Product details
Overview
The MAX4519ESD+ from Maxim Integrated is a precision dual 2-channel CMOS analog multiplexer with rail-to-rail signal handling, <100Ω on-resistance (typ. 60Ω), <4Ω channel-to-channel on-resistance matching, <5pC charge injection, and operation from ±2.7V to ±8V or +2.7V to +15V supplies - used in low-voltage data-acquisition systems and battery-operated test equipment.
For engineers reviewing the MAX4519ESD+ datasheet, MAX4519ESD+ pinout, MAX4519ESD+ application, or MAX4519ESD+ equivalent, this page delivers verified electrical specs, QSOP-16 pin mapping, leakage performance at +85°C, enable timing behavior, and real-world substitution guidance for analog signal routing designs.
Technical Context
The MAX4519ESD+ implements two independent 2:1 analog switches controlled by A0/A1 address lines and a global EN input, supporting break-before-make switching with <40ns typical tOPEN. Its low-charge-injection architecture minimizes voltage glitching in sample-and-hold circuits, while matched on-resistance ensures consistent gain across channels in instrumentation front-ends.
It operates across industrial temperature range (–40°C to +85°C), supports single- or dual-supply biasing, and features TTL/CMOS-compatible logic inputs with <0.1µA input current. The device uses Maxim's low-voltage silicon-gate process to guarantee ESD protection >2000V and <2nA NO-off leakage at +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 60Ω typ. at V± = ±5V - enables <1 LSB error in 12-bit ADC front-end designs with ≤1kΩ source impedance |
| On-Resistance Matching (∆RON) | <4Ω max - ensures ≤0.04% gain mismatch between parallel signal paths |
| Charge Injection (Q) | <5pC max - limits hold-mode voltage step to <500µV on 10nF sampling capacitor |
| NO-Off Leakage Current | <2nA at +85°C - contributes <2µV offset drift in high-Z sensor interfaces |
| Supply Range | +2.7V to +15V single or ±2.7V to ±8V dual - supports portable and industrial rails without level-shifting |
| Transition Time (tTRANS) | <250ns max - allows multiplexing of signals up to ~1.5MHz without significant edge distortion |
| Logic Compatibility | TTL/CMOS - interfaces directly with FPGA I/O banks and microcontroller GPIOs without buffers |
Pinout & Package
MAX4519ESD+ is housed in a 14-pin SOIC package (SO-14), with pin 1 as A1, pin 2 as GND, pin 3 as V+, pin 4 as NO1B, pin 5 as NO1A, pin 6 as V−, pin 7 as EN, pin 8 as A0, pin 9 as NO2B, pin 10 as COMB, pin 11 as NC, pin 12 as NC, pin 13 as COMA, and pin 14 as NO2A. All NC pins are not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Address Input 1 | Selects switch pair: A1=0 selects COMA/NO1A/NO2A; A1=1 selects COMB/NO1B/NO2B |
| GND | Logic Ground Reference | Reference for digital control inputs; must be tied to system ground, not floating |
| V+ | Positive Supply Rail | Bias for internal logic and switch P-channels; supports up to +15V in single-supply mode |
| NO1B | Normally Open Terminal B-Side Channel 1 | Analog input path for first switch in B group; connects to COMB when selected |
| NO1A | Normally Open Terminal A-Side Channel 1 | Analog input path for first switch in A group; connects to COMA when selected |
| V− | Negative Supply Rail | Bias for internal logic and switch N-channels; tied to GND for single-supply operation |
| EN | Global Enable Input | High enables both switch groups; low forces all channels into high-impedance off-state |
| A0 | Address Input 0 | Together with A1, selects active NO terminal per group (e.g., A1A0=00 → NO1A/NO1B) |
| NO2B | Normally Open Terminal B-Side Channel 2 | Second analog input in B group; routed to COMB when A1A0=10 or 11 |
| COMB | Common Output Terminal B Group | Shared output node for B-side switches; bidirectional signal path with rail-to-rail swing |
| COMA | Common Output Terminal A Group | Shared output node for A-side switches; electrically isolated from COMB |
