Product details
Overview
MAX4519CSD+ from Maxim Integrated is a dual 2-channel precision CMOS analog multiplexer designed for low-distortion signal routing in battery-powered and rail-to-rail systems. It features <100Ω on-resistance (typ. 60Ω), <4Ω channel-to-channel matching, <5pC charge injection, ±2.7V to ±8V or +2.7V to +15V supply operation, and operates across 0°C to +70°C. It serves in audio routing, data-acquisition front-ends, and test equipment switching matrices.
For engineers reviewing the MAX4519CSD+ datasheet, MAX4519CSD+ pinout, MAX4519CSD+ application, or MAX4519CSD+ equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), NO-off leakage <2nA at +85°C, break-before-make timing (200ns typ.), TTL/CMOS logic compatibility, and QSOP-16 package suitability for high-density mixed-signal PCBs.
Technical Context
The MAX4519CSD+ implements two independent SPDT analog switches controlled by A0/A1 address lines and a global EN enable input. Its silicon-gate CMOS process ensures rail-to-rail analog signal handling (±4.5V with ±5V supplies), minimal charge injection during switching, and ESD protection >2000V - critical for reliable operation in automated test and military comms systems.
It supports both single-supply (+2.7V to +15V) and bipolar-supply (±2.7V to ±8V) configurations without external level-shifting. The device guarantees monotonic on-resistance over its full analog signal range and maintains sub-5pC charge injection across temperature - enabling precision sample-and-hold and low-error multiplexed ADC interfaces.
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 between channels; enables matched gain/attenuation in differential or ratiometric circuits |
| Charge Injection (Q) | <5pC; limits voltage glitch on hold capacitors in precision S/H applications |
| NO-Off Leakage Current | <2nA at +85°C; prevents signal crosstalk and DC offset drift in high-impedance inputs |
| Supply Range | +2.7V to +15V single or ±2.7V to ±8V dual; supports wide-input-range industrial and portable designs |
| Transition Time (tTRANS) | <250ns; enables fast channel switching in real-time ATE and commutator systems |
| Logic Compatibility | TTL/CMOS inputs with VIL ≤ 0.8V, VIH ≥ 2.4V; simplifies interface to microcontrollers and FPGAs |
Pinout & Package
MAX4519CSD+ is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and exposed pad for thermal performance. Pin 1 is A1; pins 6 and 8 are V− and EN respectively; COMA/COMB are pins 11 and 9; NO1A/NO2A/NO1B/NO2B occupy pins 4, 5, 10, and 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1 | Binary address inputs | Select active channel pair (NO1A/COMA, NO2A/COMA, NO1B/COMB, NO2B/COMB) |
| EN | Global enable input | High = switch enabled; low = all channels open-circuit; supports power-gating |
| COMA, COMB | Analog common terminals | Shared output nodes for respective 2-channel switch banks; electrically isolated |
| NO1A, NO2A, NO1B, NO2B | Normally-open analog inputs | Four independent analog inputs routed to COMA or COMB based on A0/A1 state |
| V+, V− | Supply rails | V+ accepts +2.7V to +15V; V− accepts GND (single-supply) or negative rail up to −8V |
| GND | Logic ground reference | Reference for digital control signals; must be tied to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±5V op-amp interfaces |
| Guaranteed on-resistance flatness | <10Ω variation over full signal range - preserves linearity in precision instrumentation |
| Low power consumption | <300µW quiescent - extends battery life in portable medical and handheld test gear |
| ESD protection | >2000V HBM - reduces field failure risk in unshielded assembly and deployment environments |
| Break-before-make switching | 200ns minimum interval - prevents momentary shorting between channels during reconfiguration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher RON (1.3Ω typ), wider bandwidth (170MHz), but requires ≥±4.5V dual supply; no single-supply mode | Better for high-frequency RF switching; unsuitable for +3.3V-only systems | Choose ADG1419BRUZ when bandwidth >10MHz and supply headroom allows ±4.5V+ |
| TMUX1309PWR | Lower RON (0.5Ω typ), 1.8V–5.5V single-supply only, no bipolar support; higher leakage (>10nA at +85°C) | Optimized for ultra-low-voltage portable devices; lacks military-temp or dual-supply flexibility | Choose TMUX1309PWR for cost-sensitive consumer electronics with strict 1.8V–3.3V constraints |
Compared with MAX4519CSD+, ADG1419BRUZ offers superior speed and lower resistance but sacrifices single-supply versatility, while TMUX1309PWR delivers lower voltage operation at the expense of leakage and temperature range - making MAX4519CSD+ the balanced choice for industrial and defense-grade mixed-supply systems.

FAQ
What supply configurations does the MAX4519CSD+ support?
The MAX4519CSD+ supports both single-supply operation from +2.7V to +15V (with V− tied to GND) and bipolar-supply operation from ±2.7V to ±8V. It retains full CMOS logic compatibility and specified performance across this entire range, including rail-to-rail analog signal handling up to ±4.5V with ±5V supplies. This flexibility makes MAX4519CSD+ suitable for legacy industrial systems and modern low-voltage portable designs alike.
How does the MAX4519CSD+ ensure signal integrity during channel switching?
The MAX4519CSD+ ensures signal integrity via guaranteed <5pC charge injection, <4Ω on-resistance matching between channels, and a minimum 200ns break-before-make interval. These specifications minimize voltage glitches on hold capacitors, preserve gain accuracy in ratiometric measurements, and prevent momentary shorts during reconfiguration - directly supporting precision sample-and-hold and multiplexed ADC applications where MAX4519CSD+ is commonly deployed.
Is the MAX4519CSD+ pin-compatible with other devices in the MAX4518/MAX4519 family?
Yes, the MAX4519CSD+ shares identical pinout and footprint with other MAX4519 variants in QSOP-16 packaging (e.g., MAX4519EEE, MAX4519ESD), including matching pin functions for A0, A1, EN, COMA, COMB, NO1A–NO2B, V+, V−, and GND. However, it is not pin-compatible with the MAX4518 series (4-channel), which uses different channel mapping and terminal assignments in the same QSOP-16 outline.
What is the maximum operating temperature range for the MAX4519CSD+?
The MAX4519CSD+ is rated for operation from 0°C to +70°C, per its "C" grade designation. This commercial temperature range is validated across all electrical parameters in the datasheet, including leakage current, on-resistance, and switching times. For extended temperature operation, engineers should consider the MAX4519E_ _ (−40°C to +85°C) or MAX4519MJD (−55°C to +125°C) variants - but MAX4519CSD+ itself is strictly qualified for 0°C to +70°C ambient conditions.
Does the MAX4519CSD+ require external protection circuitry for overvoltage conditions?
No, the MAX4519CSD+ incorporates internal diode clamps on all analog and digital pins, providing inherent overvoltage protection up to ±0.3V beyond V+ or V−. When operated within its absolute maximum ratings (e.g., V+ ≤ +17V, V− ≥ −17V), no external protection diodes are required. External diodes are only recommended if supply sequencing cannot be guaranteed - but doing so reduces analog signal range and is unnecessary for properly designed systems using MAX4519CSD+.
