Product details
Overview
MAX308CSE+ from Maxim Integrated is a precision single-ended 1-of-8 CMOS analog multiplexer with ≤100Ω on-resistance, <5Ω channel-to-channel on-resistance matching, and <10pC charge injection. It operates from +5V to +30V single supply or ±5V to ±20V dual supplies, supports rail-to-rail analog signal handling up to ±10V, and is used in sample-and-hold circuits and automatic test equipment.
For engineers reviewing the MAX308CSE+ datasheet, MAX308CSE+ pinout, MAX308CSE+ application, or MAX308CSE+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤7Ω), NO-off leakage <5nA at +85°C, enable switching times <250ns, TTL/CMOS logic compatibility, and plug-in upgrade path for DG408/DG508A.
Technical Context
The MAX308CSE+ implements a monolithic CMOS switch architecture with silicon-gate process optimization for low charge injection and high ESD tolerance (>2000V). Its decode logic accepts three address bits (A0–A2) and an active-high enable (EN) to select one of eight bidirectional analog channels (NO1–NO8) to the common terminal (COM).
It features matched on-resistance across all channels, flat RON over the full ±10V analog range, and low off-capacitance (CNO(OFF) = 3pF, CCOM(OFF) = 26pF), enabling high off-isolation (−75dB) and low crosstalk (−92dB) in precision signal routing applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | On-resistance 100Ω (typ), charge injection 25pC, operates up to +20V single supply only | Lacks dual-supply support and guaranteed flat RON; higher charge injection increases S/H error | Choose ADG408BRZ only if supply is limited to +20V and charge injection sensitivity is low |
| TMUX1308PWR | On-resistance 120Ω (max), rail-to-rail but rated for 5.5V max supply; no specified leakage at +85°C | Not suitable for ±10V or high-temp industrial use; lacks ESD rating >2kV | Select TMUX1308PWR only for low-voltage, commercial-temperature embedded systems with tight cost constraints |
Compared with ADG408BRZ and TMUX1308PWR, the MAX308CSE+ uniquely delivers guaranteed <5Ω on-resistance matching, <10pC charge injection, and full ±20V dual-supply operation - making it the only option qualified for precision, high-voltage, high-temperature multiplexing where channel consistency and signal integrity are critical.

FAQ
What is the maximum analog signal voltage range supported by the MAX308CSE+?
The MAX308CSE+ supports a ±10V analog signal range when operated with ±15V dual supplies. With single-supply operation (e.g., +12V), the usable analog range is 0V to +12V. The device maintains rail-to-rail signal handling, meaning the full supply voltage span is available for analog signals without clipping or distortion - a key requirement for interfacing with industrial sensors and DACs. This specification is confirmed in the Absolute Maximum Ratings and Typical Operating Characteristics sections of the official MAX308/MAX309 datasheet.
Is the MAX308CSE+ pin-compatible with the DG408 analog multiplexer?
Yes, the MAX308CSE+ is a plug-in upgrade for the industry-standard DG408. It uses identical pinout, logic interface (TTL/CMOS compatible), and functional behavior - including the same A0–A2 address decoding and EN enable control. No PCB layout or firmware modifications are required. This compatibility is explicitly stated in the General Description and Features sections of the MAX308/MAX309 datasheet, and verified through pin configuration diagrams and truth tables.
What is the on-resistance matching specification for the MAX308CSE+, and why does it matter?
The MAX308CSE+ guarantees on-resistance matching of <5Ω between any two channels. This means the difference between the highest and lowest RON values across all eight channels remains under 5Ω across temperature and signal voltage. This tight matching is essential in applications like multichannel data acquisition or programmable gain amplifiers, where mismatched channel resistance would introduce gain errors or differential nonlinearity. The value is tested and guaranteed per the Electrical Characteristics table (parameter ∆RON) in the MAX308/MAX309 datasheet.
Does the MAX308CSE+ support both single-supply and dual-supply operation?
Yes, the MAX308CSE+ supports both configurations: single supply from +5V to +30V (with V− tied to GND), and dual supply from ±5V to ±20V. This flexibility allows integration into battery-powered portable instruments (+5V to +12V), industrial PLCs (±15V), and military systems (±20V). The supply range and operational conditions are fully characterized in the Electrical Characteristics tables for both modes, and the device retains TTL/CMOS logic compatibility and low leakage performance across all supported supply combinations.
What is the charge injection specification for the MAX308CSE+, and how does it affect circuit performance?
The MAX308CSE+ guarantees charge injection of <10pC, measured at VCOM = ±10V with ±15V supplies. This low value minimizes voltage glitches on high-impedance nodes - especially critical in sample-and-hold circuits, integrators, or precision ADC front-ends. Excessive charge injection causes settling errors and increased acquisition time. The <10pC spec is validated in the Electrical Characteristics table (Q parameter) and confirmed via Typical Operating Characteristics curve TOC-07, ensuring predictable performance in time-sensitive analog signal paths.
