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 and 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 handling in test equipment and military radios.
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 switching times, and compatibility with TTL/CMOS logic levels using a dedicated +5V VL supply.
Technical Context
The DG401CJ+ implements a silicon-gate CMOS process with substrate tied to V+, supporting bidirectional analog conduction and rail-to-rail signal switching across its full ±15V range. Its logic interface uses separate VL (typically +5V) and ground-referenced digital inputs, decoupling logic thresholds from analog supply rails.
Switching is controlled by two independent TTL/CMOS-compatible 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.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Lower rDS(ON) (0.9Ω typ), but requires ≥±5V dual supply; no VL pin - logic tied to V+ or V− | Better for low-voltage precision instrumentation; less suitable for mixed-supply systems with independent logic rails | Choose ADG1419BRUZ when ultra-low on-resistance and low THD are critical, and supply architecture permits integrated logic/analog rails. |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V); 0.9Ω rDS(ON); 30ns switching - optimized for portable low-voltage designs | Not rated for ±15V operation; unsuitable for industrial/military analog signal ranges beyond 5V | Choose TS5A23157DGSR for battery-powered audio or sensor interfaces where supply headroom is limited and speed outweighs voltage range. |
Compared with ADG1419BRUZ and TS5A23157DGSR, DG401CJ+ uniquely supports independent +5V logic (VL) alongside wide-range analog supplies (±20V), making it the only option among the three capable of robust rail-to-rail switching in mixed-signal systems requiring both high voltage tolerance and TTL/CMOS interoperability.

FAQ
What is the maximum analog signal voltage range supported by DG401CJ+?
DG401CJ+ supports analog signals from V− to V+ across its full specified supply range. With ±15V supplies, the signal range is −15V to +15V. Absolute maximum ratings allow V+ up to +44V relative to V−, but functional analog range remains bounded by the applied supply rails. DG401CJ+ maintains rail-to-rail conduction capability within these limits.
Does DG401CJ+ require a separate logic supply voltage, and why?
Yes, DG401CJ+ requires a dedicated VL pin, typically connected to +5V, to establish TTL/CMOS-compatible logic thresholds independent of analog supply voltages. This design allows reliable digital control even when V+ and V− operate at ±18V or +28V, ensuring noise margin and switching consistency across diverse power architectures.
How does DG401CJ+ handle charge injection in sample-and-hold applications?
DG401CJ+ guarantees ≤15pC maximum charge injection, measured with CL = 1.0nF and zero-source impedance. This low value minimizes hold-mode voltage step errors and reduces settling time in precision S/H circuits - a key parameter validated across temperature and signal range per Maxim's electrical characteristics table.
Is DG401CJ+ pin-compatible with older DG401 variants like DG401DJ?
Yes, DG401CJ+ shares identical 16-pin DIP pinout and functional mapping with DG401DJ and other DG401 variants in the same package. All share the same S1/D1/IN1/V+/VL/GND/V−/S2/D2/IN2 pin assignments and truth table behavior - enabling drop-in replacement where temperature and parametric requirements align.
What is the off-isolation performance of DG401CJ+, and how is it measured?
DG401CJ+ delivers 72dB minimum off-isolation at 1MHz, measured with RL = 100Ω and CL = 5pF per Figure 5 in the datasheet. This specification quantifies signal rejection from an enabled channel into a disabled channel, directly impacting crosstalk in multiplexed systems and validated under standard test conditions at +25°C.
