Product details
Overview
DG411CJ+ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It delivers 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling use in sample-and-hold circuits and military radios requiring rail-to-rail analog handling.
For engineers reviewing the DG411CJ+ datasheet, DG411CJ+ pinout, DG411CJ+ application, or DG411CJ+ equivalent, key selection criteria include guaranteed on-resistance matching (≤3Ω), flatness over signal range (Δ4Ω), TTL/CMOS logic compatibility, and ESD tolerance ≥2000V per Method 3015.7.
Technical Context
The DG411CJ+ implements four independent NC SPST switches fabricated using a 44V silicon-gate process, supporting bidirectional conduction with matched channel RDS(ON). Its control logic accepts TTL/CMOS-compatible inputs referenced to VL (typically +5V), while analog terminals handle rail-to-rail signals up to ±15.5V with clamping diodes.
Switching performance is characterized by tON ≤145ns and tOFF ≤100ns under ±15V supplies, with break-before-make timing validated only for DG413 - confirming DG411CJ+ uses simultaneous make/break topology. Off-isolation exceeds 68dB and crosstalk remains below –85dB at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) configuration - all four switches conduct when logic input is low. |
| RDS(ON) Max | 45Ω at ±15V, +25°C - ensures minimal signal attenuation in audio and test equipment signal paths. |
| RDS(ON) Match | ≤3Ω max between channels - critical for multi-channel instrumentation where gain/phase tracking matters. |
| Charge Injection | ≤10pC - limits voltage glitch in sample-and-hold and ADC front-end applications. |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sensor interfaces and battery-operated systems. |
| Supply Range | ±4.5V to ±20V (bipolar) or +10V to +30V (single) - supports industrial and military power architectures. |
| ESD Rating | ≥2000V per Method 3015.7 - enables robust handling in manufacturing and field-deployed guidance systems. |
Pinout & Package
DG411CJ+ is housed in a 16-pin plastic DIP package (package code P16-1), with through-hole mounting and 0.300" wide body. Pin 1 is located at the top-left corner when viewed from the top with notch or dot orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 9, 12 | S1–S4, GND, S4, S3, S2 | Source terminals for each SPST switch and ground reference - S pins are analog return paths; GND is digital logic ground. |
| 2, 11, 13 | V−, V+, D2 | Negative supply input, positive supply input, and drain terminal for second switch - V+ connects to substrate; V− and V+ define analog signal swing. |
| 5, 6, 7, 8, 10, 14–16 | D4, IN4, IN3, D3, VL, IN1, IN2, D1 | Drain outputs and logic inputs - IN1–IN4 control respective switches; VL sets logic threshold (TTL/CMOS compatible at +5V). |
Key Features
| Feature | Design Value |
|---|---|
| Plug-in upgrade for legacy DG411 | Pin- and function-compatible replacement with improved RDS(ON) match and leakage - no PCB redesign required. |
| Rail-to-rail signal handling | Supports analog inputs from V− to V+ - enables full utilization of supply rails in audio routing and heads-up displays. |
| Low power consumption | 35µW max - extends battery life in portable test equipment and handheld military radios. |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V thresholds with VL = +5V - simplifies interface to FPGA, microcontroller, and ASIC control buses. |
| Guaranteed RFLAT(ON) | Δ4Ω max across full analog range - maintains consistent gain and linearity in precision measurement front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | 44V abs max rating; 35Ω RDS(ON); 10pC charge injection; but only rated to +85°C industrial temp range. | Not qualified for extended temperature military use; lacks 2000V ESD rating per Method 3015.7. | Select ADG411BRZ only for commercial-grade systems where cost sensitivity outweighs ruggedness requirements. |
| TS5A23157DGSR | Lower voltage: 5.5V max; 0.9Ω RDS(ON); 12pC charge injection; 1.65V–5.5V logic compatible. | Unsuitable for ±15V signal routing; limited to low-voltage consumer electronics and portable devices. | Choose TS5A23157DGSR only for battery-powered 3.3V systems needing ultra-low on-resistance, not for DG411CJ+'s high-voltage industrial role. |
Compared with ADG411BRZ and TS5A23157DGSR, DG411CJ+ uniquely supports ±20V analog operation, guarantees sub-5nA leakage at +85°C, and meets MIL-derivative ESD robustness - making it irreplaceable in guidance systems and military comms where signal fidelity and environmental resilience are non-negotiable.

FAQ
What is the operating temperature range for DG411CJ+?
DG411CJ+ is specified for 0°C to +70°C operation, matching its "C" grade designation. This range covers commercial and industrial applications including PBX systems and test equipment, but excludes extended-temperature variants like DG411DJ (–40°C to +85°C) or DG411AK (–55°C to +125°C). Thermal derating applies above +70°C per the 10.53mW/°C dissipation limit in the 16-pin DIP package.
Does DG411CJ+ support single-supply operation?
Yes, DG411CJ+ supports single-supply operation from +10V to +30V, with V− tied to ground. In this mode, analog signals swing from 0V to V+, and VL must be set to +5V for TTL compatibility. On-resistance increases slightly versus bipolar operation, and switching times lengthen - e.g., tON rises to 175ns max at +12V per datasheet Section 4.
How does DG411CJ+ differ from DG412CJ+ and DG413CJ+?
DG411CJ+ is normally closed (NC), DG412CJ+ is normally open (NO), and DG413CJ+ integrates two NC and two NO switches. All share identical electrical specs (RDS(ON), leakage, charge injection), pinout, and package. The functional difference lies solely in default switch state - DG411CJ+ conducts at logic low, making it ideal for fail-safe hold paths in sample-and-hold circuits.
Is DG411CJ+ pin-compatible with older DG411 variants?
Yes, DG411CJ+ is a plug-in upgrade for legacy DG411 devices in the same 16-pin DIP package. It retains identical pinout, logic behavior, and footprint while improving RDS(ON) matching (≤3Ω vs. older 5Ω spec), leakage (<5nA vs. 10nA), and ESD tolerance (2000V vs. unspecified). No layout changes are needed for drop-in replacement.
What logic voltage should be applied to VL on DG411CJ+?
VL must be set to +5V for TTL-compatible operation, ensuring proper recognition of 0.8V low and 2.4V high logic thresholds. If CMOS-level inputs are used, VL may be tied to V+, but this requires verifying logic high voltage compliance with the controller's output swing. The DG411CJ+ datasheet specifies performance only for VL = +5V in all electrical characteristics tables.
