Analog Devices Inc./Maxim Integrated DG413EUE+T

Overview

DG413EUE+T from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in bipolar or single-supply systems. It delivers 45Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies-enabling use in battery-operated test equipment and military radio front-ends.

For engineers reviewing the DG413EUE+T datasheet, DG413EUE+T pinout, DG413EUE+T application, or DG413EUE+T equivalent, key selection criteria include guaranteed R_ON matching (≤3Ω), rail-to-rail analog signal handling (±15.5V), break-before-make timing (25ns), TTL/CMOS logic compatibility, and ESD tolerance (2000V per Method 3015.7).

Technical Context

The DG413EUE+T implements four independent CMOS transmission gates fabricated in a 44V silicon-gate process, supporting bidirectional signal flow with matched channel characteristics. Its logic interface accepts 0.8V/2.4V thresholds and operates with VL tied to 5V (TTL) or V+ (CMOS), while internal substrate connection to V+ enables robust operation across wide supply ranges.

Switching behavior is defined by discrete IN1–IN4 control inputs driving complementary gate structures per channel; NC channels (1 & 4) conduct when IN = 0V, NO channels (2 & 3) conduct when IN = 5V. Break-before-make timing ensures no overlap between adjacent channel conduction states, critical for avoiding signal shorting in multiplexed audio or guidance systems.

FAQ

What is the maximum analog signal voltage range supported by the DG413EUE+T?

The DG413EUE+T supports an analog signal range of ±15.5V when operated with ±16.5V supplies, and 0V to +12V with a +12V single supply. This rail-to-rail capability allows direct interfacing with standard op-amp outputs and sensor signals without level shifting. The DG413EUE+T maintains specified R_ON flatness (Δ4Ω) across this full range under bipolar conditions.

Does the DG413EUE+T require external pull-up resistors on its logic inputs?

No, the DG413EUE+T does not require external pull-ups. Its IN1–IN4 inputs are TTL/CMOS-compatible with guaranteed thresholds of 0.8V (V_IL) and 2.4V (V_IH) when VL = 5V. The DG413EUE+T draws less than 1µA input current across temperature, enabling direct connection to microcontroller GPIOs or FPGA outputs without additional biasing components.

How does the DG413EUE+T handle power supply sequencing during startup?

The DG413EUE+T recommends V+ be applied first, followed by VL, then V-, and finally logic inputs to prevent latch-up or excessive leakage. If strict sequencing isn't feasible, external diodes can be added to V+ and V− pins per Figure 1 in the datasheet-reducing analog range by 1V but preserving DG413EUE+T's low R_ON and leakage specs. This protection method is validated for DG413EUE+T in MIL-STD-883B environments.

Can the DG413EUE+T be used in a single-supply configuration with 3.3V logic control?

Yes-the DG413EUE+T supports 3.3V logic inputs when VL is tied to 3.3V, provided V+ ≥ 10V and V− = 0V. However, TTL compatibility (0.8V/2.4V thresholds) is only guaranteed at VL = 5V. At VL = 3.3V, the DG413EUE+T still functions but may exhibit marginal noise margin; for robust 3.3V systems, verify logic levels with actual board-level testing using the DG413EUE+T's measured I_INL/I_INH values.

What is the thermal performance of the DG413EUE+T in its TSSOP package?

The DG413EUE+T in 16-pin TSSOP has a thermal resistance θ_JA of 149°C/W (derating 6.7mW/°C above +70°C), resulting in a max power dissipation of 457mW at +70°C ambient. Under typical operation (35µW quiescent + <1mW dynamic), junction temperature rise is negligible. The DG413EUE+T's −40°C to +85°C rating ensures reliable function in uncontrolled industrial enclosures without forced airflow.
