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 analog signal handling (±4.5V or 0–4.5V), and operates from single +2.7V to +15V or bipolar ±2.7V to ±8V supplies - enabling use in portable medical sensors and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4519EEE+ datasheet, MAX4519EEE+ pinout, MAX4519EEE+ application, or MAX4519EEE+ equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), sub-2nA NO-off leakage at +85°C, break-before-make timing (90ns typ.), TTL/CMOS-compatible logic inputs, and QSOP-16 packaging for space-constrained PCB layouts.
Technical Context
The MAX4519EEE+ implements a dual independent 2:1 analog switch architecture with separate COMA/COMB and NO1A/NO2A/NO1B/NO2B terminals, controlled by A0/A1 address lines and an active-high EN enable. Its low-charge-injection design minimizes sampling error in precision sample-and-hold circuits, while matched on-resistance ensures consistent gain across channels in multi-path signal conditioning.
It supports both unipolar and bipolar operation without external level-shifting: V− can be tied to GND for single-supply use, or biased negatively for true bipolar signal switching. The device's electrostatic discharge protection (>2000V HBM) and guaranteed leakage performance over −40°C to +85°C make it suitable for industrial control I/O modules requiring long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 60Ω typical at +25°C; ensures minimal voltage drop and gain error in sensor signal paths |
| On-Resistance Matching (∆RON) | <4Ω max between channels; critical for matched gain in differential or ratiometric measurements |
| Charge Injection (Q) | <5pC typical; limits voltage glitch and settling time in sample-and-hold and ADC driver stages |
| NO-Off Leakage Current | <2nA at +85°C; preserves accuracy in high-impedance sensor interfaces and battery-monitoring circuits |
| Supply Range | +2.7V to +15V single or ±2.7V to ±8V dual; supports direct integration with Li-ion, 5V, and ±5V system rails |
| Transition Time (tTRANS) | <250ns typical; enables fast channel switching in automatic test equipment and commutated sensor arrays |
| Logic Compatibility | TTL/CMOS input thresholds (0.8V/2.4V); eliminates need for level translators when driven by microcontrollers or FPGAs |
Pinout & Package
MAX4519EEE+ is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), optimized for automated assembly and thermal performance in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting active channel pair (A0/A1 = 00→NO1A/NO1B, 01→NO2A/NO1B, etc.) |
| 2, 15 | GND, V+ | Logic ground reference and positive supply rail; V+ powers internal logic and switch drivers |
| 3, 14 | V+, V− | Positive and negative analog supply pins; V− tied to GND enables single-supply operation |
| 4, 13 | NO1B, NO1A | Analog inputs for Channel B and A of first 2:1 mux; bidirectional signal path with rail-to-rail support |
| 5, 12 | NO2B, NO2A | Analog inputs for Channel B and A of second 2:1 mux; electrically isolated from first pair |
| 6, 11 | EN, COMB | Active-high enable controlling both muxes; COMB is common output for second mux |
| 7, 10 | A0, COMA | Shared address line and common output for first mux; COMA/COMB must be externally decoupled |
| 8, 9 | A1, N.C. | Second address bit; pin 9 is not internally connected - must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ (e.g., −4.5V to +4.5V or 0V to +4.5V), eliminating clipping in wide-dynamic-range sensor interfaces |
| Guaranteed on-resistance flatness | <10Ω variation over full signal range, ensuring stable gain and minimal THD in audio and instrumentation amplifiers |
| Break-before-make switching | 90ns minimum interval prevents momentary shorting between channels - essential for safe reconfiguration in power monitoring circuits |
| Low power consumption | <300µW typical at +5V; extends battery life in portable diagnostic devices and handheld meters |
| ESD robustness | >2000V HBM rating; reduces field failure risk in manufacturing test fixtures and unshielded industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG726BRUZ | Single-supply only (+1.8V to +5.5V); 4.5Ω RON; no bipolar support; smaller 24-TSSOP package | Suitable for ultra-low-voltage digital systems but cannot replace MAX4519EEE+ in ±5V signal chains | Select when operating exclusively from 3.3V/5V rails and board space is constrained |
| TS5A23157DGSR | Lower RON (0.9Ω typ), but higher charge injection (12pC); rated only to +85°C; no guaranteed leakage specs above +70°C | Better for high-speed audio switching, less suitable for precision DC-coupled sensor multiplexing | Prefer for cost-sensitive consumer audio where sub-picoamp leakage is non-critical |
Compared with ADG726BRUZ and TS5A23157DGSR, the MAX4519EEE+ uniquely combines bipolar supply capability, guaranteed sub-2nA leakage at +85°C, and <4Ω matching - making it the only option among the three qualified for ruggedized industrial data acquisition with calibrated accuracy requirements.

FAQ
What is the maximum analog signal range supported by the MAX4519EEE+?
The MAX4519EEE+ supports rail-to-rail analog signals from V− to V+. With bipolar ±5V supplies, this yields a ±4.5V signal range; with single +5V supply (V− = GND), it supports 0V to +4.5V. The device maintains specified on-resistance flatness and leakage performance across these ranges, as verified in the datasheet's Electrical Characteristics tables for dual- and single-supply conditions.
Does the MAX4519EEE+ require external pull-up resistors on its logic inputs?
No, the MAX4519EEE+ does not require external pull-up resistors. Its A0, A1, and EN inputs are CMOS-compatible with guaranteed logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and input leakage <±0.1µA at +25°C. Direct connection to microcontroller GPIOs or FPGA outputs is fully supported without additional biasing components.
Can the MAX4519EEE+ operate with unbalanced supplies like +12V and −5V?
Yes, the MAX4519EEE+ supports unbalanced supplies as long as the absolute voltage on V+ does not exceed +17V, V− does not go below −17V, and the total V+–V− differential remains ≤17V. The datasheet explicitly confirms operation with configurations such as +10V/−5V, and analog signal range scales accordingly - e.g., −4.5V to +11.5V in that case.
How is channel selection implemented on the MAX4519EEE+?
Channel selection on the MAX4519EEE+ uses two binary address inputs (A0, A1) and an active-high enable (EN). When EN = HIGH, A0/A1 = 00 selects NO1A/NO1B → COMA/COMB; 01 selects NO2A/NO1B; 10 selects NO1A/NO2B; 11 selects NO2A/NO2B. All combinations are defined in the Truth Table on page 11 of the datasheet, and no external decoding logic is required.
Is the MAX4519EEE+ pin-compatible with other variants in the MAX4518/MAX4519 family?
No, the MAX4519EEE+ is not pin-compatible with the MAX4518 series. While both use 16-pin QSOP packages, their pinouts differ fundamentally: MAX4518 has a single COM and four NO pins (NO1–NO4), whereas MAX4519 features dual COM (COMA/COMB) and four dedicated NO pins (NO1A/NO2A/NO1B/NO2B) arranged for independent 2:1 switching. PCB layout must match the specific variant.
