Product details
Overview
The MAX4519ESD from Maxim Integrated is a dual 2-channel, precision CMOS analog multiplexer designed for low-voltage signal routing in high-fidelity data-acquisition and battery-operated systems. It features dual ±2.7V to ±8V or single +2.7V to +15V supply operation, <100Ω on-resistance (typ. 60Ω), <4Ω channel-to-channel on-resistance matching, <5pC charge injection, and rail-to-rail analog signal handling up to ±4.5V.
For engineers reviewing the MAX4519ESD datasheet, MAX4519ESD pinout, MAX4519ESD application, or MAX4519ESD equivalent, this page delivers verified specifications, temperature-rated package details (-40°C to +85°C), real-world leakage performance (<2nA NO-off at +85°C), and validated alternatives for precision analog switching in military, communications, and test equipment designs.
Technical Context
The MAX4519ESD implements two independent 2:1 analog switches with TTL/CMOS-compatible digital control (A0, A1, EN), enabling simultaneous or selective routing of two differential or single-ended signal paths. Its low-charge-injection architecture minimizes sampling error in sample-and-hold circuits, while matched on-resistance ensures consistent gain across channels in instrumentation front-ends.
Operating from extended-temperature SOIC-14 packaging, the device maintains guaranteed flat on-resistance (<10Ω variation over full signal range) and sub-5pC charge injection across -40°C to +85°C - critical for low-distortion audio routing and precision sensor multiplexing where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | <100Ω max (60Ω typ); ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| On-Resistance Matching | <4Ω between channels; preserves amplitude accuracy when switching between parallel signal chains. |
| Charge Injection | <5pC; limits voltage glitch on hold capacitors in sample-and-hold stages to <1mV with 1nF load. |
| NO-Off Leakage | <2nA at +85°C; prevents DC error accumulation in high-impedance sensor interfaces over temperature. |
| Analog Signal Range | Rail-to-rail: V– to V+; supports ±4.5V signals with ±5V supplies or 0V to 4.5V with +5V single supply. |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (dual); enables direct integration into mixed-supply industrial and portable systems. |
| Switching Speed | Transition time <250ns; suitable for multiplexing signals up to ~1MHz without significant settling delay. |
Pinout & Package
MAX4519ESD is supplied in a 14-pin SOIC package (SO-14, 150 mil width), rated for -40°C to +85°C operation. Pin 1 is A1; pin 14 is GND. The package is RoHS-compliant and moisture-sensitive level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Address Input 1 | Selects active channel pair (A1/A0 = 00 → COMA/NO1A & COMB/NO1B; 11 → COMA/NO2A & COMB/NO2B). |
| GND | Logic Ground Reference | Reference for all digital inputs (EN, A0, A1); must be tied to system ground, not floating. |
| V+ | Positive Supply Voltage | Accepts +2.7V to +15V; substrate tied internally to V+, requiring stable bypassing near pin. |
| NO1B | Normally Open Terminal B-Switch 1 | Analog input/output for first switch in B channel; connects to COMB when selected. |
| NO1A | Normally Open Terminal A-Switch 1 | Analog input/output for first switch in A channel; connects to COMA when selected. |
| V- | Negative Supply Voltage | Accepts -2.7V to -8V in dual mode; connect to GND for single-supply operation. |
| EN | Enable Logic Input | Active-high enable: EN = low disables both switches (high-impedance off-state). |
| A0 | Address Input 0 | LSB of 2-bit address; used with A1 to select one of four possible switch configurations. |
| NO2B | Normally Open Terminal B-Switch 2 | Analog input/output for second switch in B channel; connects to COMB when selected. |
| COMB | Common Terminal B-Switch | Shared analog node for B-side switches; routed to NO1B or NO2B based on A1/A0. |
| N.C. | Not Internally Connected | Pins 7, 8, 10, 11 are unconnected die pads; must remain floating or grounded per layout best practice. |
| COMA | Common Terminal A-Switch | Shared analog node for A-side switches; routed to NO1A or NO2A based on A1/A0. |
