Renesas DG406DYZ

Overview

DG406DYZ from Intersil is a single 16-channel CMOS analog multiplexer with TTL/CMOS-compatible digital control, ±15V dual-supply operation, <100Ω ON-resistance, <300ns transition time, and -40°C to +85°C temperature range. It serves as a drop-in replacement for DG506A in data acquisition systems requiring low charge injection and bidirectional signal routing.

For engineers reviewing the DG406DYZ datasheet, DG406DYZ pinout, DG406DYZ application, or DG406DYZ equivalent, key selection criteria include its 28-pin SOIC package, 16:1 analog switch architecture, enable-controlled channel selection, and compatibility with ±15V or 12V single-supply operation.

Technical Context

The DG406DYZ integrates a 4-bit address decoder (A0–A3), active-high ENABLE input, and voltage reference for logic thresholds-enabling precise 1-of-16 channel selection. Its high-voltage silicon-gate process delivers latch-up immunity and supports up to ±22V analog signal swing with ±15V supplies.

All 16 switches are bilateral and symmetrical, exhibiting <5% rDS(ON) matching across channels and low variation over ±5V analog input range. Charge injection is limited to 40pC (typ), simplifying sample-and-hold design without external compensation.

FAQ

What is the maximum analog signal voltage supported by DG406DYZ?

DG406DYZ supports analog signals up to ±15V on the Sx and D pins when operated with ±15V supplies, enabling 30VP-P signal handling. Absolute maximum ratings specify V+ to V- ≤ 44V, and analog inputs must remain within (V-) –2V to (V+) +2V to avoid clamping diode conduction. This makes DG406DYZ suitable for industrial sensor interfaces and medical front-ends requiring wide dynamic range.

Does DG406DYZ require external level-shifting for TTL-compatible control inputs?

No, DG406DYZ does not require external level-shifting for TTL-compatible control inputs. Its digital inputs (A0–A3 and EN) are fully TTL and CMOS compatible, with guaranteed recognition of logic high at ≥2.4V and logic low at ≤0.8V across the full -40°C to +85°C operating range. This allows direct interfacing with standard microcontrollers, FPGAs, and logic families without additional circuitry.

How does the ENABLE pin function in DG406DYZ operation?

The ENABLE (EN) pin on DG406DYZ is an active-high digital input that globally controls all 16 analog switches. When EN is low, all switches are turned off regardless of address inputs, presenting high-impedance isolation (>69dB at 100kHz). When EN is high, the A0–A3 address bits determine which single channel connects D to the selected Sx terminal. This enables system-level power gating and fault-safe shutdown in safety-critical applications.

Can DG406DYZ operate from a single 12V supply instead of dual ±15V supplies?

Yes, DG406DYZ can operate from a single 12V supply (V+ = 12V, V- = 0V), supporting analog signal ranges from 0V to 12V. In this configuration, typical rDS(ON) is 90Ω (max 120Ω), transition time increases to 450ns (max), and charge injection remains low at 20pC (typ). The device maintains full functionality including address decoding and enable control, making it adaptable to cost-sensitive or space-constrained single-rail systems.

What is the thermal resistance (θJA) of the DG406DYZ SOIC package?

The DG406DYZ in its 28-lead SOIC package (M28.3) has a typical junction-to-ambient thermal resistance (θJA) of 75°C/W when mounted on a low effective thermal conductivity test board in free air. This value assumes standard JEDEC conditions and informs thermal design for continuous operation at maximum rated current (30mA per terminal) and ambient temperatures up to +85°C. Derating is recommended above 70°C ambient for sustained full-load operation.
