Product details
Overview
MAX4519EPD from Maxim Integrated is a dual 2-channel precision CMOS analog multiplexer designed for low-distortion signal routing in battery-operated and rail-to-rail systems. It delivers <100Ω on-resistance (typ. 60Ω), <4Ω channel-to-channel matching, <5pC charge injection, and operates from single +2.7V to +15V or bipolar ±2.7V to ±8V supplies - enabling use in portable data-acquisition and military radio front-ends.
For engineers reviewing the MAX4519EPD datasheet, MAX4519EPD pinout, MAX4519EPD application, or MAX4519EPD equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), NO-off leakage <2nA at +85°C, break-before-make timing (90–245ns), TTL/CMOS logic compatibility, and QSOP-16 package suitability for space-constrained mixed-signal PCBs.
Technical Context
The MAX4519EPD implements two independent 2:1 analog switches with separate COMA/COMB and NO1A/NO2A/NO1B/NO2B terminals, controlled by A0/A1 address lines and a global EN enable input. Its silicon-gate CMOS process ensures rail-to-rail analog signal handling and electrostatic discharge protection >2000V.
Switching behavior follows a break-before-make architecture (tOPEN = 90–245ns), minimizing transient glitches during channel selection. Logic inputs accept TTL/CMOS thresholds (VIL ≤ 0.8V, VIH ≥ 2.4V), and supply current remains below 10µA per rail across -40°C to +85°C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 60Ω typ., 100Ω max. - ensures minimal signal attenuation and gain error in precision sensor or audio paths. |
| On-Resistance Matching | <4Ω between channels - critical for differential signal integrity and matched filter response. |
| Charge Injection | <5pC - reduces sampling error in sample-and-hold circuits and ADC front-ends. |
| NO-Off Leakage | <2nA at +85°C - preserves accuracy in high-impedance sensor interfaces and low-power standby modes. |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (dual) - supports wide-input industrial sensors and legacy ±5V systems. |
| Transition Time | <250ns - enables fast multiplexing in automatic test equipment scanning up to ~2MHz. |
| Logic Compatibility | TTL/CMOS - simplifies interface with microcontrollers, FPGAs, and legacy digital logic without level shifters. |
Pinout & Package
MAX4519EPD is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), rated for -40°C to +85°C operation. Pin assignments are validated per Maxim's official pin configuration diagram for MAX4519 (QSOP top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting active switch pair (NO1A/COMA or NO2A/COMA, NO1B/COMB or NO2B/COMB). |
| 2, 15 | GND, V+ | Logic ground reference and positive supply rail - V+ connects substrate; GND establishes logic threshold baseline. |
| 3, 14 | V+, V- | Positive and negative analog supply pins - V- tied to GND for single-supply operation; defines full analog signal range. |
| 4, 5, 10, 11 | NO1A, NO1B, NO2A, NO2B | Normally-open analog inputs - each connects to its respective COM terminal only when selected via A0/A1/EN. |
| 6, 9 | EN, COMA | Global enable (active-high) and common output for Switch A - EN must be high for any A-side switching. |
| 7, 8, 12, 13 | COMB, NO2B, NO1B, A0 | Common output for Switch B and associated inputs - COMB and NOx-B form second independent 2:1 mux path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V- to V+ without clipping - essential for full-scale sensor output capture in low-voltage systems. |
| Guaranteed flat RON | <10Ω variation over full signal range - maintains consistent gain and linearity across ±4.5V inputs. |
| Low power consumption | <300µW typical - extends battery life in portable instrumentation and handheld test gear. |
| ESD protection | >2000V HBM - improves manufacturing yield and field reliability in unshielded environments like PBX panels. |
| Break-before-make switching | 90–245ns interval prevents momentary short-circuits during channel transitions - protects sensitive downstream circuitry. |
Applications
| Sample-and-Hold Circuits | Automatic Test Equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1219BRUZ | Single-supply only (+3V to +16.5V); higher RON (120Ω max); no bipolar support. | Suitable for commercial-grade industrial PLC I/O modules but not military or dual-rail systems. | Select when bipolar operation is unnecessary and board space permits SOIC-16 instead of QSOP-16. |
| TS5A23157DGSR | Lower voltage range (+1.65V to +5.5V); faster tTRANS (11ns); higher leakage (25nA @ +85°C). | Better for high-speed USB/audio switching in consumer devices; insufficient for ±5V sensor front-ends. | Prefer for battery-powered audio routing where speed outweighs leakage and supply flexibility. |
Compared with ADG1219BRUZ and TS5A23157DGSR, the MAX4519EPD uniquely supports both single- and bipolar supplies while maintaining sub-2nA leakage and <4Ω matching - making it the only option among the three qualified for precision, wide-temperature, dual-rail data acquisition.

FAQ
What is the maximum analog signal range supported by the MAX4519EPD?
The MAX4519EPD supports an analog signal range from V− to V+, which spans ±2.7V to ±8V under bipolar operation or 0V to +2.7V to +15V under single-supply conditions. At ±5V supplies, the full-range signal handling is ±4.5V, verified per electrical characteristics tables in the datasheet. This range is maintained without distortion due to rail-to-rail design and flat on-resistance.
Does the MAX4519EPD require external pull-up resistors on its logic inputs?
No, the MAX4519EPD does not require external pull-up resistors on A0, A1, or EN inputs. Its CMOS inputs exhibit low leakage (<0.1µA) and are fully compatible with TTL/CMOS logic levels (VIL ≤ 0.8V, VIH ≥ 2.4V) across the full supply range. Internal input structure ensures reliable switching without external biasing, simplifying FPGA or microcontroller interface design.
Can the MAX4519EPD be used in a single-supply configuration with V− grounded?
Yes, the MAX4519EPD supports single-supply operation with V− connected to GND. In this mode, the analog signal range becomes 0V to V+, supporting inputs from 0V to +2.7V up to +15V. The device retains all key specs including <100Ω RON, <5pC charge injection, and <2nA NO-off leakage at +85°C - confirmed in the "Single +5V Supply" and "Single +3V Supply" electrical characteristic tables.
What is the thermal performance rating of the MAX4519EPD package?
The MAX4519EPD is specified for operation from -40°C to +85°C and packaged in a 16-pin QSOP with a thermal resistance θJA of 9.52°C/W (derating 9.52mW/°C above +70°C). Its guaranteed parameters - including on-resistance matching, leakage, and switching times - are validated across this full industrial temperature range, ensuring reliability in embedded control and outdoor instrumentation.
How does the break-before-make timing affect system-level design with the MAX4519EPD?
The MAX4519EPD guarantees a break-before-make interval (tOPEN) of 90ns to 245ns, preventing momentary shorts between channels during switching. This eliminates cross-talk and latch-up risk in high-impedance or current-sensitive circuits. Designers must ensure that downstream circuitry tolerates the resulting signal gap - typically addressed via hold capacitors in sample-and-hold stages or buffering in audio paths.
