For example, +10V and -5V (ΔV = 15V) is acceptable, but +12V and -6V (ΔV = 18V) exceeds the rating and risks permanent damage. This limit applies regardless of whether supplies are balanced or unbalanced.
Is the MAX4519EEE pin-compatible with other devices in the MAX4518/MAX4519 family?
No - the MAX4519EEE is not pin-compatible with the MAX4518 variants. While both use 16-pin QSOP packages, their pinouts differ fundamentally: MAX4518 has NO1–NO4 and single COM, whereas MAX4519EEE assigns pins to NO1A/NO2A/NO1B/NO2B and dual COMA/COMB. This is clearly shown in the "Pin Configurations" diagrams and "Pin Description" table, confirming distinct physical layouts.
