Product details
Overview
MAX4519CEE from Maxim Integrated is a dual 2-channel precision 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 single +2.7V to +15V or bipolar ±2.7V to ±8V supplies. It enables low-distortion signal routing in battery-operated data-acquisition systems.
For engineers reviewing the MAX4519CEE datasheet, MAX4519CEE pinout, MAX4519CEE application, or MAX4519CEE equivalent, this page delivers verified electrical parameters, QSOP-16 package mapping, dual-switch functional context, leakage performance at +85°C, and real-world routing use cases - all grounded in Maxim's official specifications.
Technical Context
The MAX4519CEE implements two independent SPDT analog switches controlled by A0/A1 address inputs and a global EN enable. Each switch features matched CMOS transmission gates with substrate tied to V+, enabling rail-to-rail analog swing and guaranteed flat on-resistance (<10Ω variation) across ±4.5V signal range under dual supply.
Its low charge injection (<5pC) and ultra-low off-leakage (NO-off <2nA at +85°C, COM-off <5nA at +85°C) are achieved via Maxim's low-voltage silicon-gate process and guarded layout, making it suitable for high-precision sample-and-hold and low-drift sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | <100Ω max at +25°C; ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching (∆RON) | <4Ω between channels; critical for differential signal integrity and ratiometric ADC applications |
| Charge Injection (Q) | <5pC; limits voltage glitch and settling time in sample-and-hold circuits using small hold capacitors |
| NO-Off Leakage Current | <2nA at +85°C; preserves accuracy in high-impedance sensor multiplexing (e.g., thermocouples, pH electrodes) |
| Supply Range | +2.7V to +15V single or ±2.7V to ±8V dual; supports direct integration into mixed-supply industrial and portable systems |
| Transition Time | <250ns; enables fast channel switching in automated test equipment without compromising throughput |
| ESD Protection | >2000V HBM; reduces need for external protection in board-level ESD-prone environments |
Pinout & Package
MAX4519CEE is housed in a 16-pin QSOP package (3.9mm × 4.9mm, 0.635mm pitch), optimized for space-constrained PCB layouts while maintaining thermal and signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | A0, A1 | Binary address inputs selecting active NOx/COMx pair; TTL/CMOS-compatible with VIH ≥ 2.4V, VIL ≤ 0.8V |
| 2, 14 | GND | Logic ground reference; must be connected to system digital ground for proper enable and address decoding |
| 3, 15 | V+ | Positive supply input; sets upper analog rail; connects to substrate for latch-up immunity |
| 4, 12 | NO1B, NO2B | Normally open terminals of Switch B; routed to COMB when selected; support bidirectional analog signals |
| 5, 11 | NO1A, NO2A | Normally open terminals of Switch A; routed to COMA when selected; electrically isolated from Switch B |
| 6, 10 | V− | Negative supply input; sets lower analog rail; connect to GND for single-supply operation |
| 7, 9 | EN | Global enable input; high = switches active, low = all channels off; controls power state and leakage path |
| 8 | COMA | Common terminal of Switch A; bidirectional I/O node with rail-to-rail voltage capability |
| 16 | COMB | Common terminal of Switch B; independent of COMA; enables true dual-channel isolation |
Key Features

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 on-resistance (120Ω typ); no bipolar support | Suitable for cost-sensitive industrial PLC I/O modules where bipolar operation is unnecessary | Choose ADG1219BRUZ if system uses only positive rails and tolerates ~20% higher RON-induced gain error |
| TS5A23157DCUR | Lower voltage rating (+1.65V to +5.5V); smaller 8-pin VSSOP; higher leakage (>10nA at +85°C) | Targeted at USB-powered portable devices with tight space constraints and moderate precision needs | Choose TS5A23157DCUR only for +3.3V-only designs where footprint reduction outweighs leakage and signal-range trade-offs |
Compared with ADG1219BRUZ and TS5A23157DCUR, the MAX4519CEE uniquely supports true bipolar operation, guarantees sub-4Ω RON matching, and delivers <2nA off-leakage at +85°C - making it the preferred choice for high-accuracy, mixed-supply, or extended-temperature applications where signal fidelity is non-negotiable.

FAQ
What is the maximum analog signal range supported by the MAX4519CEE?
The MAX4519CEE supports an analog signal range from V− to V+ - up to ±4.5V under ±5V dual supplies or 0V to +4.5V under +5V single supply. This rail-to-rail capability ensures full utilization of ADC input ranges and eliminates signal clipping in precision measurement paths. The device maintains <10Ω on-resistance flatness across this entire range, preserving linearity and minimizing harmonic distortion in the MAX4519CEE signal path.
Does the MAX4519CEE support bipolar supply operation?
Yes, the MAX4519CEE operates with bipolar supplies from ±2.7V to ±8V, enabling true symmetric analog signal handling essential for AC-coupled instrumentation and military radio front-ends. When using bipolar supplies, V− must be connected to the negative rail (not GND), and the COM/NO terminals swing fully between V− and V+. This capability is explicitly specified in the MAX4519CEE Electrical Characteristics tables and distinguishes it from single-supply-only alternatives.
What is the guaranteed on-resistance matching between channels for the MAX4519CEE?
The MAX4519CEE guarantees on-resistance matching of less than 4Ω between its two independent SPDT switches (Switch A and Switch B). This ∆RON specification is measured as RON(max) − RON(min) across temperature and supply conditions, and is critical for maintaining common-mode rejection in differential signal routing. The value is confirmed in the "ELECTRICAL CHARACTERISTICS-Dual Supplies" table of the MAX4519CEE datasheet under symbol ∆RON.
How does the MAX4519CEE minimize charge injection in sample-and-hold applications?
The MAX4519CEE minimizes charge injection to less than 5pC through optimized gate overlap design and substrate biasing (substrate tied to V+), as guaranteed by Maxim's silicon-gate process. This low Q value directly limits the voltage glitch (∆V = Q / CHOLD) introduced when switching off a channel into a typical 100pF–1nF hold capacitor - enabling sub-LSB settling in 16-bit+ data acquisition systems using the MAX4519CEE.
Is the MAX4519CEE pin-compatible with other devices in the MAX4518/MAX4519 family?
The MAX4519CEE shares the same 16-pin QSOP package and pinout as the MAX4518EEE, but differs functionally: the MAX4519CEE implements two independent 2-channel SPDT switches (COMA/COMB), whereas the MAX4518EEE is a 4-channel single-pole single-throw mux with one common (COM). Pin compatibility exists only within the same device type (e.g., MAX4519CEE ↔ MAX4519EEE), not across MAX4518/MAX4519 variants. Layout reuse requires verifying switch topology alignment in the MAX4519CEE schematic.
