Analog Devices Inc./Maxim Integrated MAX313EUE+T

Overview

MAX313EUE+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 signal handling across ±4.5V to ±20V dual supplies or +4.5V to +30V single supply - enabling low-distortion audio routing and high-fidelity data acquisition.

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

Technical Context

The MAX313EUE+T implements a fully complementary CMOS SPST switch architecture with independent logic-level control inputs (IN1–IN4) and dedicated VL pin for TTL/CMOS-compatible logic threshold setting. Its channel structure isolates COM–NO paths without internal NC connections, ensuring true NO behavior across full analog signal range (±10V with dual supplies, 0V to V+ with single supply).

Dynamic performance is defined by 65ns typical turn-on time (t_ON) and 235ns typical turn-off time (t_OFF) at V_COM = ±10V, with charge injection limited to ±30pC - critical for sample-and-hold accuracy. Off-isolation exceeds 65dB at 1MHz, and crosstalk remains >96dB at 20kHz between any two switches.

Key Specifications

Pinout & Package

MAX313EUE+T is housed in a 16-pin TSSOP package (4.4mm width, 0.65mm pitch) with exposed pad for thermal enhancement. Pin numbering follows standard JEDEC TSSOP layout (pin 1 top-left, counterclockwise).

FAQ

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

The MAX313EUE+T supports analog signals from V− to V+ - up to ±10V with dual supplies (±4.5V to ±20V) or 0V to V+ (up to +30V) with single supply. This rail-to-rail capability ensures full dynamic range utilization without clipping in precision signal chains, and is explicitly verified in the Electrical Characteristics tables for both dual- and single-supply configurations.

Does the MAX313EUE+T require external pull-up or pull-down resistors on its logic inputs?

No, the MAX313EUE+T logic inputs (IN1–IN4) are TTL/CMOS-compatible and do not require external biasing. With VL tied to +5V or V+, the device accepts 0.8V (max) logic-low and 2.4V (min) logic-high thresholds - meeting standard 5V logic levels without additional components, as confirmed in the Electrical Characteristics table under "Input Current with Input Voltage High/Low".

How does the MAX313EUE+T achieve low THD in audio applications?

The MAX313EUE+T achieves low total harmonic distortion (THD) via 6.5Ω typical on-resistance with only 2Ω max flatness over signal range - minimizing nonlinear voltage-dependent resistance effects. Its symmetric CMOS structure and low charge injection (±30pC) prevent waveform distortion, as validated in Figure 9 ("THD vs. Frequency") of the datasheet using 5V_RMS signals into 600Ω loads.

Can the MAX313EUE+T be used in single-supply +5V systems?

Yes, the MAX313EUE+T operates from +4.5V to +30V single supply. At +5V, it maintains functional R_ON (≤12.5Ω typ) and leakage specs, though R_ON increases slightly versus higher voltages. The datasheet confirms this in the "Single Supply" Electrical Characteristics table (V+ = 5V row), and Figure 3 shows valid operation down to V+ = 2.7V.

What is the thermal performance of the MAX313EUE+T in TSSOP-16 package?

The MAX313EUE+T in TSSOP-16 has a thermal derating factor of 6.7mW/°C above +70°C, with 457mW maximum continuous power dissipation at TA = +70°C. Its exposed pad (visible in package drawings) enables enhanced heat transfer when soldered to a thermal plane - critical for sustained operation in compact test equipment enclosures where ambient temperatures exceed 70°C.
