Product details
Overview
DG412CJ+ from Maxim Integrated is a quad, normally open (NO), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 150ns max tON, ±4.5V to ±20V dual-supply operation, and rail-to-rail analog signal handling up to ±15.5V - enabling use in battery-operated test equipment and military radio front-ends.
For engineers reviewing the DG412CJ+ datasheet, DG412CJ+ pinout, DG412CJ+ application, or DG412CJ+ equivalent, key selection criteria include guaranteed on-resistance matching (≤3Ω), low charge injection (≤10pC), ESD tolerance (≥2000V), and compatibility with TTL/CMOS logic levels across industrial temperature range (0°C to +70°C).
Technical Context
The DG412CJ+ implements four independent SPST switches with NO configuration, each controlled by a dedicated digital input (IN1–IN4). Its silicon-gate 44V process enables robust operation under ±20V supplies while maintaining low RDS(ON) flatness (Δ4Ω max) over the full analog signal range.
Switching is bidirectional with symmetrical on-resistance and low capacitance (CD(OFF) = 9pF, CS(OFF) = 9pF). Logic interface accepts 0.8V/2.4V thresholds (TTL/CMOS-compatible), and VL pin allows flexible logic supply referencing to either V+ or +5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 35Ω max at ±15V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Match (ΔRDS(ON)) | 3Ω max between channels - critical for matched gain/phase in multi-channel instrumentation |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces |
| Charge Injection | 10pC max - minimizes voltage glitch during switching in integrator and ADC input stages |
| Turn-On/Off Time | tON ≤150ns, tOFF ≤100ns at ±15V - supports fast multiplexing in communication and test systems |
| Analog Signal Range | ±15.5V with ±16.5V supplies - enables full rail-to-rail signal handling without clipping |
| ESD Tolerance | 2000V min per Method 3015.7 - enhances reliability in handling-sensitive production environments |
Pinout & Package
DG412CJ+ is housed in a 16-pin plastic DIP package (package code P16-1), through-hole mountable with 0.300" wide body and standard 0.1" pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 2, 15, 16) | Digital control inputs | Active-high TTL/CMOS-compatible logic; each enables one NO switch when high |
| S1–S4 (Pins 3, 4, 13, 14) | Source terminals | Low-impedance analog outputs; connected internally to D pins when switch is ON |
| D1–D4 (Pins 5, 6, 11, 12) | Drain terminals | High-impedance analog inputs; bidirectional conduction path with S pins |
| V+ (Pin 10) | Positive supply | Bipolar +15V or single +12V to +30V; also connects to substrate for latch-up immunity |
| V− (Pin 9) | Negative supply | Bipolar −15V or GND in single-supply mode; must be sequenced after V+ |
| GND (Pin 8) | Analog ground reference | Return path for leakage currents and substrate bias; separate from digital ground recommended |
| VL (Pin 7) | Logic supply | Set to +5V for TTL compatibility or tied to V+ for CMOS-level inputs |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPST NO configuration | Four independent, non-latching switches - simplifies discrete relay replacement and reduces board space vs. dual-package solutions |
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - eliminates level-shifting in ±15V op-amp circuits and audio line drivers |
| Guaranteed RFLAT(ON) ≤4Ω | Flat on-resistance across full signal swing - maintains consistent gain and THD in audio and instrumentation paths |
| Low power consumption | 35µW max at +25°C - extends battery life in portable test gear and handheld radios |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds with VL pin flexibility - interoperates directly with microcontrollers and FPGAs without level shifters |

FAQ
What is the maximum analog signal voltage range supported by DG412CJ+?
DG412CJ+ supports an analog signal range of ±15.5V when operated with ±16.5V supplies, and 0V to +12V with a +12V single supply. This rail-to-rail capability is enabled by its 44V silicon-gate process and internal clamping diodes - ensuring full dynamic range utilization without external level shifting in ±15V op-amp circuits.
Does DG412CJ+ require a separate logic supply voltage?
Yes, DG412CJ+ requires a dedicated VL pin (Pin 7) for logic interface. It must be connected to +5V for TTL compatibility or tied to V+ for CMOS-level inputs. This separation allows independent optimization of analog and digital supply domains - critical for noise-sensitive applications like sample-and-hold circuits where DG412CJ+ is commonly deployed.
Can DG412CJ+ be used in single-supply configurations?
Yes, DG412CJ+ operates from a single +10V to +30V supply by connecting V− (Pin 9) to ground. The device maintains full functionality including rail-to-rail analog signal handling (0V to V+), 35Ω max RDS(ON), and TTL/CMOS compatibility via the VL pin - making it suitable for portable test instruments and battery-powered communication systems where DG412CJ+ replaces dual-supply alternatives.
What is the thermal performance of DG412CJ+ in the 16-pin DIP package?
In its 16-pin plastic DIP package, DG412CJ+ has a power dissipation limit of 842mW at +70°C, derating by 10.53mW/°C above that temperature. This thermal profile supports continuous operation in enclosed test equipment enclosures and military radio chassis without forced air cooling - provided ambient temperature remains within the 0°C to +70°C specification range for DG412CJ+.
How does DG412CJ+ compare to the original DG412 in terms of leakage current?
DG412CJ+ improves off-leakage current to <5nA at +85°C - a 5× reduction versus earlier DG412 versions. This enhancement is confirmed in the Electrical Characteristics table and validated across temperature sweeps (Figure DG411-05). For applications like high-impedance sensor multiplexing or precision integrators, DG412CJ+ delivers measurably lower offset drift and longer hold times than legacy DG412 variants.