| NO2A | Normally Open Terminal A-Side Channel 2 | Second analog input in A group; routed to COMA when A1A0=01 or 11 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from V− to V+ without clipping - essential for ±5V sensor outputs and unipolar 0–3.3V MCU interfaces |
| Guaranteed flat on-resistance | <10Ω variation over full signal range - maintains linearity in precision gain-setting and calibration paths |
| Low power consumption | <300µW typical - extends battery life in handheld test gear and portable medical monitors |
| Electrostatic discharge protection | >2000V HBM - reduces need for external TVS diodes in field-deployable equipment |
| Break-before-make switching | <40ns guaranteed tOPEN - prevents momentary shorting between signal sources during channel change |

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 (±15V), but no break-before-make guarantee | Preferred for high-voltage industrial PLC I/O modules where leakage & speed are secondary | Choose ADG1419BRUZ only if ±15V operation or lower RON at high temperature is required; MAX4519ESD+ remains superior for low-leakage, low-glitch S&H |
| TS5A23157DGSR | Lower voltage rating (+5.5V max), higher charge injection (12pC), but smaller 10-pin VSSOP package | Suitable for space-constrained consumer audio routing where ±5V operation suffices | Use TS5A23157DGSR only in cost-sensitive, low-voltage (<5V) designs accepting higher glitch energy; MAX4519ESD+ provides better thermal stability and leakage control |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4519ESD+ uniquely balances ultra-low charge injection, guaranteed break-before-make, and wide supply flexibility - making it optimal for precision, low-power, and mixed-voltage analog routing where signal integrity is critical.

FAQ
What is the operating temperature range for the MAX4519ESD+?
The MAX4519ESD+ is rated for –40°C to +85°C operation, confirmed by its "E" grade suffix and validated in the Absolute Maximum Ratings table. This range supports deployment in industrial environments and automotive cabin electronics where ambient temperatures exceed commercial-grade limits. The MAX4519ESD+ maintains specified on-resistance matching and leakage performance across this full span.
Does the MAX4519ESD+ support single-supply operation?
Yes, the MAX4519ESD+ supports single-supply operation from +2.7V to +15V. In this mode, V− must be connected to GND, and analog signals may swing rail-to-rail from GND to V+. Electrical characteristics including on-resistance (280Ω max at +3V), leakage, and switching times are fully specified for single-supply conditions in the datasheet's "Single +3V Supply" and "Single +5V Supply" sections.
What is the maximum allowable voltage difference between V+ and V− for the MAX4519ESD+?
The MAX4519ESD+ specifies a maximum V+ to V− differential of +17V, per the Absolute Maximum Ratings table. This allows asymmetric supply configurations such as +10V/–5V (15V total) but prohibits exceeding 17V. Exceeding this limit risks permanent damage due to internal junction breakdown, regardless of individual rail compliance with their own absolute max ratings.
How does the enable (EN) pin function on the MAX4519ESD+?
The EN pin on the MAX4519ESD+ is an active-high global enable: when EN = high (≥2.4V), both A- and B-side switch groups respond to A0/A1 address inputs; when EN = low (≤0.8V), all four channels enter high-impedance off-state regardless of address state. Enable turn-on time is ≤250ns, and turn-off time is ≤200ns, enabling precise gating of analog signal flow in synchronized acquisition systems.
Is the MAX4519ESD+ pin-compatible with other devices in the MAX4518/MAX4519 family?
No - the MAX4519ESD+ (SO-14) has a different pinout than the MAX4518 variants (also SO-14 but with distinct NOx/COM assignments), and differs physically from the QSOP-16 versions. While functional compatibility exists within the family (same logic interface, supply ranges, and switching behavior), direct PCB replacement requires layout verification. The MAX4519ESD+ pin map is unique to its dual 2-channel topology and must not be assumed interchangeable with MAX4518 footprints.
