Analog Devices Inc./Maxim Integrated MAX339ESE+

Overview

The MAX339ESE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer designed to route one of four bidirectional analog inputs per section (NO1A–NO4A and NO1B–NO4B) to respective common outputs (COMA, COMB) using 2-bit binary address control (A0, A1). It features ≤400Ω on-resistance, <20pA NO-off leakage at +25°C, 1.5pC typical charge injection, and operates from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply. It serves in precision data-acquisition systems requiring low signal distortion and rail-to-rail analog handling.

For engineers reviewing the MAX339ESE+ datasheet, MAX339ESE+ pinout, MAX339ESE+ application, or MAX339ESE+ equivalent, key selection criteria include guaranteed low off-leakage (<20pA), low charge injection (1.5pC typ), TTL/CMOS-compatible enable and address inputs, dual- or single-supply flexibility, and compatibility with DG509A replacement requirements in military and test equipment designs.

Technical Context

The MAX339ESE+ implements fully bidirectional CMOS switch architecture with independent decode logic for each 4-channel section, supporting simultaneous or separate channel selection via shared A0/A1 and dedicated EN. Its silicon-gate 44V process enables rail-to-rail analog signal handling (±15V dual, 0–12V single) while maintaining sub-500ns transition time and break-before-make switching.

All digital inputs (EN, A0, A1) are TTL/CMOS-compatible across full temperature range and supply voltages (±4.5V to ±18V), with input leakage <±1.0µA. ESD protection exceeds 2000V per Method 3015.7, and on-resistance matching between channels is ≤10Ω at +25°C - critical for multi-channel gain/offset calibration in instrumentation.

FAQ

What supply configurations does the MAX339ESE+ support?

The MAX339ESE+ operates from dual supplies of ±4.5V to ±20V or a single supply of +4.5V to +30V. When using single supply, V− must be connected to GND. Unbalanced supplies (e.g., +24V/−5V) are also supported, provided the total voltage difference does not exceed 44V. The MAX339ESE+ maintains full functionality and specified leakage/performance across all supported configurations.

Is the MAX339ESE+ pin-compatible with the DG509A?

Yes, the MAX339ESE+ is a pin-compatible upgrade for the DG509A in 16-pin narrow SOIC (S16+1) packaging. All pin functions - including A0, A1, EN, COMA, COMB, NO1A–NO4A, NO1B–NO4B, V+, V−, and GND - match identically. No PCB layout changes are needed when replacing DG509A with MAX339ESE+, though improved ESD rating (>2000V) and lower leakage provide immediate system-level benefits.

What is the maximum allowable analog signal voltage range for the MAX339ESE+?

The MAX339ESE+ supports analog signals from V− to V+ - i.e., rail-to-rail operation. With ±15V dual supplies, the full range is −15V to +15V. With +12V/0V single supply, it is 0V to +12V. Absolute maximum ratings limit VNO and VCOM to (V− − 2V) to (V+ + 2V), but normal operation must stay within the supply rails to avoid clamping diode conduction. The MAX339ESE+ guarantees performance across this full range.

How does charge injection affect system accuracy in sample-and-hold circuits using the MAX339ESE+?

With 1.5pC typical charge injection, the MAX339ESE+ induces a voltage step ΔV = Q/CL on the hold capacitor. For a 100pF capacitor, this yields a 15mV glitch - manageable with proper capacitor sizing and settling time allowance. In high-resolution systems, using CL ≥ 1nF reduces ΔV to ≤1.5mV. The MAX339ESE+'s guaranteed low charge injection directly enables 16-bit+ sample-and-hold accuracy without additional correction circuitry.

Does the MAX339ESE+ require external decoupling capacitors?

Yes, the MAX339ESE+ requires local ceramic decoupling: at least one 0.1µF capacitor between V+ and GND, and another between V− and GND, placed within 5mm of the respective pins. Additional bulk capacitance (e.g., 4.7µF tantalum) is recommended for systems with dynamic load currents. These capacitors suppress supply noise coupling into analog paths and ensure stable switching behavior - especially critical for maintaining <20pA leakage and <500ns transition time in the MAX339ESE+.
