Analog Devices Inc./Maxim Integrated DG506ADN+T

Overview

DG506ADN+T from Maxim Integrated is a monolithic CMOS 16-channel analog multiplexer (1-of-16) with break-before-make switching, ±4.5V to ±18V dual-supply operation, 270Ω typical on-resistance at ±15V, and TTL/CMOS-compatible logic inputs. It routes analog signals in precision data acquisition systems where channel isolation and rail-to-rail signal handling are critical.

For engineers reviewing the DG506ADN+T datasheet, DG506ADN+T pinout, DG506ADN+T application, or DG506ADN+T equivalent, this device supports high-accuracy signal routing in aerospace HUDs, industrial control systems, and portable instrumentation requiring latch-up immunity and low power consumption.

Technical Context

The DG506ADN+T implements a fully symmetrical, bidirectional analog switch matrix controlled by four address bits (A0–A3) and an active-high enable input (EN). Its CMOS architecture ensures matched on-resistance across all 16 channels and guarantees no latch-up when powered down with analog signals present.

It features break-before-make timing (0.2µs minimum open interval) to prevent signal shorting during channel transitions, and supports analog signal ranges from –15V to +15V with <±1nA off-leakage at 25°C. All digital inputs tolerate voltages up to V+ + 2V or –2V, enabling robust interfacing with mixed-voltage systems.

FAQ

What is the maximum analog signal voltage range supported by DG506ADN+T?

DG506ADN+T supports an analog signal range of –15V to +15V when operated with ±15V supplies. This rail-to-rail capability is guaranteed across its full specified supply range of ±4.5V to ±18V, enabling direct interface with legacy industrial and aerospace signal sources without external level shifting.

Does DG506ADN+T require external pull-up or pull-down resistors on address lines A0–A3?

No, DG506ADN+T does not require external pull-up or pull-down resistors on A0–A3. Its TTL/CMOS-compatible inputs draw only ±0.002µA at 25°C, and logic thresholds (VAL ≤0.8V, VAH ≥2.4V) are met directly by standard microcontroller GPIO outputs. External resistors are unnecessary unless noise immunity in high-EMI environments is required.

Is DG506ADN+T pin-compatible with the original Siliconix DG506A?

Yes, DG506ADN+T is fully pin-compatible with the original Siliconix DG506A. Both use the same 28-pin Wide SO package, identical pin assignments (including NC pins, address bits, EN, V+, V−, GND, D, and S1–S16), and share identical electrical behavior-making DG506ADN+T a direct drop-in replacement without layout changes.

What is the typical on-resistance matching between channels in DG506ADN+T?

DG506ADN+T exhibits ≤6% maximum variation in on-resistance between any two channels (ΔR_DS(ON)/R_DS(ON)AVE ≤6%). This tight matching ensures consistent gain and offset across all 16 channels in multi-channel instrumentation, critical for calibration stability and channel-to-channel accuracy in data loggers and ATE systems.

Can DG506ADN+T operate from a single +12V supply?

No, DG506ADN+T requires dual supplies (V+ and V−) and cannot operate from a single +12V rail. Its architecture mandates symmetric or asymmetric dual supplies ranging from ±4.5V to ±18V. For single-supply applications, consider alternatives such as the MAX4617 or ADG1414, which are explicitly designed for unipolar operation.
