Product details
Overview
The MAX399EGE from Maxim Integrated is a precision dual 4-channel CMOS analog multiplexer designed for bidirectional signal routing in low-voltage, high-accuracy systems. It delivers <100Ω on-resistance (typ. 85Ω), <6Ω channel-to-channel RON matching, <5pC charge injection, and rail-to-rail analog signal handling across ±3V to ±8V or +3V to +15V supplies - enabling use in battery-operated data-acquisition front-ends and military-grade communications switching.
For engineers reviewing the MAX399EGE datasheet, MAX399EGE pinout, MAX399EGE application, or MAX399EGE equivalent, this page provides verified electrical parameters, QFN-EP package layout, leakage performance at +85°C, enable timing behavior, and validated alternatives for dual 4-channel analog mux selection in precision analog signal paths.
Technical Context
The MAX399EGE implements a CMOS transmission-gate architecture with independent address decoding for two 4-channel banks (COMA/NO1A–NO4A and COMB/NO1B–NO4B), controlled by A0/A1 and EN. Its low-charge-injection design minimizes transient errors during channel switching, critical for sample-and-hold and precision ADC input conditioning.
It supports single-supply (+3V to +15V) and bipolar-supply (±3V to ±8V) operation with TTL/CMOS-compatible logic inputs, guaranteed ESD protection >2000V, and flat on-resistance (<11Ω variation) over full analog signal range - ensuring consistent gain and linearity across temperature and voltage rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 85Ω typical at VCOM = ±3.5V, +25°C - ensures minimal signal attenuation and gain error in sensor interface paths. |
| RON Matching | <6Ω max between channels - preserves relative amplitude accuracy in multi-channel calibration or differential measurement. |
| Charge Injection | <5pC - limits voltage glitch on hold capacitors, enabling sub-12-bit settling in sample-and-hold circuits. |
| Off-Leakage Current | <2.5nA at COM and NO terminals, +85°C - prevents drift in high-impedance sensor or integrator nodes. |
| Analog Signal Range | Rail-to-rail: ±4.5V (dual) or 0V to +4.5V (single) - supports full-scale operation with common op-amp output ranges. |
| Enable Turn-On Time | 200ns max (tON(EN)) - enables fast channel reconfiguration in automated test equipment scan sequences. |
| ESD Protection | >2000V HBM - ensures robustness during board handling and system integration without external protection. |
Pinout & Package
MAX399EGE is housed in a 16-pin QFN-EP package (4mm × 4mm, 0.9mm height) with exposed pad connected to V+. Pin 1 is top-left corner (A0); pin numbering follows standard QFN convention counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1 | Binary address inputs | Select one of four analog channels per bank (COMA/COMB); logic-compatible with 0.8V/2.4V thresholds. |
| EN | Active-high enable | Disables all switches when low; eliminates crosstalk and leakage in standby mode. |
| COMA, COMB | Common analog I/O terminals | Bidirectional ports - serve as inputs when routing NO→COM, outputs when routing COM→NO. |
| NO1A–NO4A, NO1B–NO4B | Channel analog I/O terminals | Four independent bidirectional paths per bank; matched RON enables channel-swapping without gain mismatch. |
| V+, V- | Supply rails | Support ±3V to ±8V bipolar or +3V to +15V single supply; V- tied to GND in single-supply mode. |
| GND | Reference ground | Logic and analog reference node; separate from power supply return in mixed-signal layouts. |
| EP (Pin 16) | Exposed thermal pad | Must be soldered to V+ plane for thermal dissipation and EMI reduction; not electrically isolated. |
Key Features
| Feature | Design Value |
|---|---|
| Precision RON flatness | <11Ω variation over full analog signal range - maintains consistent channel gain across ±4.5V input swing. |
| Dual-bank independent control | Separate COMA/COMB and NOx-A/NOx-B routing - enables simultaneous or staggered switching in dual-path systems. |
| Low-power operation | <300µW quiescent power - suitable for always-on monitoring nodes in portable and remote sensing devices. |
| Pin compatibility | Drop-in replacement for DG409 and DG509A - allows legacy design upgrades without PCB revision. |
| Rail-to-rail signal handling | Operates with inputs extending to V+ and V− - eliminates level-shifting needs in ±5V or +5V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG409BRUZ | Higher RON (100Ω typ), no exposed pad, SOIC-16 only; 12-bit charge injection spec (vs. MAX399EGE's 5pC). | Lower cost in industrial temp range (−40°C to +85°C), but lacks QFN thermal performance for high-density layouts. | Prefer ADG409BRUZ for cost-sensitive, non-thermal-constrained SOIC designs where 100Ω RON is acceptable. |
| TMUX1309RTER | Lower RON (4.5Ω typ), 1.8V–5.5V supply only, no bipolar support; 0.5pC charge injection. | Optimized for modern low-voltage microcontroller I/O, not legacy ±5V or high-voltage signal routing. | Choose TMUX1309RTER only for new 3.3V-only designs requiring ultra-low RON and charge injection - not for drop-in replacement. |
Compared with ADG409BRUZ and TMUX1309RTER, the MAX399EGE uniquely balances bipolar/single-supply flexibility, QFN thermal performance, and sub-5pC charge injection - making it the only option supporting military radio and HUD applications requiring both wide voltage range and high-temperature leakage stability.

FAQ
What is the operating temperature range of the MAX399EGE?
The MAX399EGE is rated for −40°C to +85°C ambient operation, validated across all key parameters including on-resistance matching, off-leakage current, and enable timing. This extended temperature grade makes it suitable for deployment in automotive under-hood modules, military radios, and outdoor industrial sensors where thermal stability is critical. The 'E' suffix explicitly denotes this industrial/military temperature range.
Does the MAX399EGE support single-supply operation?
Yes, the MAX399EGE operates from a single +3V to +15V supply. When using single-supply mode, V− must be connected to GND. The device maintains rail-to-rail analog signal handling (e.g., 0V to +4.5V with +5V supply) and retains TTL/CMOS logic compatibility. Performance metrics such as RON, leakage, and switching speed are fully specified across this range in the datasheet.
How is the exposed pad (EP) on the MAX399EGE QFN package used?
The exposed pad (Pin 16) on the MAX399EGE QFN package must be soldered directly to the V+ power plane on the PCB. It serves as both a thermal dissipation path and a low-inductance supply connection - not a ground or signal node. Leaving it floating or connecting it to GND violates the absolute maximum ratings and risks thermal runaway or ESD failure. The datasheet explicitly states "Connect EP to V+".
Is the MAX399EGE pin-compatible with the DG409?
Yes, the MAX399EGE is pin-compatible with the industry-standard DG409 in QFN, QSOP, and SO packages. Pin functions (A0, A1, EN, COMA, COMB, NO1A–NO4A, NO1B–NO4B, V+, V−, GND) align exactly, and logic thresholds (0.8V/2.4V) match. This allows direct substitution in existing DG409-based designs without layout changes - provided the exposed pad is correctly routed to V+.
What is the maximum analog signal voltage the MAX399EGE can handle?
The MAX399EGE supports analog signals from V− to V+ - i.e., rail-to-rail operation. With ±5V supplies, the full range is −5V to +5V; with +5V single supply (V− = GND), it is 0V to +5V. Absolute maximum ratings limit V+ to +17V and V− to −17V, but usable analog swing is constrained by supply rails. Exceeding V+ or V− clamps signals via internal diodes and risks damage if current exceeds 30mA.
