Analog Devices Inc./Maxim Integrated MAX313CUE+T

Overview

MAX313CUE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch optimized 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 MAX313CUE+T datasheet, MAX313CUE+T pinout, MAX313CUE+T application, or MAX313CUE+T equivalent, key selection criteria include guaranteed R_ON flatness (≤2Ω), off-leakage ≤2.5nA at +85°C, ESD tolerance >2000V per Method 3015.7, crosstalk >96dB at 20kHz, and TSSOP-16 package compatibility with space-constrained PCB layouts.

Technical Context

The MAX313CUE+T implements four independent SPST NO switches using CMOS process technology with integrated charge-pump logic-level translation, enabling operation with logic supply (VL) as low as 2.4V while supporting analog rails up to ±20V. Its architecture ensures symmetrical conduction-identical R_ON in both directions-and guarantees monotonic R_ON variation across the full analog signal range (±10V).

It features break-before-make timing only in the MAX314 variant; the MAX313CUE+T has no internal interlock-each switch operates independently with 425ns max turn-on time (single supply, V+ = 12V) and 225ns max turn-off time. Input logic thresholds are TTL-compatible (V_INH = 2.4V, V_INL = 0.8V), and all channels share a common VL and GND reference.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal voltage range supported by the MAX313CUE+T?

The MAX313CUE+T supports an analog signal range of ±10V when operated from dual supplies (±4.5V to ±20V), or 0V to V+ when used with a single supply (+4.5V to +30V). This rail-to-rail capability ensures full-swing signal integrity without clipping, making it ideal for interfacing with ±15V op-amps or 24V industrial sensors. The device's internal structure clamps signals beyond V+ or V− via diodes, but sustained overvoltage requires external protection.

Does the MAX313CUE+T require a negative supply to operate?

No-the MAX313CUE+T operates fully with a single positive supply (V+ = +4.5V to +30V) and GND. In this configuration, V− is tied to GND, and analog signals swing from 0V to V+. Dual-supply operation (±4.5V to ±20V) is optional and enables bipolar signal handling-for example, ±10V audio or sensor outputs-but is not mandatory. The VL pin remains functional in either mode to accommodate logic-level translation.

Can the MAX313CUE+T be used in audio applications without audible distortion?

Yes-the MAX313CUE+T is explicitly characterized for low-distortion audio use. With 6.5Ω typical R_ON, ≤2Ω R_ON flatness over ±10V, and <−100dB THD at 1kHz (per typical curves), it maintains signal fidelity in line-level routing. Its >96dB crosstalk at 20kHz prevents channel bleed, and ±30pC charge injection avoids pop/click artifacts in switched gain stages-key advantages over generic analog switches in professional audio gear.

What is the purpose of the VL pin on the MAX313CUE+T?

The VL pin on the MAX313CUE+T sets the logic threshold reference for the IN1–IN4 control inputs. It accepts 2.4V to V+, enabling direct interfacing with 3.3V or 5V microcontrollers-even when V+ is +24V or ±15V. This eliminates level-shifters in mixed-voltage systems. When VL is tied to V+, the inputs become compatible with the same supply; when tied to 3.3V, they accept 3.3V logic while switching ±15V analog signals-making MAX313CUE+T uniquely flexible for modern embedded designs.

Is the MAX313CUE+T pin-compatible with the DG412 analog switch?

Yes-the MAX313CUE+T is explicitly designed as a pin-compatible, performance-enhanced replacement for the DG412. Both use identical TSSOP-16 pinouts, NO-switch topology, and TTL-compatible logic inputs. However, MAX313CUE+T improves on R_ON (6.5Ω vs. 10Ω typical), adds VL for level-shifting, guarantees R_ON matching (≤1.5Ω), and offers superior crosstalk (>96dB vs. ~80dB). No PCB changes are needed for drop-in replacement in existing DG412 layouts.
