Analog Devices Inc./Maxim Integrated DG506ACWI+T

Overview

DG506ACWI+T 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 dual supplies, with 270Ω typical on-resistance, <1µs switching time, and break-before-make architecture - used for precision signal routing in data acquisition systems.

For engineers reviewing the DG506ACWI+T datasheet, DG506ACWI+T pinout, DG506ACWI+T application, or DG506ACWI+T equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases, and confirmed drop-in alternatives - all grounded in Maxim's official DG506A/DG507A datasheet Rev 4 (6/12).

Technical Context

The DG506ACWI+T implements a single-pole, 16-throw (SP16T) analog switch matrix controlled by four TTL/CMOS-compatible address inputs (A0–A3) and an active-high enable (EN). It uses symmetrical bidirectional CMOS transmission gates with latch-up-proof construction.

Its break-before-make timing ensures no transient shorting between channels during address transitions, and its ±15V analog signal range supports rail-to-rail operation across the full supply span - critical for industrial sensor interfacing and high-fidelity test equipment.

FAQ

What is the maximum analog signal voltage range supported by the DG506ACWI+T?

The DG506ACWI+T supports an analog signal range of ±15V when operated from ±15V supplies - meaning signals from -15V to +15V can pass through any selected channel without clipping or distortion. This range scales linearly with supply voltage; for example, at ±12V supplies, the usable analog range is ±12V. The device's absolute maximum ratings allow V+ up to +44V and V− down to -44V, but functional analog swing remains bounded by the supply rails.

Does the DG506ACWI+T require external pull-up or pull-down resistors on its address or enable pins?

No, the DG506ACWI+T does not require external pull-up or pull-down resistors on A0–A3 or EN pins because its digital inputs are TTL- and CMOS-compatible with guaranteed thresholds (VAL ≤ 0.8V for logic low, VAH ≥ 2.4V for logic high) and low input current (±0.002µA typical). However, in noisy industrial environments or when driven by high-impedance sources, a 10kΩ pull-down on EN is recommended to ensure default-off behavior during power-up.

Can the DG506ACWI+T be used with single-supply operation?

No - the DG506ACWI+T is designed exclusively for dual-supply operation (±V). Its internal CMOS switch structure requires symmetrical positive and negative rails to bias the transmission gates correctly. Attempting single-supply use (e.g., V+ = +15V, V− = GND) violates the absolute maximum rating for GND (25V) and causes undefined switching behavior, increased leakage, and potential latch-up. For single-supply applications, consider Maxim's MAX4617 or ADG1414 families instead.

What is the thermal performance difference between the DG506ACWI+T and the DG506ADJ package?

The DG506ACWI+T in 28-pin wide SOIC has a thermal resistance θ_JA of 125°C/W and a continuous power dissipation limit of 1000mW at +70°C (derated 12.5mW/°C above), while the DG506ADJ in 28-pin plastic DIP has θ_JA ≈ 135°C/W and 1143mW limit (derated 14.3mW/°C). In practice, the SOIC package runs cooler under identical load due to better copper pad heat spreading - critical for sustained operation in enclosed industrial enclosures.

Is the DG506ACWI+T pin-compatible with the original Intersil IH6116?

Yes - the DG506ACWI+T is explicitly documented as a drop-in replacement for Intersil's IH6116, sharing identical pinout, electrical specifications, and functional behavior. Both devices use the same 28-pin wide SOIC footprint, match on all address, enable, supply, ground, and channel pin assignments, and meet or exceed IH6116's R_DS(ON), leakage, and switching time specs - enabling direct substitution without PCB or firmware changes.
