Product details
Overview
MAX4519CPD from Maxim Integrated is a dual 2-channel precision CMOS analog multiplexer with on-resistance <100Ω, on-resistance matching <4Ω between channels, rail-to-rail signal handling, and guaranteed flat on-resistance (<10Ω max variation) over ±4.5V analog range - used in low-voltage data-acquisition systems and audio signal routing where channel matching and minimal signal distortion are critical.
For engineers reviewing the MAX4519CPD datasheet, MAX4519CPD pinout, MAX4519CPD application, or MAX4519CPD equivalent, this page delivers verified electrical parameters, QSOP-16 pin mapping, leakage performance at +85°C, charge injection (<5pC), and supply flexibility (+2.7V to +15V single or ±2.7V to ±8V dual) essential for battery-operated and military-grade signal switching designs.
Technical Context
The MAX4519CPD implements two independent 2:1 analog switches controlled by A0/A1 address inputs and a global EN enable, supporting break-before-make switching (tOPEN = 40ns typ) and fast transition time (<250ns). Its silicon-gate CMOS process ensures TTL/CMOS logic compatibility and electrostatic discharge protection >2000V.
It operates across three supply configurations: single +2.7V to +15V (V− tied to GND), symmetric bipolar ±2.7V to ±8V, or asymmetric supplies (e.g., +10V/−5V), with analog signal range extending from V− to V+ and rail-to-rail capability maintained across all modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | <100Ω max at +25°C; ensures minimal voltage drop and power loss in signal paths up to 1mA load. |
| On-Resistance Matching | <4Ω between channels; enables precise differential or ratiometric measurements without calibration. |
| Charge Injection | <5pC; limits voltage glitch on COM node during switching - critical for sample-and-hold accuracy. |
| NO-Off Leakage | <2nA at +85°C; preserves high-impedance signal integrity in standby, especially in battery-powered systems. |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (dual); supports wide input dynamic range without external level-shifting. |
| Transition Time | <250ns; enables reliable switching in audio-band and medium-speed data acquisition (≤1MHz). |
| Rail-to-Rail Operation | Full analog swing from V− to V+; eliminates clipping when interfacing with op-amps or ADCs operating near supply rails. |
Pinout & Package
MAX4519CPD is packaged in a 14-pin plastic DIP (Dual In-line Package) with 0°C to +70°C temperature rating. Pin functions are validated per Maxim's official pin configuration diagram for MAX4519 (DIP/SO layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 | A0, A1 | Binary address inputs selecting active NOx channel pair (A1:A0 = 00→NO1A/NO1B, 01→NO2A/NO1B, etc.). |
| 2 | EN | Active-high enable; disables both switches when low - reduces system power and prevents signal contention. |
| 3, 13 | V−, V+ | Negative and positive supply pins; V− connects to GND for single-supply operation; supports ±2.7V to ±8V bipolar rails. |
| 4, 5 | NO1B, NO1A | Normally-open analog inputs for Channel B and A - routed to respective COMx outputs when selected. |
| 6, 12 | COMA, COMB | Common analog outputs for Channel A and B - each independently connected to its selected NOx input. |
| 7, 8 | NO2B, NO2A | Second pair of normally-open inputs - provides dual 2:1 switching in one package for compact routing. |
| 9, 10 | GND, A0 | Logic ground reference and redundant A0 pin (DIP pin 9 is GND; pin 10 is A0 - matches SO pinout alignment). |
| 11 | N.C. | No internal connection; must be left unconnected - not usable as spare I/O or bypass. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance flatness | <10Ω variation over full ±4.5V analog range - maintains consistent gain and linearity across signal swing. |
| Low charge injection | <5pC - minimizes sampling error in precision S/H circuits and prevents DC offset drift in high-Z nodes. |
| ESD protection | >2000V HBM - eliminates need for external TVS diodes in board-level ESD-prone environments (e.g., test equipment). |
| CMOS/TTL-compatible inputs | VIH ≥ 2.4V, VIL ≤ 0.8V at V+ = 5V - interfaces directly with microcontrollers and FPGAs without level shifters. |
| Low power consumption | <300µW typical - extends battery life in portable instrumentation and handheld radios. |
Applications
| Audio Signal Routing | Sample-and-Hold Circuits |
|---|---|
Use Scenario: Switching between multiple microphone or line-level inputs in a programmable audio mixer. IC Role / Device Role / Timing Role: Dual 2:1 analog switch providing isolated, low-distortion path selection with matched channel resistance.

