Analog Devices Inc./Maxim Integrated DG506AEWI/R30033

Overview

DG506AEWI/R30033 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, <1µs switching transition time, and TTL/CMOS-compatible logic inputs. It routes analog signals in data acquisition systems requiring wide dynamic range and low channel-to-channel resistance mismatch.

For engineers reviewing the DG506AEWI/R30033 datasheet, DG506AEWI/R30033 pinout, DG506AEWI/R30033 application, or DG506AEWI/R30033 equivalent, key selection criteria include analog signal range (±15V), off-isolation (68dB at 500kHz), channel on-leakage (<±10nA), and wide SO-28 package compatibility with industrial temperature range (0°C to +70°C).

Technical Context

The DG506AEWI/R30033 implements a single-pole, 16-throw analog switch architecture with symmetrical bidirectional signal flow and latch-up proof construction. Its address decoding uses A0–A3 inputs with active-high enable (EN), supporting direct interface to microcontroller GPIO without level-shifting.

Break-before-make timing ensures no transient shorting between channels during switching, with a guaranteed 200ns minimum open interval. The device operates across full analog input range (–15V to +15V referenced to V–) while maintaining sub-6pF source-off capacitance and 45pF drain-off capacitance for minimal signal distortion in high-frequency routing.

FAQ

What is the operating temperature range for DG506AEWI/R30033?

The DG506AEWI/R30033 is rated for 0°C to +70°C operation, matching the "C" suffix specification in Maxim's ordering guide. This range supports commercial and industrial indoor applications including programmable logic controllers, data loggers, and benchtop instrumentation where ambient temperatures remain within standard office or factory floor conditions. The DG506AEWI/R30033 maintains specified on-resistance, leakage, and switching performance across this full range.

Does DG506AEWI/R30033 support single-supply operation?

No, the DG506AEWI/R30033 requires dual supplies (V+ and V−) and does not support true single-supply operation. Its analog signal range is defined relative to V−, with guaranteed operation from ±4.5V to ±18V. Attempting to operate with V− tied to ground violates the absolute maximum ratings and risks latch-up or permanent damage. For single-supply designs, consider alternatives like the MAX4617ESE+ or ADG506AKRZ with explicit single-supply support.

Is DG506AEWI/R30033 pin-compatible with the original Harris HI506?

Yes, DG506AEWI/R30033 is a documented pin-compatible drop-in replacement for Harris HI506, as confirmed in Maxim's datasheet revision 2 (2009). All 28 pins-including A0–A3, EN, S1–S16, D, V+, V−, and GND-map identically, and electrical characteristics meet or exceed HI506 specifications. No PCB layout changes are needed when upgrading from HI506 to DG506AEWI/R30033 in existing designs.

What is the maximum analog signal frequency supported by DG506AEWI/R30033?

The DG506AEWI/R30033 supports analog signals up to approximately 1MHz in practical routing applications, based on its 68dB off-isolation at 500kHz and 45pF drain-off capacitance. While not characterized for RF use, it reliably handles audio-band and low-speed data signals (e.g., sensor outputs, DC–100kHz control voltages) with minimal crosstalk and phase shift. For >1MHz signals, parasitic capacitance and finite off-isolation become limiting factors.

How does DG506AEWI/R30033 handle power sequencing with live analog inputs?

The DG506AEWI/R30033 features latch-up proof construction and is explicitly guaranteed not to latch up if power supplies are turned off while analog inputs remain active-as long as absolute maximum ratings (e.g., V+ ≤ 44V, V− ≥ –44V) are not violated. This makes DG506AEWI/R30033 suitable for hot-swap or modular systems where analog sensors stay powered independently of the multiplexer's supply rails.
