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, featuring break-before-make switching, <1nA off-leakage at ±10V, and 270Ω typical on-resistance at ±15V - used for precision signal routing in data acquisition systems.

For engineers reviewing the DG506AEWI+ datasheet, DG506AEWI+ pinout, DG506AEWI+ application, or DG506AEWI+ equivalent, this page delivers verified electrical parameters, validated pin functions, confirmed drop-in alternatives, and real-world use context for analog channel selection in industrial and aerospace instrumentation.

Technical Context

The DG506AEWI+ implements a fully bidirectional, symmetrical analog switch matrix controlled by four TTL/CMOS-compatible address inputs (A0–A3) and an active-high enable (EN), supporting ±15V analog signal range with no latch-up under power-off input conditions. Its break-before-make architecture prevents momentary shorting between channels during switching transitions.

It uses monolithic low-power CMOS construction with internal protection diodes clamping signals exceeding V+ or V−, and guarantees functional operation across 0°C to +70°C ambient temperature with guaranteed R_DS(ON) matching ≤6% between channels and off-isolation of 68dB at 500kHz.

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 functional analog swing is limited to the supply rails. This makes DG506AEWI+ suitable for industrial sensor interfaces and legacy ±15V instrumentation systems without external level shifting.

Does the DG506AEWI+ require external pull-up resistors on its address or enable pins?

No, the DG506AEWI+ does not require external pull-up resistors. Its address inputs (A0–A3) and enable (EN) pin are TTL- and CMOS-compatible with guaranteed logic thresholds (VAL ≤ 0.8V for low, VAH ≥ 2.4V for high) and input currents below ±0.002μA at 25°C - allowing direct connection to microcontroller GPIOs or FPGA outputs without additional components.

Is the DG506AEWI+ pin-compatible with the original Siliconix DG506A?

Yes, the DG506AEWI+ is pin-compatible with the original Siliconix DG506A, as confirmed by Maxim's datasheet stating "drop-in replacements for Siliconix's DG506A and DG507A." Both share identical 28-pin wide SOIC pinout, supply connections, address mapping, and functional behavior - enabling direct substitution without PCB modification.

What is the typical on-resistance matching between channels of the DG506AEWI+?

The DG506AEWI+ guarantees ≤6% variation in drain-to-source on-resistance (R_DS(ON)) between any two channels, calculated as (R_DS(ON)MAX − R_DS(ON)MIN) / R_DS(ON)AVE. At ±15V supplies and 25°C, typical R_DS(ON) is 270Ω, meaning channel-to-channel mismatch stays within ±8Ω - critical for gain-matched multi-channel instrumentation.

Can the DG506AEWI+ operate from a single +12V supply?

No, the DG506AEWI+ requires dual supplies (V+ and V−) to support its ±15V analog signal range and internal CMOS switch architecture. It cannot operate from a single +12V rail. For single-supply applications, consider alternatives like the MAX306 or ADG506A, which are specified for +15V-only or +12V operation with reduced analog range.