| NO2A | Normally Open Terminal A-Switch 2 | Analog input/output for second switch in A channel; connects to COMA when selected. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog voltages from V– to V+ without clipping - essential for full-scale sensor output capture. |
| Guaranteed on-resistance flatness | <10Ω variation over entire signal range (±4.5V), ensuring linear gain response in amplifier feedback paths. |
| ESD protection >2000V | HBM rating exceeds JEDEC JS-001 Class 2, reducing need for external TVS in board-level ESD hardening. |
| Low power consumption | <300µW typical supply current enables use in always-on monitoring nodes with µA-level budget constraints. |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V logic thresholds with <1µA input current - interoperable with 3.3V and 5V microcontrollers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher on-resistance (1.3Ω typ), wider supply range (±5V to ±22V), but higher charge injection (12pC). | Better suited for high-voltage industrial I/O modules; less ideal for precision low-voltage sampling. | Choose ADG1419BRUZ only if >±15V operation or higher breakdown voltage is required; otherwise MAX4519ESD offers superior low-signal fidelity. |
| TS5A23159DCKR | Lower voltage rating (+1.65V to +5.5V), smaller 6-pin SC70 package, but no dual-supply support and higher RON mismatch (15Ω). | Targeted at space-constrained consumer electronics; lacks extended temperature and bipolar capability. | TS5A23159DCKR fits ultra-compact PCBs but cannot replace MAX4519ESD in military or industrial environments requiring -40°C to +85°C and ±8V operation. |
Compared with ADG1419BRUZ and TS5A23159DCKR, the MAX4519ESD uniquely balances low charge injection, tight on-resistance matching, and extended-temperature bipolar operation - making it the only choice for precision, wide-range analog multiplexing in demanding embedded systems.

FAQ
What is the operating temperature range of the MAX4519ESD?
The MAX4519ESD is rated for operation from -40°C to +85°C, as indicated by the 'E' suffix in its part number. This extended temperature grade makes it suitable for industrial control systems, avionics subsystems, and outdoor communications equipment where ambient conditions exceed commercial-grade limits. All key parameters - including on-resistance matching and leakage current - are guaranteed across this full range.
Does the MAX4519ESD support single-supply operation?
Yes, the MAX4519ESD supports single-supply operation from +2.7V to +15V. In this configuration, the V– pin must be connected to GND. The device maintains rail-to-rail analog signal handling (0V to V+) and retains TTL/CMOS logic compatibility. Performance metrics such as on-resistance and switching speed are fully specified under single-supply conditions in the datasheet's Electrical Characteristics tables.
How does the MAX4519ESD differ from the MAX4518?
The MAX4519ESD is a dual 2-channel analog multiplexer (two independent 2:1 switches), whereas the MAX4518 is a 4-channel (one 4:1) device. Their pinouts, truth tables, and internal routing differ fundamentally: MAX4519ESD provides separate COMA/COMB and NOx-A/NOx-B terminals for true dual-path operation, while MAX4518 uses a single COM and four NO pins. This architectural distinction makes them functionally non-interchangeable without PCB redesign.
What is the maximum analog signal voltage the MAX4519ESD can handle?
The MAX4519ESD supports analog signals from V– to V+, with absolute maximum ratings of (V– – 0.3V) to (V+ + 0.3V). With ±5V supplies, this allows ±4.5V signal swing; with +5V/V– = GND, it supports 0V to 4.5V. Exceeding these limits risks forward-biasing internal ESD diodes and causing latch-up or permanent damage. Signal clamping must be implemented externally if overvoltage events are expected.
Is the MAX4519ESD pin-compatible with other Maxim multiplexers like the MAX4519CSD?
Yes, the MAX4519ESD is pin-compatible with all MAX4519 variants in the SO-14 package (e.g., MAX4519CSD, MAX4519EPD), sharing identical pinout, footprint, and electrical interface. The only differences are temperature grade (E = -40°C to +85°C), reliability screening, and qualification testing - making MAX4519ESD a direct drop-in replacement where extended temperature operation is required.
