Product details
Overview
DG412DJ from Renesas Electronics is a monolithic quad SPST CMOS analog switch with complementary logic control (logic "0" = OFF, logic "1" = ON), 35 Ω max ON-resistance at ±15V analog range, 175 ns max tON, and ±20V dual-supply or 5–44V single-supply operation. It serves as a drop-in replacement for DG212 in precision signal routing applications such as data acquisition front-ends and battery-powered test instrumentation.
For engineers reviewing the DG412DJ datasheet, DG412DJ pinout, DG412DJ application, or DG412DJ equivalent, key selection criteria include its bilateral analog switching capability, low 5 pC typical charge injection, TTL/CMOS-compatible digital inputs, and guaranteed performance across –40°C to +85°C industrial temperature range.
Technical Context
The DG412DJ implements four independent, bidirectional SPST switches fabricated using a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Each switch supports analog signals up to ±15V with minimal rDS(ON) variation over voltage and temperature.
Its logic polarity differs from DG411 (DG412 uses positive logic: logic "1" turns switch ON), enabling direct interface with standard microcontroller GPIOs without level-shifting. The VL pin provides dedicated logic reference, decoupling digital thresholds from V+ and V− rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (max) | 35 Ω - Ensures minimal signal attenuation and gain error in precision analog paths at ±15V signal swing. |
| Turn-on time (max) | 175 ns - Enables reliable multiplexing of audio-band and medium-speed data signals (e.g., 1 MSPS sampling). |
| Analog signal range | ±15V (dual supply) or 0–12V (single supply) - Supports rail-to-rail analog routing in industrial sensor interfaces and power supply monitoring. |
| Charge injection (typ) | 5 pC - Reduces settling errors in sample-and-hold and switched-capacitor circuits without requiring large hold capacitors. |
| OFF isolation (typ) | 68 dB at 1 MHz - Provides effective channel-to-channel crosstalk suppression in multi-channel data acquisition systems. |
| Supply range | ±5V to ±20V dual or +5V to +44V single - Allows flexible integration into mixed-signal systems with varying supply domains. |
| Logic compatibility | TTL/CMOS - Direct interfacing with 3.3V/5V microcontrollers and FPGAs without external level translators. |
Pinout & Package
Package: 16-lead PDIP (plastic dual-in-line), JEDEC MS-001-BB, body width 0.300 inch, lead pitch 0.100 inch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; logic "1" ≥2.4V enables corresponding switch; referenced to VL, not V+ or GND. |
| 2, 15, 10, 7 | D1–D4 | Drain (output) terminals; bidirectional - may serve as input or output depending on signal flow direction. |
| 3, 14, 11, 6 | S1–S4 | Source (input) terminals; matched impedance and capacitance to D pins for symmetrical AC performance. |
| 4 | V− | Negative supply rail; must be connected for dual-supply operation; sets lower bound of analog signal range. |
| 5 | GND | Logic ground reference; separate from analog power grounds to minimize digital noise coupling into analog paths. |
| 12 | VL | Logic supply reference; requires stable 5V for TTL-compatible thresholds; isolates logic threshold from V+/V− variations. |
| 13 | V+ | Positive supply rail and substrate connection; sets upper bound of analog signal range and powers internal circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral SPST switching | Four fully symmetric, bidirectional analog paths enable flexible signal routing in both directions without polarity constraints. |
| Low charge injection (5 pC typ) | Minimizes voltage step errors during switch transitions in sample-and-hold and precision ADC driver stages. |
| High OFF isolation (68 dB) | Reduces unwanted signal coupling between channels in 16-channel multiplexers built from multiple DG412DJ units. |
| Wide supply flexibility | Operates from ±5V to ±20V or +5V to +44V - simplifies design in systems with legacy ±15V op-amp rails or modern 24V industrial supplies. |
| Latch-up immunity | Epitaxial layer prevents destructive latch-up under transient overvoltage or ESD events per JEDEC JESD78. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612CPD+ | Higher ON-resistance (45 Ω max), slower tON (250 ns max), no VL pin - logic referenced to V+. | Less suitable for precision low-offset sample-and-hold; better for cost-sensitive general-purpose routing where speed <100 kHz. | Select MAX4612CPD+ only if VL pin independence is unnecessary and 45 Ω rDS(ON) is acceptable in system gain budget. |
| ADG412BNZ | Identical pinout and logic polarity; lower typical charge injection (3 pC), but narrower supply range (±16.5V max vs ±20V). | Preferred for ultra-low-glitch S&H; unsuitable for 40VPP signal handling in high-voltage industrial monitoring. | Choose ADG412BNZ when minimizing charge injection dominates over maximum signal swing requirements. |
Compared with MAX4612CPD+ and ADG412BNZ, DG412DJ uniquely balances ±20V analog range, 35 Ω ON-resistance, and dedicated VL reference - making it optimal for industrial data acquisition where supply headroom and logic interface robustness are critical.

FAQ
What is the logic polarity of DG412DJ compared to DG411DJ?
The DG412DJ uses positive logic: a logic "1" (≥2.4V) turns each switch ON, whereas DG411DJ uses negative logic (logic "0" ≤0.8V turns switch ON). This difference is explicitly defined in the truth table on page 2 of the FN3282 datasheet. DG412DJ's logic polarity allows direct connection to standard microcontroller GPIOs without inversion logic, simplifying firmware control in systems using the DG412DJ.
Can DG412DJ operate from a single +12V supply?
Yes, DG412DJ supports single-supply operation from +5V to +44V. When using +12V, connect V+ (pin 13) to +12V, V− (pin 4) to 0V (ground), and VL (pin 12) to +5V for TTL-compatible logic thresholds. The analog signal range becomes 0V to +12V, and rDS(ON) rises to 80 Ω max (per page 5 electrical specs), which remains suitable for most general-purpose switching applications.
What is the purpose of the VL pin on DG412DJ?
The VL pin on DG412DJ provides a dedicated logic reference voltage, typically +5V, independent of V+ and V−. This ensures consistent TTL/CMOS-compatible input thresholds (logic "0" ≤0.8V, logic "1" ≥2.4V) regardless of analog supply rail fluctuations. It decouples digital control reliability from analog power domain variations - a key advantage over switches that tie logic thresholds directly to V+.
Does DG412DJ require external protection diodes for overvoltage on analog pins?
No, DG412DJ includes internal clamp diodes on all S and D pins. Per Absolute Maximum Ratings (page 4), analog signals exceeding V+ or V− are clamped, provided forward diode current is limited to ≤30 mA. For robust protection beyond this limit - e.g., in industrial I/O with ±30V transients - external series resistors (e.g., 1 kΩ) are recommended to keep clamp current within spec.
Is DG412DJ pin-compatible with the older DG212 series?
Yes, DG412DJ is a drop-in replacement for DG212, sharing identical 16-pin PDIP package (E16.3), pinout, and logic polarity. As stated on page 1 of FN3282, "The DG411 series monolithic CMOS analog switches are drop-in replacements for the popular DG211 and DG212 series devices." Performance improvements - including lower ON-resistance (<35 Ω vs ~60 Ω), faster switching (175 ns vs ~300 ns), and reduced charge injection - are achieved without PCB layout changes.
