Product details

Overview

MAX308EUE+ from Maxim Integrated is a precision single-ended 1-of-8 CMOS analog multiplexer with on-resistance <100Ω, on-resistance matching <5Ω between channels, and rail-to-rail signal handling up to ±20V bipolar or +30V single supply - deployed in automatic test equipment for high-fidelity signal routing across 8 input channels to a shared COM node.

For engineers reviewing the MAX308EUE+ datasheet, MAX308EUE+ pinout, MAX308EUE+ application, or MAX308EUE+ equivalent, this device is evaluated for low charge injection (<10pC), sub-250ns transition time, -40°C to +85°C operation in 16-pin TSSOP, and drop-in replacement capability for DG408/DG508A in precision sample-and-hold and military radio front-ends.

Technical Context

The MAX308EUE+ implements a monolithic CMOS switch matrix with precision decode logic controlling eight bidirectional NOx inputs to a single COM output. Its silicon-gate architecture ensures matched channel resistance and flat R_ON (≤7Ω variation over ±10V signal range) without external calibration.

It supports TTL/CMOS-compatible digital control (A0–A2, EN) and operates across wide supply rails (+5V to +30V or ±5V to ±20V), with internal ESD protection >2000V and guaranteed leakage <5nA (NO-off) at +85°C - enabling robust performance in battery-operated and harsh-environment systems.

Key Specifications

Configuration	Single-ended 1-of-8 analog multiplexer (8:1)
On-Resistance (R_ON)	<100Ω max - enables low insertion loss in signal chains with ≤0.1% gain error at 1kΩ load
R_ON Matching	<5Ω max between channels - ensures minimal crosstalk-induced gain mismatch in multi-channel acquisition
Charge Injection	<10pC - limits voltage glitch to <10mV on 1nF hold capacitors in sample-and-hold circuits
Transition Time	<250ns - supports ≥2MHz switching in automated test sequencing
Analog Signal Range	Rail-to-rail: ±20V (bipolar) or 0V to +30V (single supply) - accommodates industrial sensor outputs and audio line-level signals
NO-Off Leakage	<5nA at +85°C - preserves accuracy in high-impedance DC-coupled measurement paths

Pinout & Package

MAX308EUE+ is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed pad for thermal enhancement and standard JEDEC MO-153 compliance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	A0, A1, A2	Binary address inputs selecting one of eight NOx channels (000–111)
4–7, 9–12	NO1–NO4, NO5–NO8	Bidirectional analog inputs - electrically identical, interchangeable signal paths
8	COM	Common analog output terminal - connects selected NOx channel; bidirectional
13	V+	Positive supply rail - accepts +5V to +30V (single) or +5V to +20V (bipolar)
14	GND	Ground reference - tied to V− when using single supply
15	V−	Negative supply rail - accepts −5V to −20V (bipolar); connect to GND for single supply
16	EN	Active-high enable - disables all switches when low; reduces power consumption to <300µW

Key Features

Feature	Design Value
Rail-to-rail signal handling	Supports full-scale analog signals from V− to V+, eliminating level-shifting in ±15V systems
Guaranteed R_ON flatness	≤7Ω variation across ±10V range - maintains consistent gain in precision instrumentation amplifiers
TTL/CMOS logic compatibility	Accepts 0.8V/2.4V thresholds - interfaces directly with microcontrollers and FPGAs without level shifters
Plug-in upgrade for DG408/DG508A	Identical pinout and function - allows legacy system upgrades without PCB redesign
ESD protection >2000V	HBM-rated - withstands handling and board assembly without additional protection circuitry

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADG408BRUZ	On-resistance 100Ω (typ), R_ON match ±15Ω, no guaranteed flatness spec, −40°C to +85°C in 16-TSSOP	Higher R_ON drift vs. signal voltage; less suitable for precision DC measurement	Select when cost sensitivity outweighs R_ON flatness and charge injection requirements
DG408DN-E3	On-resistance 125Ω (max), R_ON match ±25Ω, no charge injection spec, −40°C to +85°C in 16-SOIC	Lacks guaranteed low charge injection and ESD rating; requires external protection in rugged environments	Use only in non-critical, lower-speed applications where legacy footprint compatibility is mandatory

Compared with ADG408BRUZ and DG408DN-E3, the MAX308EUE+ delivers tighter R_ON matching (<5Ω vs. ±15Ω/±25Ω), lower charge injection (<10pC vs. unspecified), and guaranteed flatness - making it preferred for precision sample-and-hold, military-grade ATE, and high-reliability heads-up displays.

FAQ

What is the maximum analog signal voltage range supported by the MAX308EUE+?

The MAX308EUE+ supports rail-to-rail analog signals from V− to V+. With ±15V dual supplies, it handles ±10V signals; with +12V single supply (V− = GND), it supports 0V to +10V. Absolute maximum ratings allow V+ up to +30V and V− down to −20V, but signal swing remains constrained by supply rails. This range is confirmed in the Electrical Characteristics tables for both dual- and single-supply conditions.

Does the MAX308EUE+ require external pull-up resistors on its address or enable pins?

No, the MAX308EUE+ features CMOS-compatible digital inputs with guaranteed VIH ≥ 2.4V and VIL ≤ 0.8V, and input leakage <±1.0µA across temperature - eliminating need for external pull-ups. The EN, A0, A1, and A2 pins interface directly with standard microcontroller GPIOs or FPGA outputs without additional biasing components.

Can the MAX308EUE+ be used with unbalanced supplies such as +24V and −5V?

Yes, the MAX308EUE+ supports unbalanced supplies per the Applications Information section. As long as V+ − V− ≤ +44V and each supply stays within its absolute maximum rating (V+ ≤ +44V referenced to V−, V− ≥ −0.3V referenced to V−), operation is valid. For +24V/−5V, the analog signal range becomes −5V to +24V, and R_ON remains specified per datasheet curves.

How does the enable pin (EN) affect power consumption of the MAX308EUE+?

When EN is low, all internal switches are disabled and supply current drops to <300µW total (I+ + I− < 0.5mA at +15V/−15V). This state eliminates signal path conduction and reduces dynamic power - critical for battery-operated systems. The enable function is fully specified across temperature and supply voltage in the Electrical Characteristics table.

Is the MAX308EUE+ pin-compatible with the MAX308CUE and MAX308EPE variants?

Yes - all MAX308 variants (including MAX308EUE+, MAX308CUE, and MAX308EPE) share identical 16-pin pinouts and logic functionality. Differences lie only in temperature grade (C = 0°C to +70°C, E = −40°C to +85°C) and package type (TSSOP vs. DIP). The MAX308EUE+ pin mapping matches Figure 1 in the datasheet exactly, confirming mechanical and electrical interchangeability within same package family.