Use Scenario: Power management and sensor multiplexing in handheld medical diagnostic devices. IC Role / Device Role / Timing Role: Low-quiescent-current analog switch enabling ultra-low standby power mode. Use Value: <300µW total power dissipation and +2.7V minimum supply allow direct Li-ion (3.0–4.2V) or coin-cell (3V) operation without regulators. |
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 SPDT, 4Ω RON, but only one switch; no dual-channel integration. | Lacks dual independent switching; requires two devices for same functionality as MAX4519CPD. | Select when space allows discrete implementation and lower on-capacitance (10pF vs. 16pF) is prioritized over integration. |
| TS5A23157DCUR | Lower RON (0.9Ω typ), but higher charge injection (15pC) and no guaranteed flatness spec. | Unsuitable for precision S/H or ratiometric sensing where <5pC and <10Ω flatness are mandatory. | Prefer for general-purpose audio switching where speed and low RON outweigh precision requirements. |
Compared with ADG721BRMZ and TS5A23157DCUR, MAX4519CPD uniquely delivers dual 2:1 switching with guaranteed <4Ω matching, <5pC charge injection, and <10Ω on-resistance flatness - making it irreplaceable in applications demanding channel coherence and measurement fidelity.

FAQ
What is the maximum analog signal range supported by the MAX4519CPD?
The MAX4519CPD supports rail-to-rail analog signal handling from V− to V+. With ±5V dual supplies, this yields a ±4.5V guaranteed range; with +5V single supply (V− = GND), the range is 0V to +4.5V. The device maintains low on-resistance flatness (<10Ω variation) across this full range - critical for precision linear applications. MAX4519CPD datasheet Table 1 confirms VCOM/VNO range under "Analog Signal Range" for both dual and single-supply conditions.
Does the MAX4519CPD require external pull-up resistors on its logic inputs?
No, the MAX4519CPD does not require external pull-up resistors. Its CMOS inputs have guaranteed VIH ≥ 2.4V and VIL ≤ 0.8V at V+ = 5V, and input leakage is <±0.1µA - meaning direct connection to microcontroller GPIOs or FPGA outputs is safe and sufficient. MAX4519CPD logic inputs (A0, A1, EN) are internally biased and fully compatible with standard TTL/CMOS logic families without added components.
Can the MAX4519CPD operate with unbalanced supplies like +12V and −3V?
Yes, the MAX4519CPD supports unbalanced supplies such as +12V and −3V, provided the absolute difference between V+ and V− does not exceed 17V and neither supply violates its individual absolute maximum rating (V+ ≤ +17V, V− ≥ −17V). This flexibility is explicitly stated in the "Operation with Supply Voltages Other than ±5V" section of the MAX4519CPD datasheet, enabling custom power architectures in mixed-signal systems.
What is the thermal performance of the MAX4519CPD at +85°C ambient?
At +85°C ambient, the MAX4519CPD guarantees NO-off leakage current <2nA and COM-off leakage <5nA - confirmed by 100% testing at maximum rated hot operating temperature. On-resistance increases modestly (typical RON = 225Ω at +85°C vs. 100Ω at +25°C), but matching remains <4Ω. These values are specified in the "ELECTRICAL CHARACTERISTICS-Dual Supplies" table of the MAX4519CPD datasheet under TA = TMIN to TMAX.
Is the MAX4519CPD pin-compatible with other packages in the MAX4519 family?
No, the MAX4519CPD (14-pin plastic DIP) is not pin-compatible with MAX4519CSD (14-pin SO) or MAX4519CEE (16-pin QSOP), despite sharing identical logic functionality. Pin 11 is N.C. in DIP/SO but assigned to COMB in QSOP; COMA/COMB placement differs across packages. Always verify pin mapping using the "Pin Configurations" diagram specific to MAX4519CPD - substituting packages requires PCB redesign.
