Product details
Overview
The MAX398EEE+ from Maxim Integrated is a precision 8-channel CMOS analog multiplexer designed for low-distortion signal routing in precision data-acquisition and test 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 or 0–4.5V), and operates from single +3V to +15V or bipolar ±3V to ±8V supplies - enabling use in battery-powered instrumentation and military-grade guidance systems.
For engineers reviewing the MAX398EEE+ datasheet, MAX398EEE+ pinout, MAX398EEE+ application, or MAX398EEE+ equivalent, key selection criteria include guaranteed RON flatness (<11Ω), sub-250ns transition time, NO/COM off-leakage <2.5nA at +85°C, and pin compatibility with DG408/DG508A - critical for legacy system upgrades and high-reliability signal switching.
Technical Context
The MAX398EEE+ implements an 8:1 bidirectional analog switch architecture with three address lines (A0–A2) and enable-controlled channel selection. Its silicon-gate CMOS process ensures TTL/CMOS logic compatibility, low input loading, and ESD protection >2000V.
All channels share a common COM terminal and exhibit matched on-resistance over full analog signal range (±4.5V dual supply or 0–4.5V single supply), with leakage performance fully tested at +85°C and guaranteed by correlation at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 60Ω typ., ≤100Ω max. - enables low insertion loss and minimal gain error in precision amplifier front-ends. |
| RON matching | <6Ω between channels - ensures consistent gain and offset across multiplexed sensor inputs. |
| Charge injection | <5pC - limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy. |
| Off-leakage (NO/COM) | <2.5nA at +85°C - maintains signal integrity in high-impedance sensor interfaces over temperature. |
| Transition time | <250ns - supports ≥2MHz multiplexed sampling without inter-channel settling penalty. |
| Analog signal range | ±4.5V (dual) or 0–4.5V (single) - accommodates industrial sensor outputs and audio line-level signals. |
| Supply range | +3V to +15V single or ±3V to ±8V bipolar - allows direct integration into mixed-voltage systems without level-shifting. |
Pinout & Package
MAX398EEE+ is housed in a 16-pin QSOP package (E16-1), 0.150" wide, with exposed pad not present (QSOP variant). Pin 1 is A0; pin 2 is EN; pins 4–7 and 9–12 are NO1–NO8 analog inputs; pin 8 is COM; pin 13 is V+; pin 14 is GND; pin 15 is A1; pin 16 is A2.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | A0, A1, A2 | 3-bit binary address inputs selecting one of eight NOx channels to connect to COM. |
| 2 | EN | Active-high enable: disables all switches when low, preventing unintended channel conduction. |
| 3 | V− | Negative supply rail (bipolar mode) or ground reference (single-supply mode). |
| 4–7, 9–12 | NO1–NO8 | Bidirectional analog input terminals - accept or source signals up to ±4.5V or 0–4.5V. |
| 8 | COM | Common bidirectional analog port - connects to selected NOx channel when enabled. |
| 13 | V+ | Positive supply rail - sets upper analog voltage limit and powers internal logic. |
| 14 | GND | Logic and analog reference ground - must be low-impedance for noise-sensitive applications. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with DG408/DG508A | Direct drop-in replacement in existing layouts - eliminates PCB redesign for legacy system refresh. |
| Guaranteed RON flatness <11Ω | Minimizes THD and gain nonlinearity across full analog signal swing - essential for audio and precision measurement. |
| Rail-to-rail signal handling | Supports full-scale operation from V− to V+ without clipping - preserves dynamic range in low-voltage systems. |
| ESD protection >2000V | Withstands HBM ESD events without latch-up or parametric shift - improves manufacturing yield and field reliability. |
| Low power consumption <300µW | Enables always-on signal monitoring in portable and remote-sensor applications with minimal thermal impact. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel, 100Ω RON, but no guaranteed RON matching spec; higher charge injection (15pC); operates only on ±5V or +5V. | Lacks guaranteed matching and low-temperature leakage specs - less suitable for precision metrology or extended-temp military use. | Prefer MAX398EEE+ where channel uniformity, low-temperature leakage, or wider supply range is required. |
| TS5A23157DGSR | 2-channel, 0.9Ω RON, but only dual configuration; no A2 address line; max supply +5.5V; not rated for -40°C to +85°C. | Not functionally equivalent - insufficient channel count and temperature rating for MAX398EEE+ use cases. | Select MAX398EEE+ when 8-channel, industrial temp grade, and proven leakage performance are mandatory. |
Compared with ADG408BRZ and TS5A23157DGSR, the MAX398EEE+ uniquely combines 8-channel count, guaranteed RON matching, -40°C to +85°C qualification, and dual/single supply flexibility - making it irreplaceable in high-fidelity, wide-temperature, multi-sensor systems.

FAQ
What is the operating temperature range for the MAX398EEE+?
The MAX398EEE+ is specified for operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and validated by leakage current testing at +85°C. All electrical characteristics - including RON, leakage, and switching time - are guaranteed across this full range, making the MAX398EEE+ suitable for deployment in outdoor, vehicular, and military platforms where ambient conditions vary widely.
Is the MAX398EEE+ pin-compatible with the DG408?
Yes, the MAX398EEE+ is explicitly stated as pin compatible with the industry-standard DG408 and DG508A. Pin assignments for address lines (A0–A2), enable (EN), COM, NO1–NO8, V+, V−, and GND match identically in the 16-pin QSOP package. This allows direct substitution without layout changes, provided supply voltages and signal levels remain within MAX398EEE+ specifications.
What is the maximum analog signal range supported by the MAX398EEE+?
The MAX398EEE+ supports an analog signal range of ±4.5V when operated from bipolar ±5V supplies, or 0V to +4.5V when operated from a single +5V supply. The device maintains rail-to-rail signal handling - meaning signals can swing from V− to V+ without clipping - and this range is guaranteed across the full -40°C to +85°C temperature range per the Electrical Characteristics tables.
Does the MAX398EEE+ require external protection diodes for overvoltage?
No, external protection diodes are not required for normal operation within absolute maximum ratings. The MAX398EEE+ includes internal protection diodes on all analog and supply pins. However, if supply sequencing cannot be controlled (e.g., V− powered before V+), external series diodes may be added - though this reduces the effective analog signal range by one diode drop and is not recommended for single-supply configurations.
How does charge injection affect performance in sample-and-hold circuits using the MAX398EEE+?
Charge injection in the MAX398EEE+ is guaranteed ≤5pC, which directly determines the voltage glitch imposed on the hold capacitor during channel switching. For example, with a 10nF hold capacitor, the resulting error is ≤0.5mV - enabling accurate DC-coupled acquisition in 12-bit systems. This spec is measured and guaranteed at +25°C and correlated for operation across the full -40°C to +85°C range.
