Analog Devices Inc./Maxim Integrated MAX313EUE+

Overview

MAX313EUE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch designed for precision signal routing in bipolar and single-supply systems. It delivers 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail analog signal handling from ±4.5V to ±20V or +4.5V to +30V. It is used in audio signal routing, test equipment, and data acquisition where low distortion and tight channel matching are critical.

For engineers reviewing the MAX313EUE+ datasheet, MAX313EUE+ pinout, MAX313EUE+ application, or MAX313EUE+ equivalent, key selection criteria include guaranteed R_ON flatness (≤2Ω), off-leakage <2.5nA at +85°C, crosstalk >96dB at 20kHz, ESD tolerance >2000V per Method 3015.7, and TSSOP-16 package compatibility with space-constrained industrial and avionics layouts.

Technical Context

The MAX313EUE+ implements a fully complementary CMOS SPST switch architecture with independent logic-level control inputs (IN1–IN4) referenced to VL, enabling interface with 3V/5V digital controllers. Its internal charge-pump-free design ensures stable R_ON across ±10V analog signal ranges and supports break-before-make timing only in the MAX314 variant-not applicable here.

All four switches operate bidirectionally with matched conduction characteristics, and the device maintains rail-to-rail signal integrity without requiring external level-shifting circuitry. The 16-pin TSSOP package integrates dedicated V+, V−, GND, and VL pins to isolate logic and analog supply domains, minimizing coupling-induced noise in mixed-signal environments.

FAQ

What is the maximum analog signal voltage range supported by the MAX313EUE+?

The MAX313EUE+ supports an analog signal range of ±10V when operated from dual supplies (±4.5V to ±20V), and 0V to V+ when operated from a single supply (+4.5V to +30V). This rail-to-rail capability allows the MAX313EUE+ to pass full-scale signals without clipping, making it suitable for both bipolar sensor interfaces and unipolar industrial control applications.

Does the MAX313EUE+ require external blocking diodes for overvoltage protection?

No, the MAX313EUE+ does not require external blocking diodes for standard overvoltage conditions within its Absolute Maximum Ratings (e.g., V+ to V− ≤ +44V). Internal protection diodes clamp signals exceeding V+ or V−, but forward current must be limited to 30mA. External diodes are only recommended if input signals may exceed these limits - a design choice confirmed in Figure 1 of the MAX313EUE+ datasheet.

How does the MAX313EUE+ differ from the MAX312EUE+ and MAX314EUE+ in functionality?

The MAX313EUE+ is a quad normally open (NO) switch, whereas the MAX312EUE+ is quad normally closed (NC) and the MAX314EUE+ combines two NO and two NC switches. All three share identical electrical specs (R_ON, leakage, timing), but their truth tables and default states differ - meaning MAX313EUE+ opens all paths at power-up unless actively enabled, which is critical for fail-safe signal isolation in safety-critical systems.

Can the MAX313EUE+ operate with VL tied to V+?

Yes, the MAX313EUE+ supports VL tied directly to V+, enabling single-supply operation with TTL/CMOS logic compatibility. When VL = V+, the input high threshold becomes ~2.4V (relative to GND), satisfying standard 5V logic levels. This configuration simplifies power sequencing and eliminates the need for a separate logic supply - a verified operating mode documented in the MAX313EUE+ Electrical Characteristics table under "Logic Supply Current" conditions.

What is the thermal resistance (θ_JA) of the MAX313EUE+ in its TSSOP-16 package?

According to the MAX313EUE+ datasheet's Absolute Maximum Ratings table, the thermal resistance θ_JA for the TSSOP-16 package is 149°C/W. This value assumes standard JEDEC JESD51-7 PCB mounting conditions (two-layer board, 1in² copper pad). For high-power-density layouts, designers should verify junction temperature using actual power dissipation (I²R_ON + quiescent supply current) and ambient conditions to ensure operation remains within the -40°C to +85°C specified range.
