Analog Devices Inc./Maxim Integrated DG506AEWI

Overview

DG506AEWI from Maxim Integrated is a monolithic CMOS 16-channel analog multiplexer (1-of-16) in a 28-pin wide SOIC package, operating from ±4.5V to ±18V supplies with 270Ω typical on-resistance, 0.6μs switching time, and break-before-make switching. It serves as a precision signal routing device in data acquisition systems requiring low leakage (±1nA off-leakage), symmetrical bidirectional operation, and TTL/CMOS-compatible logic inputs.

For engineers reviewing the DG506AEWI datasheet, DG506AEWI pinout, DG506AEWI application, or DG506AEWI equivalent, this page delivers verified electrical parameters, validated pin functions, real-world use cases in control and logging systems, and two confirmed drop-in alternatives for supply continuity and design flexibility.

Technical Context

The DG506AEWI implements a single-pole, 16-throw analog switch architecture with address-decoded channel selection via A0–A3 and EN control. Its CMOS construction ensures latch-up immunity even with input signals present during power-down, and its symmetrical analog path supports bidirectional signal flow without polarity constraints.

Break-before-make timing (0.2μs) prevents momentary shorting between channels during switching, while the enable-controlled architecture allows full system-level power gating. All digital inputs meet TTL and CMOS voltage thresholds, enabling direct interfacing with microcontrollers and FPGAs without level-shifting.

FAQ

What is the maximum analog signal voltage range supported by the DG506AEWI?

The DG506AEWI supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow V+ up to +44V and V− down to −44V, but the usable linear analog range remains bounded by the supply rails - i.e., signals must stay between V− and V+. This makes DG506AEWI suitable for industrial ±10V and ±15V systems without external clamping.

Does the DG506AEWI require external pull-up or pull-down resistors on its address lines?

No, the DG506AEWI does not require external pull-up or pull-down resistors on A0–A3 or EN. Its address and enable inputs are TTL/CMOS compatible with defined thresholds (VAL ≤ 0.8V for logic low, VAH ≥ 2.4V for logic high) and exhibit low input current (±0.002µA typical). Microcontroller GPIOs or FPGA outputs can drive these pins directly without additional biasing components.

Can the DG506AEWI operate with asymmetric supplies, such as +12V and −5V?

Yes, the DG506AEWI supports asymmetric dual supplies - for example, +12V and −5V - as long as both V+ and V− remain within their absolute maximum ratings (V+ ≤ +44V, V− ≥ −44V) and the total supply span meets minimum requirements. However, the usable analog signal range becomes limited to the narrower of the two supply magnitudes (e.g., −5V to +12V), and performance parameters like R_DS(ON) may vary slightly versus symmetric conditions.

Is the DG506AEWI pin-compatible with the DG506ACWI or DG506AMWI variants?

Yes, the DG506AEWI is fully pin-compatible with DG506ACWI and DG506AMWI - all use the same 28-pin wide SOIC (W28-5) package and identical pinout. The key differences lie in temperature grade (DG506AEWI: 0°C to +70°C; DG506AMWI: −55°C to +125°C) and internal process screening, not physical layout or electrical interface.

What is the purpose of the break-before-make feature in the DG506AEWI, and how is it implemented?

The break-before-make feature in the DG506AEWI ensures that one channel is fully disconnected before the next is connected, preventing momentary shorts between analog sources. It is implemented via internal timing control with a guaranteed 0.2μs open interval during address transitions. This eliminates signal glitches and cross-talk in critical applications like aircraft HUDs and automated test systems where channel integrity is non-negotiable.
