Product details
Overview
DG411DJ+ 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 features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, rail-to-rail analog signal handling (±15V), and TTL/CMOS logic compatibility - enabling use in sample-and-hold circuits and military radio front-ends.
For engineers reviewing the DG411DJ+ datasheet, DG411DJ+ pinout, DG411DJ+ application, or DG411DJ+ equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω), low inter-channel RDS(ON) mismatch (3Ω max), ESD tolerance (2000V min), and operation across ±4.5V to ±20V or +10V to +30V supplies.
Technical Context
The DG411DJ+ implements four independent NC SPST switches fabricated using a 44V silicon-gate process. Each channel guarantees symmetric conduction bidirectionally, with on-resistance flatness specified over the full analog signal range (±15.5V) under bipolar supply conditions.
It supports dual-supply operation (±4.5V to ±20V) or single-supply operation (+10V to +30V), with VL pin configurable for TTL (5V) or CMOS-level logic interfacing. Switching times are tightly controlled: tON ≤ 150ns and tOFF ≤ 100ns at ±15V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | Quad NC SPST; 35Ω RDS(ON); 15pC charge injection; operates up to +36V but only ±20V bipolar | Higher charge injection limits use in high-resolution sample-and-hold; wider single-supply range suits industrial PLC I/O | Select ADG411BRZ when extended +36V single-supply operation is required and 15pC charge injection is acceptable |
| TS5A23157DGSR | Quad NC SPST; 0.9Ω RDS(ON); 3.3V logic only; max ±5.5V analog range; 12ns switching | Optimized for low-voltage portable audio; insufficient voltage rating for ±15V military or test gear | Select TS5A23157DGSR only for battery-powered consumer audio where rail-to-rail ±15V capability is not needed |
Compared with ADG411BRZ and TS5A23157DGSR, the DG411DJ+ uniquely balances ±20V bipolar operation, 10pC charge injection, and NC fail-safe behavior - making it the only option qualified for MIL-STD-883B environments and precision analog hold functions requiring sub-5nA leakage at +85°C.

FAQ
What is the maximum analog signal range supported by the DG411DJ+?
The DG411DJ+ supports a rail-to-rail analog signal range from V− to V+, with absolute maximum ratings of ±20V for bipolar operation and up to +30V for single-supply use. At ±15V supplies, the guaranteed usable analog range is ±15.5V - verified across the full −40°C to +85°C temperature range and critical for precision instrumentation and military radio signal chains where headroom directly impacts dynamic range.
Is the DG411DJ+ pin-compatible with the original DG411 series?
Yes, the DG411DJ+ is a plug-in upgrade for industry-standard DG411 devices in the 16-pin DIP package. Pin assignments, logic polarity, and functional behavior are identical - including NC configuration, IN/D/S terminal mapping, and VL/V+/V− supply connections. Performance improvements (e.g., lower leakage, tighter RDS(ON) match) require no PCB or firmware changes.
Does the DG411DJ+ require external protection diodes for overvoltage conditions?
No, external blocking diodes are optional. The DG411DJ+ includes internal ESD protection rated to 2000V per Method 3015.7, and its absolute maximum ratings (e.g., V+ ≤ 44V, V− ≥ −20V) define safe operating limits. However, if supply sequencing cannot be guaranteed (e.g., V− powered before V+), external diodes may be added - reducing analog range by ~1V but preserving DG411DJ+ functionality and leakage specs.
How does the DG411DJ+ perform at elevated temperatures?
The DG411DJ+ is characterized and 100% tested for off-leakage current at +85°C, guaranteeing <5nA. On-resistance increases predictably with temperature - rising ~20% from +25°C to +85°C at ±15V - but remains within Δ4Ω flatness spec. This validated high-temp behavior makes DG411DJ+ suitable for under-hood automotive modules and avionics subsystems where thermal stability is non-negotiable.
Can the DG411DJ+ operate from a single +12V supply?
Yes, the DG411DJ+ supports single-supply operation from +10V to +30V. When using +12V, connect V− to GND, set VL = +5V for TTL compatibility, and expect RDS(ON) ≈ 100Ω (typical) and tON/tOFF ~175ns/140ns. Analog signal range becomes 0V to +12V - confirmed in Electrical Characteristics tables and Typical Operating Curves (DG411-03, DG411-04).
