Analog Devices Inc./Maxim Integrated DG411CEE

Overview

DG411CEE from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, rail-to-rail analog signal handling (±15V), and TTL/CMOS logic compatibility - enabling reliable use in sample-and-hold circuits and audio signal routing.

For engineers reviewing the DG411CEE datasheet, DG411CEE pinout, DG411CEE application, or DG411CEE equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω), low channel-to-channel R_DS(ON) mismatch (3Ω max), ESD tolerance (2000V min), and operation across ±4.5V to ±20V or +10V to +30V supplies.

Technical Context

The DG411CEE implements four independent NC SPST switches fabricated using a 44V silicon-gate process, supporting bidirectional conduction with matched on-resistance across all channels. Its architecture guarantees low charge injection (10pC max) and flat on-resistance over the full analog signal range (±15V), critical for minimizing distortion in precision sampling paths.

It operates from dual supplies (±4.5V to ±20V) or single supply (+10V to +30V), with VL referenced to +5V for TTL compatibility. Switching times are tightly specified: t_ON ≤ 150ns and t_OFF ≤ 100ns under standard load conditions (RL = 300Ω, CL = 35pF).

Key Specifications

Pinout & Package

DG411CEE is supplied in a 16-pin TSSOP package (package code U16-2), with exposed pad connected to V+ per manufacturer recommendation. Pin numbering follows standard JEDEC TSSOP layout.

FAQ

What is the logic polarity of DG411CEE?

The DG411CEE is a normally closed (NC) analog switch: each channel conducts when its corresponding INx pin is logic low (≤0.8V), and opens when INx is logic high (≥2.4V). This active-low behavior is fixed by internal design and cannot be inverted. DG411CEE requires VL = +5V for TTL compatibility, or VL tied to V+ for CMOS-level inputs.

Does DG411CEE support single-supply operation?

Yes, DG411CEE supports single-supply operation from +10V to +30V. In this mode, connect V− to GND, set VL = +5V, and ensure analog signals remain within 0V to V+ (rail-to-rail). On-resistance increases slightly versus bipolar operation, and switching speed degrades - e.g., t_ON rises to 250ns typical at +12V supply per datasheet Section 4.

What is the maximum analog signal range for DG411CEE?

The maximum analog signal range for DG411CEE is from V− to V+, supporting ±15V (i.e., −15V to +15V) with ±15V supplies, or 0V to +12V with +12V single supply. Signals exceeding V+ or V− are clamped by internal diodes; forward current must be limited to 30mA continuous or 100mA pulsed to avoid damage per Absolute Maximum Ratings.

Is DG411CEE pin-compatible with older DG411 variants?

Yes, DG411CEE is pin-compatible with industry-standard DG411 devices in the same 16-pin TSSOP package (U16-2), including DG411CUE and DG411EUE. The pinout, footprint, and logic interface are identical; improvements (e.g., lower leakage, tighter R_DS(ON) match) require no PCB changes and provide immediate performance uplift in existing designs.

How does DG411CEE handle electrostatic discharge?

DG411CEE is rated for ≥2000V human-body-model (HBM) ESD per Method 3015.7, verified during production test. This rating applies to all pins, including analog I/O (S/D) and digital inputs (INx). No external protection is required for standard handling, though board-level TVS diodes are recommended in high-risk environments such as automated test handlers or field-replaceable modules.
