Product details
Overview
DG408DVZ from Renesas Electronics is a single 8-channel CMOS analog multiplexer with TTL/CMOS-compatible digital decode logic, 100Ω max ON resistance at 25°C, <250ns transition time, and ±15V analog signal range. It operates from single +5V to +34V or split ±5V to ±20V supplies and serves as a drop-in replacement for DG508A in data acquisition and audio switching systems.
For engineers reviewing the DG408DVZ datasheet, DG408DVZ pinout, DG408DVZ application, or DG408DVZ equivalent, key selection criteria include its TSSOP-16 Pb-free package, low charge injection (20pC typ), EN-controlled channel enable/disable, and guaranteed rDS(ON) matching (<15Ω) across all eight channels under bipolar supply conditions.
Technical Context
The DG408DVZ implements an integrated silicon-gate CMOS process with epitaxial layer latch-up protection, enabling robust operation across -40°C to +85°C. Its digital decoder accepts three address bits (A0–A2) and an active-low EN input to select one of eight bidirectional analog channels.
Each switch features matched source-drain conduction, low OFF capacitance (26pF typ at drain), and rail-to-rail analog signal handling up to ±15V with minimal rDS(ON) variation over the full input range - critical for precision sample-and-hold and multiplexed sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 100Ω at 25°C - ensures minimal signal attenuation and gain error in precision DC-coupled paths |
| Transition Time (tTRANS) | <250ns - supports multiplexing rates up to ~2MHz without significant settling delay |
| Charge Injection | 20pC typical - reduces hold capacitor voltage step error in sample-and-hold circuits |
| Analog Signal Range | ±15V with ±15V supplies - enables direct interfacing with industrial ±10V sensor outputs |
| Supply Range | Single +5V to +34V or split ±5V to ±20V - accommodates legacy and high-voltage industrial rails |
| Logic Compatibility | TTL/CMOS - allows direct connection to microcontrollers, FPGAs, and legacy logic without level shifters |
| OFF Isolation | -75dB at 100kHz - suppresses crosstalk between inactive channels in dense multiplexed systems |
Pinout & Package
Package: 16-lead TSSOP (M16.173), Pb-free, RoHS-compliant, 4.9mm × 4.5mm body, 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 A0 | Address bit 0 (LSB) | Selects channel index bit 0; driven by MCU GPIO or address bus line |
| 2 EN | Enable input (active-high) | Disables all switches when low; required for multi-mux synchronization |
| 3 V− | Negative supply terminal | Bias reference for analog switches; must be connected even in single-supply mode |
| 4–7, 9–12 S1–S8 | Source inputs (channels 1–8) | Bidirectional analog inputs; pin order matches binary address decoding (S1 = 000, S8 = 111) |
| 8 D | Drain (common output) | Single-ended analog output node; connects to ADC input or amplifier stage |
| 13 V+ | Positive supply terminal | Substrate bias and switch driver rail; sets upper analog voltage limit |
| 14 GND | Logic ground | Digital reference for EN/A0–A2; separate from analog return in mixed-signal layouts |
| 15 A2 | Address bit 2 (MSB) | Completes 3-bit channel selection; MSB determines S5–S8 vs S1–S4 group |
| 16 A1 | Address bit 1 | Mid-order address bit; used with A0/A2 to fully decode 8 channels |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral analog switching | Enables AC-coupled and bidirectional signal routing (e.g., sensor excitation and return) |
| Low rDS(ON) matching | <15Ω max difference between any two channels - preserves gain consistency across multiplexed channels |
| Split/single supply flexibility | Operates identically across ±15V, +12V, or +24V rails - simplifies BOM consolidation across product variants |
| Pb-free TSSOP package | M16.173 footprint compatible with standard reflow profiles - supports lead-free manufacturing compliance |
| Latch-up immunity | Epitaxial silicon-gate process eliminates destructive latch-up - critical for high-reliability industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | Higher typical rDS(ON) (120Ω), slower tTRANS (300ns), same TSSOP-16 package | Slightly reduced bandwidth and higher on-resistance drift with temperature | Preferred where ADI ecosystem integration or SPICE model availability is prioritized over speed/resistance |
| MAX4617ESE+ | Lower supply voltage ceiling (+20V max), no split-supply support, SOIC-16 only | Not suitable for ±15V industrial sensors; limited to single-supply ≤+20V systems | Chosen when cost sensitivity outweighs bipolar supply requirement and layout space permits SOIC |
Compared with ADG408BRUZ and MAX4617ESE+, DG408DVZ offers superior analog performance (lower rDS(ON), faster switching, better charge injection) and full ±20V split-supply operation - making it optimal for high-precision, wide-voltage industrial multiplexing where signal integrity is critical.

FAQ
What is the maximum analog signal voltage range supported by DG408DVZ?
The DG408DVZ supports an analog signal range of ±15V when operated with ±15V supplies, and 0V to +12V with a +12V single supply. Absolute maximum ratings allow V+ to V− up to 44V, but the usable linear analog range is bounded by the supply rails. This makes DG408DVZ suitable for interfacing with industrial ±10V sensors and legacy instrumentation without external level shifting.
Does DG408DVZ require external pull-up resistors on its address or enable pins?
No, DG408DVZ does not require external pull-up resistors. Its digital inputs (A0, A1, A2, EN) have TTL/CMOS-compatible thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and internal clamping diodes. Input leakage remains within ±10μA across temperature, allowing direct connection to microcontroller GPIOs or FPGA I/O banks without external biasing components.
Can DG408DVZ be used in a single-supply configuration with 0V ground reference?
Yes, DG408DVZ supports true single-supply operation down to +5V with V− tied to ground. In this mode, the analog input range is 0V to V+ − 1V (e.g., 0V to +11V at +12V supply), and logic inputs remain compatible with 0V/3.3V or 0V/5V systems. The device maintains <100Ω rDS(ON) and <250ns tTRANS under these conditions, as verified in the datasheet's single-supply test tables.
How does the charge injection specification of DG408DVZ impact sample-and-hold circuit design?
DG408DVZ specifies 20pC typical charge injection, measured with CL = 10nF and VS = 0V. In a sample-and-hold application, this results in a hold-step error of ΔV = Q/CL = 2mV - well within 12-bit (≈1.2mV) and acceptable for 14-bit (≈0.3mV) systems with minor trimming. Layout best practices (short traces, guard rings) further minimize parasitic coupling that could exacerbate this effect.
Is DG408DVZ pin-compatible with the legacy DG508A series?
Yes, DG408DVZ is a documented drop-in replacement for DG508A, sharing identical pinout, function mapping, and electrical interface across all 16 pins. It improves upon DG508A with lower ON resistance (<100Ω vs. 120Ω), faster switching (<250ns vs. 350ns), reduced charge injection, and latch-up immunity - all while maintaining full backward compatibility in existing PDIP, SOIC, and TSSOP layouts.
