Renesas DG407DYZ

Overview

DG407DYZ from Intersil is a differential 8-channel CMOS analog multiplexer with ±15V dual-supply operation, 100Ω max ON-resistance, 300ns max transition time, and TTL/CMOS-compatible logic inputs. It serves as a drop-in replacement for DG507A in data acquisition systems requiring bidirectional signal routing with low charge injection and high channel-to-channel matching.

For engineers reviewing the DG407DYZ datasheet, DG407DYZ pinout, DG407DYZ application, or DG407DYZ equivalent, key selection criteria include its differential 1-of-8 switching architecture, SOIC-28 package, -40°C to +85°C operating range, and compatibility with ±15V or single 12V supply configurations.

Technical Context

The DG407DYZ implements a dual-tier analog multiplexing architecture with two independent 8-channel banks (A and B), each sharing common address lines A0–A2 and enable (EN) but featuring separate drain terminals DA and DB. Its internal decode logic selects one pair of matched switches (e.g., S1A/S1B) simultaneously, enabling true differential signal routing without external pairing logic.

It uses a high-voltage silicon-gate CMOS process to achieve 44V absolute maximum V+–V− rating, latch-up immunity via epitaxial isolation, and stable rDS(ON) over ±5V analog input range. Charge injection is minimized to 40pC typical (±10V, CL=1nF), supporting precision sample-and-hold and medical instrumentation applications.

FAQ

What is the maximum analog signal voltage range supported by the DG407DYZ?

The DG407DYZ supports a maximum analog signal range of ±10V when operated from ±15V supplies, and 0V to 12V with a single 12V supply. Its 44V absolute maximum V+–V− rating allows safe handling of 30VP-P signals, making it suitable for industrial ±10V I/O standards. The DG407DYZ maintains low rDS(ON) variation across this full range, ensuring consistent gain accuracy.

Does the DG407DYZ require external pull-up resistors on its address or enable pins?

No, the DG407DYZ does not require external pull-up resistors. Its A0–A2 and EN inputs are TTL/CMOS-compatible with guaranteed VIH ≥2.4V and VIL ≤0.8V, and input leakage is limited to ±1µA across temperature. Internal biasing ensures reliable logic thresholds without external components, simplifying PCB layout and reducing BOM count for the DG407DYZ.

How does the DG407DYZ handle charge injection in sample-and-hold circuits?

The DG407DYZ minimizes charge injection to 40pC typical (±10V, CL=1nF), significantly reducing hold-mode voltage step errors. This performance, combined with low rDS(ON) matching (<5%), allows direct integration into precision sample-and-hold stages without additional correction circuitry. In medical instrumentation using the DG407DYZ, this enables sub-12-bit settling accuracy within 500ns.

Can the DG407DYZ operate reliably at -40°C ambient temperature?

Yes, the DG407DYZ is fully specified and tested over -40°C to +85°C. Electrical parameters including rDS(ON), leakage currents, and switching times are characterized across this range, with no derating required. Its epitaxial silicon-gate process ensures latch-up immunity and stable performance in cold-start industrial environments where the DG407DYZ is commonly deployed.

What is the purpose of the NC pins on the DG407DYZ SOIC package?

The DG407DYZ has NC pins at positions 2, 3, 13, and 14 - these pins have no internal connection and must remain unconnected in the PCB layout. Leaving them floating or tying them to ground/V+ risks parasitic coupling or unintended current paths. Proper handling of these NC pins is essential for maintaining signal integrity and meeting EMC requirements in systems using the DG407DYZ.
