Product details
Overview
DG401CJ from Maxim Integrated is a dual, high-speed, single-pole/single-throw (SPST) analog switch optimized for precision signal routing in bipolar or single-supply systems. It features 20Ω typical on-resistance, 2Ω maximum on-resistance matching between channels, 15pC maximum charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling rail-to-rail analog signal switching in test equipment and sample-and-hold circuits.
For engineers reviewing the DG401CJ datasheet, DG401CJ pinout, DG401CJ application, or DG401CJ equivalent, key selection criteria include guaranteed on-resistance flatness (≤3Ω), low off-leakage (<5nA at +85°C), sub-150ns turn-on time, TTL/CMOS logic compatibility, and 16-pin plastic DIP packaging for through-hole prototyping and industrial control interfaces.
Technical Context
The DG401CJ implements a silicon-gate CMOS process with substrate tied to V+, supporting bidirectional analog conduction and rail-to-rail signal handling across its full ±15V analog range. Its logic interface accepts 0.8V/2.4V thresholds with VL = +5V, ensuring robust TTL compatibility independent of supply voltage magnitude.
Switching is controlled by two independent digital inputs (IN1, IN2), each driving one SPST channel (S1/D1 and S2/D2). The device guarantees break-before-make timing only in DG403 variants - DG401CJ has no internal interlock; channel states are fully independent and non-overlapping by design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG401BRZ | Higher on-resistance (35Ω max), wider temp range (−40°C to +85°C), SOIC-16 package only | Lacks 16-pin DIP option; higher rDS(ON) increases gain error in precision DC paths | Select when surface-mount assembly is required and 35Ω rDS(ON) is acceptable for system accuracy budget |
| TS5A23157DCKR | Lower voltage rating (5.5V max), smaller 6-pin SC70 package, 0.9Ω rDS(ON) but limited to single-supply 1.65–5.5V operation | Not suitable for ±15V or high-voltage signal routing; intended for portable low-voltage logic-level switching | Choose only for battery-powered 3.3V/5V systems where ultra-low on-resistance outweighs voltage range limitations |
Compared with ADG401BRZ and TS5A23157DCKR, DG401CJ uniquely supports ±20V operation in a through-hole DIP package with guaranteed 2Ω channel matching and <5nA leakage at +85°C - making it irreplaceable for high-reliability, high-voltage, temperature-stable analog multiplexing.

FAQ
What is the maximum analog signal voltage range supported by the DG401CJ?
The DG401CJ supports analog signals from V− to V+, with absolute maximum ratings of −15V to +15V when operated at ±15V supplies. Its rail-to-rail capability allows full-swing signal handling without clipping, and the device remains functional with analog voltages extending to the supply rails - confirmed in the Electrical Characteristics table under VANALOG (±15V).
Does the DG401CJ require a separate logic supply voltage (VL), and what happens if VL is omitted?
Yes, DG401CJ requires VL = +5V for guaranteed TTL compatibility. If VL is unconnected or set outside +4.7V to +5.3V, logic thresholds shift and may cause erratic switching or increased input current. The datasheet specifies VL must be tied to +5V - not V+ or GND - to maintain 0.8V/2.4V input thresholds across temperature and supply variations.
Can the DG401CJ be used with a single +24V supply instead of dual ±15V supplies?
Yes, DG401CJ operates from a single +10V to +30V supply. When using +24V, connect V+ to +24V, V− to GND, VL to +5V, and GND to system ground. Analog signals can swing from 0V to +24V. This configuration is explicitly validated in the Absolute Maximum Ratings and Electrical Characteristics sections, including on-resistance and leakage data at V+ = +24V, V− = 0V.
What is the thermal derating behavior of the DG401CJ in its 16-pin plastic DIP package?
In the 16-pin plastic DIP package, DG401CJ has a thermal derating factor of 10.53mW/°C above +70°C ambient. Its maximum continuous power dissipation is 842mW at TA = +70°C. This linear derating ensures safe operation up to its rated +70°C operating temperature - a value confirmed in the Absolute Maximum Ratings table and validated by JEDEC-standard thermal testing.
Is the DG401CJ pin-compatible with older industry-standard DG401 variants?
Yes, DG401CJ is a plug-in upgrade for industry-standard DG401 devices, retaining identical pinout, footprint, and logic interface. It improves on legacy versions with tighter on-resistance matching (2Ω vs. 5Ω), lower charge injection (15pC vs. 25pC), and reduced off-leakage (<5nA vs. 25nA at +85°C), all without PCB layout changes.
