Product details
Overview
MAX398ESE from Maxim Integrated is an 8-channel precision CMOS analog multiplexer with low on-resistance (<100Ω), matched within 6Ω between channels, flat on-resistance (≤11Ω over signal range), and guaranteed charge injection <5pC. It operates from +3V to +15V single supply or ±3V to ±8V dual supplies and is rated for -40°C to +85°C industrial temperature range. It serves as a high-accuracy signal routing switch in data-acquisition and test equipment.
For engineers reviewing the MAX398ESE datasheet, MAX398ESE pinout, MAX398ESE application, or MAX398ESE equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options - all grounded in Maxim's official documentation and electrical characterization data.
Technical Context
The MAX398ESE implements a monolithic CMOS analog switch architecture with silicon-gate process optimization for low leakage and rail-to-rail signal handling. Its decoder logic accepts three address inputs (A0–A2) and an active-high enable (EN) to select one of eight bidirectional analog channels (NO1–NO8) to connect to the common port (COM).
It guarantees electrostatic discharge protection >2000V and maintains sub-250ns transition time across its full operating voltage and temperature range. The device supports break-before-make switching (tOPEN ≤ 40ns typical) and exhibits <2.5nA COM off-leakage at +85°C under dual-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 8-channel single-ended analog multiplexer with one common (COM) terminal |
| On-Resistance (RON) | <100Ω max at +25°C (V+ = +5V, V− = −5V); enables minimal signal attenuation in precision measurement paths |
| RON Matching | <6Ω max difference between any two channels; critical for gain/offset matching in multi-channel instrumentation |
| Charge Injection | <5pC max; limits voltage glitch on sampled-hold capacitors, preserving ADC accuracy |
| Off-Leakage (COM) | <2.5nA at +85°C (dual supply); ensures stable DC bias integrity in high-impedance sensor interfaces |
| Supply Range | +3V to +15V single supply or ±3V to ±8V dual supply; supports battery-powered and industrial rail-flexible designs |
| Logic Compatibility | TTL/CMOS-input compatible (VIL ≤ 0.8V, VIH ≥ 2.4V); interoperable with standard microcontrollers and FPGAs |
Pinout & Package
The MAX398ESE is housed in a 16-pin narrow SOIC (SOIC-N) package (package code S16-1), with gull-wing leads, 0.150" body width, and exposed pad not present (QFN variant has EP; SOIC-N does not). Pin 1 is A0 (LSB address), pin 8 is COM, pin 16 is V+, and pin 14 is GND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | A0, A1, A2 | Binary address inputs selecting channel NO1–NO8; decoded internally with no external logic required |
| 4–7, 9–12 | NO1–NO4, NO5–NO8 | Bidirectional analog input terminals; each connects to COM when selected; 0.1pF crosstalk isolation minimizes inter-channel coupling |
| 8 | COM | Common analog I/O node; handles rail-to-rail signals up to V+ and down to V−; low capacitance (54pF typ) preserves bandwidth |
| 13 | V+ | Positive supply rail; must be powered before V− and logic inputs to prevent latch-up per sequencing guidelines |
| 14 | GND | Ground reference for logic and analog sections; shared return path requires careful PCB layout to avoid noise coupling |
| 15 | V− | Negative supply rail for dual-supply operation; tied to GND for single-supply mode (+3V to +15V) |
| 16 | EN | Active-high enable; disables all switches when low (high-impedance state); supports power-gating and system-level control |
Key Features
| Feature | Design Value |
|---|---|
| Precision RON flatness | ≤11Ω variation over full analog signal range (±4.5V), ensuring consistent gain across input amplitude |
| Guaranteed ESD robustness | >2000V HBM - eliminates need for external protection diodes in most industrial environments |
| Low power consumption | <300µW typical at +25°C - enables integration into always-on, low-quiescent systems |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±5V sensor front-ends and audio routing |
| Pin compatibility | Direct replacement for DG408, DG508A, and industry-standard 8-channel mux footprints - reduces redesign effort |

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, ±5V max supply, RON = 100Ω typ, charge injection = 25pC - higher than MAX398ESE's <5pC | Less suitable for precision sample-and-hold; better for general-purpose switching where speed > accuracy | Select ADG408BRZ only if lower cost outweighs need for sub-5pC charge injection and tighter RON matching. |
| TMUX6208RTER | 8-channel, 12V max supply, RON = 4.5Ω typ, but specified only for +2.7V to +12V single supply - no bipolar support | Not viable for ±5V sensor interfaces; requires level-shifting for TTL/CMOS logic interfacing | Choose TMUX6208RTER only for low-RON single-supply systems where bipolar operation and ultra-low charge injection are unnecessary. |
Compared with ADG408BRZ and TMUX6208RTER, the MAX398ESE uniquely combines bipolar supply flexibility, guaranteed <5pC charge injection, and <6Ω RON matching - making it the preferred choice for high-fidelity, temperature-stable, multi-rail analog signal routing.

FAQ
What is the maximum analog signal range supported by the MAX398ESE?
The MAX398ESE supports rail-to-rail analog signals from V− to V+ across its full supply range. With ±5V dual supplies, the signal range is ±4.5V; with +5V single supply, it is 0V to +4.5V. This range is guaranteed by design and verified in the datasheet's Electrical Characteristics tables for both dual- and single-supply configurations. The MAX398ESE maintains low on-resistance flatness (≤11Ω) across this entire range, ensuring consistent performance regardless of input voltage level.
Does the MAX398ESE require external protection diodes for overvoltage conditions?
No, the MAX398ESE does not require external protection diodes under normal operating conditions. Its internal protection diodes clamp signals to safe levels, and it is rated for ESD >2000V HBM. However, if absolute maximum ratings risk being exceeded (e.g., V+ transient >+17V), external series diodes may be added - though this reduces analog signal range by one diode drop and is not recommended for single-supply operation. The MAX398ESE's robust internal structure eliminates the need for such components in compliant designs.
Is the MAX398ESE pin-compatible with the DG408 multiplexer?
Yes, the MAX398ESE is explicitly pin-compatible with the DG408, DG409, DG508A, and DG509A, as confirmed in the "Features" section and "Pin Configurations" diagram of the official datasheet. All address, enable, supply, ground, and channel pin assignments match exactly in the 16-pin narrow SOIC package. This allows direct substitution without PCB layout changes, provided supply and signal voltage ranges align with the MAX398ESE's specifications.
What is the guaranteed on-resistance matching specification for the MAX398ESE?
The MAX398ESE guarantees on-resistance matching of less than 6Ω between any two channels (ΔRON = RON(MAX) − RON(MIN)). This specification is tested and guaranteed over the full industrial temperature range (−40°C to +85°C) and applies to all eight channels. It is critical for applications requiring matched gain or offset across multiple signal paths, such as multi-channel data acquisition and precision instrumentation where channel-to-channel consistency directly impacts measurement accuracy.
Can the MAX398ESE operate from a +3V single supply?
Yes, the MAX398ESE is fully specified for +3V single-supply operation. At V+ = +3V and V− = 0V, it delivers RON ≤ 425Ω (typical), transition time ≤ 575ns, and charge injection ≤ 5pC - all guaranteed per the "Electrical Characteristics-Single +3V" table. Its TTL/CMOS-compatible inputs function correctly with 0.8V/2.4V thresholds, and the device maintains rail-to-rail signal handling from 0V to nearly V+. This makes the MAX398ESE suitable for ultra-low-voltage portable and energy-constrained systems.
