Product details
Overview
The MAX399CPE from Maxim Integrated is a dual 4-channel precision 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 +3V to +15V single or ±3V to ±8V dual supplies - enabling use in battery-powered data-acquisition front-ends.
For engineers reviewing the MAX399CPE datasheet, MAX399CPE pinout, MAX399CPE application, or MAX399CPE equivalent, key selection criteria include guaranteed on-resistance flatness (<11Ω), sub-250ns transition time, NO/COM off-leakage <2.5nA at +85°C, TTL/CMOS logic compatibility, and pin compatibility with DG409/DG509A for drop-in replacement in legacy designs.
Technical Context
The MAX399CPE implements two independent 4:1 analog multiplexers (COMA/NO1A–NO4A and COMB/NO1B–NO4B) controlled by 2-bit address inputs (A0, A1) and a shared enable (EN). Its silicon-gate CMOS process ensures low charge injection (<5pC) and ESD robustness (>2000V), critical for sample-and-hold integrity and system reliability.
It supports unbalanced supply configurations (e.g., +10V/–5V), maintains rail-to-rail signal swing, and guarantees flat on-resistance over the full analog range - enabling precise gain/offset matching across channels in instrumentation-grade signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 60Ω typical (max 100Ω at +25°C); ensures minimal signal attenuation and gain error in precision amplification paths. |
| RON Matching | <6Ω between channels; enables accurate differential or ratiometric measurements without per-channel calibration. |
| Charge Injection | <5pC; limits voltage glitch on sample capacitors, preserving accuracy in ADC input stages and sample-and-hold circuits. |
| Off-Leakage Current | <2.5nA at +85°C (COM/NO); prevents signal drift in high-impedance sensor interfaces and long-duration hold modes. |
| Transition Time | <250ns; supports multiplexing of signals up to ~1.5MHz without significant settling distortion. |
| Analog Signal Range | ±4.5V with ±5V supplies; allows full utilization of 12-bit+ ADC dynamic range without external level-shifting. |
| Supply Range | +3V to +15V single or ±3V to ±8V dual; enables direct integration into 3.3V, 5V, and ±5V mixed-signal systems. |
Pinout & Package
MAX399CPE is supplied in a 16-pin plastic DIP package (P16-1), with pins arranged in dual-in-line format and standard 0.3-inch body width. Pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 Address Inputs | Selects active channel (0–3) for each 4:1 mux; TTL/CMOS compatible with 0.8V/2.4V thresholds. |
| 2 | EN Enable | High-active control: disables all switches when low, reducing leakage and power in standby. |
| 3 | V− | Negative supply rail; required for bipolar operation; connect to GND for single-supply mode. |
| 4–7 | NO1A–NO4A | Input/output terminals for first 4:1 mux; bidirectional, matched RON, low crosstalk. |
| 8, 9 | COMA, COMB | Common analog I/O nodes for respective 4:1 sections; support rail-to-rail signal routing. |
| 10–13 | NO1B–NO4B | Input/output terminals for second 4:1 mux; electrically isolated from NO1A–NO4A section. |
| 14 | V+ | Positive supply rail; sets upper analog voltage limit and powers internal logic and switch drivers. |
| 15 | GND | Ground reference for logic inputs, enable, and substrate bias; must be low-impedance for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 architecture | Enables simultaneous routing of two separate analog signal streams without crosstalk or timing interaction. |
| Guaranteed RON flatness <11Ω | Maintains consistent gain and linearity across full analog input range, critical for precision transducer interfaces. |
| ESD protection >2000V | Eliminates need for external protection diodes in board-level ESD-prone environments (e.g., test equipment front panels). |
| Pin-compatible with DG409/DG509A | Allows direct replacement in existing designs using industry-standard footprint and logic interface. |
| Rail-to-rail signal handling | Supports full-scale analog signals from V− to V+ without clipping, maximizing dynamic range in single-supply systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX399CEE | Same electrical specs; QSOP-16 package (5.3mm × 10.2mm) vs. DIP-16 (19.1mm × 6.6mm); no exposed pad. | Better suited for space-constrained PCBs; requires re-layout due to different footprint and thermal profile. | Select MAX399CEE for surface-mount production; retain MAX399CPE for through-hole prototyping or legacy DIP sockets. |
| ADG409BNZ | 44Ω typical RON, 10nA max off-leakage at +85°C, 350ns transition time; SOIC-16 package; no EN pin. | Lacks enable control and has higher leakage; suitable only where channel disable is not required and slower switching is acceptable. | Choose ADG409BNZ only if board area is critical and enable functionality is implemented externally; verify leakage impact on hold-time accuracy. |
Compared with MAX399CPE, MAX399CEE offers identical performance in a smaller surface-mount package but requires PCB redesign, while ADG409BNZ trades enable functionality and leakage performance for slightly lower on-resistance - making MAX399CPE the optimal choice for through-hole, enable-controlled, low-drift precision multiplexing.

FAQ
What supply voltages does the MAX399CPE support?
The MAX399CPE operates from a single +3V to +15V supply (with V− tied to GND) or bipolar ±3V to ±8V supplies. At ±5V, it supports ±4.5V analog signal swing; at +5V single supply, it handles 0V to +4.5V. Supply sequencing (V+ first, then V−, then logic) is recommended to avoid latch-up. The MAX399CPE datasheet specifies absolute maximum ratings up to ±17V across V+ and V−.
Is the MAX399CPE pin-compatible with the DG409?
Yes, the MAX399CPE is explicitly pin-compatible with the DG409 and DG509A, sharing identical pin assignments for A0, A1, EN, COMA, COMB, NO1A–NO4A, NO1B–NO4B, V+, V−, and GND. This allows direct replacement in existing designs without PCB modification, provided the temperature range (+0°C to +70°C for MAX399CPE) and supply conditions match system requirements.
What is the maximum analog signal frequency supported by the MAX399CPE?
The MAX399CPE supports analog signals up to approximately 1.5MHz, based on its <250ns transition time and <11Ω on-resistance flatness. For high-fidelity video or RF applications, bandwidth is further limited by off-isolation (–75dB) and crosstalk (–92dB). At 1MHz, typical COM off-capacitance is 40pF and NO off-capacitance is 8pF - critical parameters for calculating RC roll-off in high-speed routing paths using the MAX399CPE.
How does charge injection affect sample-and-hold performance with the MAX399CPE?
With guaranteed charge injection <5pC, the MAX399CPE introduces ≤1.25mV error on a 4nF hold capacitor - well within 12-bit (1.22mV) and acceptable for 14-bit (0.3mV) systems at moderate sampling rates. This value is measured at VCOM = ±4.5V, V+ = 5.5V, V− = –5.5V. Lower supply voltages reduce charge injection further (e.g., <1pC at +3V), enhancing accuracy in ultra-low-power MAX399CPE implementations.
Does the MAX399CPE require external protection diodes for overvoltage?
No - the MAX399CPE includes internal protection diodes and is rated for >2000V HBM ESD. External diodes are unnecessary unless operating beyond absolute maximum ratings (e.g., transient spikes >±17V across V+/V−). Per Maxim's guidance, adding external diodes reduces analog signal range by one diode drop and is discouraged for single-supply use. The MAX399CPE's robust internal structure eliminates this design overhead in compliant systems.
