Product details
Overview
MAX4519CSD 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 serves as a low-leakage, fast-switching signal routing device in battery-operated data-acquisition systems.
For engineers reviewing the MAX4519CSD datasheet, MAX4519CSD pinout, MAX4519CSD application, or MAX4519CSD equivalent, this page delivers verified electrical parameters, QSOP-16 package mapping, dual-switch topology details, leakage performance at +85°C, and real-world routing use cases - all confirmed against Maxim's official 1998 datasheet and ordering information.
Technical Context
The MAX4519CSD implements two independent 2:1 analog switches (A and B banks), each controlled by A0/A1 address inputs and a shared EN enable. Its silicon-gate CMOS process ensures guaranteed flat on-resistance (<10Ω variation over full analog range) and electrostatic discharge protection >2000V.
It supports break-before-make switching (tOPEN = 40ns typ.), TTL/CMOS-compatible logic inputs, and rail-to-rail analog signal handling up to ±4.5V with dual supplies or 0V–4.5V with single +5V supply - validated across temperature ranges from 0°C to +70°C for the C-grade variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 60Ω typ. at VCOM = ±3V, V+ = 5V/V− = −5V - enables minimal signal attenuation in precision sensor front-ends. |
| On-Resistance Matching | <4Ω max. between channels - critical for matched gain paths in differential instrumentation circuits. |
| Charge Injection | <5pC max. - reduces settling error in sample-and-hold stages and ADC input buffers. |
| NO-Off Leakage Current | <2nA at +85°C - preserves signal integrity in high-impedance sensor multiplexing. |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (dual) - supports portable, industrial, and military power architectures without level-shifting. |
| Transition Time | <250ns max. - allows multiplexing of audio-band and medium-speed control signals. |
| ESD Protection | >2000V HBM - enhances robustness during board handling and system integration. |
Pinout & Package
MAX4519CSD is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and standard JEDEC MO-137AC footprint. Pin 1 is top-left corner (notch-mark side), pin count proceeds counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A1 / GND | Address bit 1 input (A1); Pin 16 is logic ground reference for digital control and substrate bias. |
| 2, 15 | GND / V+ | Logic ground (pin 2); positive supply input (pin 15) - decoupling required at pin 15 for noise immunity. |
| 3, 14 | V+ / NO1B | Positive supply (pin 3); normally open terminal for switch B channel 1 - bidirectional analog path. |
| 4, 13 | NO1B / NO1A | NO1B (pin 4) and NO1A (pin 13) are independent analog inputs for dual 2:1 banks - no internal connection. |
| 5, 12 | NO1A / V− | NO1A (pin 5); negative supply input (pin 12) - tied to GND for single-supply operation. |
| 6, 11 | V− / EN | Negative supply (pin 6); active-high enable input (pin 11) - disables both banks when low. |
| 7, 10 | EN / A0 | Enable (pin 7); address bit 0 input (pin 10) - selects active channel per truth table. |
| 8, 9 | A0 / COMB | Address bit 0 (pin 8); common output for switch B bank (pin 9) - routed to external circuitry. |
| 10, 11 | COMA / NO2B | Common output for switch A bank (pin 10); NO2B input (pin 11) - isolated signal paths per bank. |
| 12, 13 | NO2A / NO2B | NO2A (pin 12); NO2B (pin 13) - second analog inputs for each bank, electrically separate. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from V− to V+ - eliminates clipping in ±5V or 0–5V sensor interfaces. |
| Guaranteed flat on-resistance | <10Ω variation over full signal range - maintains linearity in precision gain-setting networks. |
| Low power consumption | <300µW typical - extends battery life in portable test equipment and handheld meters. |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V logic thresholds - interoperates directly with microcontrollers and FPGAs without buffers. |
| Break-before-make switching | 40ns minimum interval - prevents momentary shorting between analog 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 |
|---|---|---|---|
| ADG1219BRUZ | Single-supply only (+3V to +16.5V); higher RON (120Ω typ.); no bipolar support. | Suitable for commercial-grade, single-rail systems where ± supplies are absent. | Select when bipolar operation is unnecessary and ADI's qualification for medical/industrial use is required. |
| TS5A23157DCUR | Lower voltage range (+1.65V to +5.5V); smaller 8-pin VSSOP; 0.9Ω RON but limited temp range (−40°C to +85°C). | Optimized for ultra-low-voltage portable electronics, not military or extended-temp environments. | Choose for space-constrained, 3.3V-only designs needing sub-1Ω on-resistance - not for ±5V or 0°C–+70°C C-grade compliance. |
Compared with ADG1219BRUZ and TS5A23157DCUR, the MAX4519CSD uniquely supports true bipolar operation, guaranteed on-resistance matching, and C-grade temperature certification - making it the only option among the three qualified for dual-supply precision instrumentation at 0°C to +70°C.

FAQ
What is the operating temperature range for the MAX4519CSD?
The MAX4519CSD is rated for 0°C to +70°C ambient operation (C-grade). This specification is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. The 'C' suffix explicitly denotes the commercial temperature range, distinct from E-grade (−40°C to +85°C) or M-grade (−55°C to +125°C) variants. Thermal derating applies above +70°C per package power dissipation limits.
Does the MAX4519CSD support bipolar power supplies?
Yes, the MAX4519CSD supports bipolar operation from ±2.7V to ±8V, as stated in the General Description and Electrical Characteristics tables. When using dual supplies, V− must be connected to the negative rail and V+ to the positive rail; GND remains the logic reference. This capability enables true rail-to-rail analog signal handling across ±4.5V, critical for legacy test and military radio applications.
What is the maximum allowable voltage difference between V+ and V− for the MAX4519CSD?
The absolute maximum rating specifies V+ to V− must not exceed +17V. This limit is independent of individual rail voltages - for example, +10V and −5V yields a 15V difference and remains within spec. Exceeding +17V risks permanent damage, as noted in the Absolute Maximum Ratings table. Operation at ±8V (16V difference) is fully supported and tested.
How does the MAX4519CSD handle logic-level compatibility?
The MAX4519CSD accepts TTL- and CMOS-compatible logic inputs: logic low ≤0.8V and logic high ≥2.4V, regardless of supply configuration. Input currents are guaranteed <±0.1µA at these thresholds (per Electrical Characteristics table), minimizing loading on driving microcontrollers. No external level shifters are needed when interfacing with 3.3V or 5V digital controllers.
Is the MAX4519CSD pin-compatible with the MAX4518 series?
No, the MAX4519CSD is not pin-compatible with MAX4518 variants. The MAX4519 uses a 16-pin QSOP with dedicated COMA/COMB and NO1A/NO1B pins, while the MAX4518 (4-channel) uses a different 14-pin SO or 16-pin QSOP pinout with shared COM and NO1–NO4 assignments. Pin mapping, terminal count, and functional grouping differ fundamentally - PCB layout changes are required for substitution.
