Product details
Overview
The MAX399EEE+ 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. 60Ω), <6Ω channel-to-channel RON matching, <5pC charge injection, rail-to-rail analog signal handling (±4.5V with ±5V supplies), and operates from single +3V to +15V or bipolar ±3V to ±8V supplies - enabling use in battery-powered data acquisition and military-grade guidance systems.
For engineers reviewing the MAX399EEE+ datasheet, MAX399EEE+ pinout, MAX399EEE+ application, or MAX399EEE+ equivalent, key selection criteria include guaranteed RON flatness (<11Ω), sub-250ns transition time, NO/COM off-leakage <2.5nA at +85°C, ESD protection >2000V, and pin compatibility with DG409/DG509A for drop-in upgrades in legacy test equipment and avionics interfaces.
Technical Context
The MAX399EEE+ implements a dual independent 4:1 analog mux architecture with separate COMA/COMB outputs and shared address/control logic (A0, A1, EN). Its silicon-gate CMOS process ensures low charge injection (<5pC) and tight RON matching (<6Ω), critical for sample-and-hold accuracy and multichannel sensor front-ends.
It supports both unbalanced and balanced supply configurations (e.g., +10V/–5V), retains TTL/CMOS logic compatibility across its full supply range, and guarantees rail-to-rail signal switching without degradation in leakage or on-resistance flatness over temperature (–40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Dual 4-channel (independent COMA/COMB outputs) |
| On-Resistance (RON) | 60Ω typ. (at VCOM = ±3V, V+ = +5V, V− = –5V); enables <1 LSB error in 12-bit systems with 1kΩ source impedance |
| RON Matching | <6Ω max difference between channels; ensures gain consistency across multiplexed sensor inputs |
| Charge Injection | <5pC max; limits voltage glitch on hold capacitor to <5mV with 1nF sampling cap |
| Off-Leakage Current | <2.5nA at +85°C (COM/NO); preserves accuracy in high-impedance pH or thermocouple circuits |
| Supply Range | +3V to +15V single or ±3V to ±8V dual; supports direct integration into 3.3V, 5V, and ±5V industrial rails |
| Transition Time | <250ns (V+ = +5.5V, V− = –5.5V); allows >1MHz multiplexed sampling without inter-channel skew |
Pinout & Package
MAX399EEE+ is supplied in a 16-pin QSOP package (package code E16-1), 0.150" wide, with gull-wing leads and standard JEDEC MO-137AC footprint. The exposed pad is absent - this variant uses plastic-body QSOP, not QFN-EP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting active channel (00–11) for each 4-channel bank |
| 2 | EN | Active-high enable: disables all switches when low; essential for power gating and fault isolation |
| 3 | V− | Negative supply rail input; must be connected even in single-supply mode (tie to GND) |
| 4–7 | NO1A–NO4A | Analog inputs for first 4-channel bank; bidirectional, rail-to-rail capable |
| 8, 9 | COMA, COMB | Independent common outputs for each 4-channel bank; support simultaneous dual-path routing |
| 10–13 | NO1B–NO4B | Analog inputs for second 4-channel bank; electrically isolated from NO1A–NO4A |
| 14 | V+ | Positive supply rail input; powers internal logic and switch driver stages |
| 15 | GND | Ground reference for logic inputs and substrate bias; requires low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible replacement | Direct drop-in for DG409 and DG509A in existing PCB layouts - no redesign required |
| Guaranteed RON flatness | <11Ω variation over full analog signal range (±4.5V); eliminates gain nonlinearity in precision instrumentation |
| Rail-to-rail signal handling | Switches signals from V− to V+ without clipping; supports full dynamic range of ±5V op-amp stages |
| Low power consumption | <300µW typical (I+ & I− <1µA each); extends battery life in portable ATE and handheld meters |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V logic thresholds across entire supply range; interoperable with FPGA, MCU, and ASIC control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX399ESE+ | Same electrical specs; supplied in narrow SOIC (S16-1) instead of QSOP - 0.150" vs. 0.220" width | Preferred for space-constrained PCBs where QSOP footprint is unavailable; identical thermal and electrical behavior | Select MAX399ESE+ only if board layout requires narrower package; otherwise MAX399EEE+ offers superior manufacturability in automated assembly |
| ADG409BRUZ | Higher RON (100Ω typ.), higher charge injection (12pC), no guaranteed RON matching spec; operates up to +16.5V but lacks ±3V min spec | Suitable for general-purpose routing where precision matching is non-critical; not recommended for sample-and-hold or metrology | Choose ADG409BRUZ only for cost-sensitive, non-precision applications; MAX399EEE+ remains superior for leakage- and matching-critical designs |
Compared with MAX399ESE+, the MAX399EEE+ offers identical performance in a more widely supported QSOP package; versus ADG409BRUZ, it delivers tighter RON matching, lower charge injection, and guaranteed leakage specs - making it the preferred choice for high-fidelity signal routing in military, test, and portable instrumentation.

FAQ
What is the operating temperature range of the MAX399EEE+?
The MAX399EEE+ is rated for operation from –40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and validated across all key parameters including on-resistance, leakage current, and switching speed - making the MAX399EEE+ suitable for deployment in outdoor military radios and industrial data loggers without derating.
Does the MAX399EEE+ support single-supply operation?
Yes, the MAX399EEE+ supports single-supply operation from +3V to +15V. When used in single-supply mode, V− must be connected to GND. Electrical characteristics such as on-resistance (280Ω typ. at +5V) and transition time (275ns typ.) are fully specified in the Single +5V and Single +3V sections of the datasheet - confirming reliable functionality without dual rails.
Is the MAX399EEE+ pin-compatible with the DG409?
Yes, the MAX399EEE+ is explicitly stated as pin compatible with the industry-standard DG409 and DG509A. Pin mapping (A0/A1/EN/V+/V−/GND/COMA/COMB/NO1A–NO4A/NO1B–NO4B) matches exactly per the Pin Description table - enabling direct replacement in legacy designs without PCB modification or firmware changes.
What is the maximum analog signal range supported by the MAX399EEE+?
The MAX399EEE+ supports a maximum analog signal range of ±4.5V when operated with ±5V supplies, and rail-to-rail (V− to V+) under all valid supply conditions. This is guaranteed by specification in the Electrical Characteristics tables and confirmed in Typical Operating Characteristics plots - ensuring full-swing signal integrity in ±5V instrumentation amplifier interfaces.
How does the MAX399EEE+ handle charge injection in sample-and-hold circuits?
The MAX399EEE+ guarantees charge injection of less than 5pC, measured per Figure 5 and specified in the Electrical Characteristics tables. In a sample-and-hold circuit with a 1nF hold capacitor, this results in a maximum voltage glitch of 5mV - well within acceptable limits for 12-bit accuracy. This performance is validated across temperature and supply conditions, directly supporting precision data acquisition.
