Product details
Overview
DG409DVZ from Renesas Electronics is a differential 4-channel CMOS analog multiplexer with bilateral signal switching, 100Ω max ON resistance at ±15V supplies, <250ns transition time, and operation across -40°C to +85°C. It serves as a drop-in replacement for DG509A in data acquisition and audio switching systems requiring low charge injection and split- or single-supply compatibility.
For engineers reviewing the DG409DVZ datasheet, DG409DVZ pinout, DG409DVZ application, or DG409DVZ equivalent, this page delivers verified specifications, TSSOP-16 package details, functional pin mapping, real-world use cases in Hi-Rel and sample-and-hold circuits, and two validated alternative parts with documented technical and application differences.
Technical Context
The DG409DVZ implements a TTL/CMOS-compatible 2-bit decode logic (A0/A1) with enable (EN) control to select one of four differential channel pairs (S1A/S1B through S4A/S4B), routing them to dual outputs DA and DB. Its silicon-gate process enables latch-up immunity and supports analog signal ranges from ±15V (bipolar) or 0–12V (single supply).
It features internal voltage reference for stable logic thresholds, low 20pC typical charge injection (CL = 10nF), and matched ON-resistance (<15Ω variation between channels), making it suitable for precision sampling where signal integrity and channel-to-channel consistency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (Max) | 100Ω at VD = ±10V, IS = −10mA - ensures minimal signal attenuation and gain error in precision analog paths |
| Transition Time (tTRANS) | <250ns - enables high-speed multiplexing up to ~1.5MHz without significant settling delay |
| Charge Injection | 20pC max - reduces hold-step error in sample-and-hold circuits, easing anti-aliasing filter design |
| Analog Signal Range | ±15V (bipolar) or 0–12V (single supply) - supports industrial sensor interfaces and audio line-level signals |
| Supply Voltage Range | V+ to V− ≤ 44V; ±5V to ±20V split or +5V to +34V single - accommodates wide-range power architectures |
| Logic Compatibility | TTL/CMOS - interfaces directly with microcontrollers, FPGAs, and legacy logic without level-shifting |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive under-hood environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4052ACPE+ | 16-pin PDIP only; higher 120Ω rDS(ON); 30pC charge injection; no TSSOP option | Preferred where through-hole assembly or legacy socket compatibility is required | Select when board space allows larger PDIP and higher ON resistance is acceptable for DC-coupled sensor mux |
| ADG409BRUZ | Same TSSOP-16 package; lower 85Ω rDS(ON); 15pC charge injection; wider −55°C to +125°C range | Better suited for extended-temperature or ultra-low-distortion applications | Choose when tighter ON-resistance matching or operation beyond +85°C is mandatory |
Compared with DG409DVZ, MAX4052ACPE+ offers legacy PDIP compatibility but sacrifices speed and charge performance, while ADG409BRUZ improves precision and temperature range in the same TSSOP footprint-making it ideal for next-gen instrumentation designs.

FAQ
What is the maximum analog signal voltage range supported by the DG409DVZ?
The DG409DVZ supports an analog signal range of ±15V under bipolar supply conditions (V+ = +15V, V− = −15V) and 0–12V under single-supply operation (V+ = 12V, V− = 0V). This range is defined by the absolute maximum rating of V+ to V− ≤ 44V and ensures full linear operation of the analog switches without clipping or distortion.
Does the DG409DVZ require external level-shifting when interfaced with 3.3V logic controllers?
No, the DG409DVZ does not require external level-shifting when used with 3.3V logic controllers. Its digital inputs (A0, A1, EN) are TTL/CMOS compatible with logic thresholds defined at VAL ≤ 0.8V and VAH ≥ 2.4V, ensuring reliable recognition of 3.3V logic HIGH/LOW states across its full operating temperature range.
Can the DG409DVZ be used in a single-supply configuration with V− tied to ground?
Yes, the DG409DVZ can operate in single-supply mode with V− tied to ground (0V) and V+ set between +5V and +34V. In this configuration, the analog input range is 0V to V+ − 1V (e.g., 0–12V at V+ = 12V), and all digital inputs remain fully compatible without modification.
What is the thermal resistance (θJA) of the DG409DVZ in its TSSOP package?
The DG409DVZ in its 16-lead TSSOP package has a typical junction-to-ambient thermal resistance (θJA) of 150°C/W, measured on an evaluation PCB in free air. This value informs thermal design margins-e.g., at 2mA supply current and 30mW dissipation, junction temperature rise is ~4.5°C above ambient under nominal conditions.
Is the DG409DVZ pin-compatible with the older DG509A series?
Yes, the DG409DVZ is a drop-in replacement for the DG509A series, sharing identical pinout, function mapping, and supply requirements. It improves upon the DG509A with lower ON resistance (<100Ω vs. ~120Ω), faster switching (<250ns vs. ~350ns), and reduced charge injection-requiring no PCB or firmware changes for upgrade.
