Product details
Overview
DG403CJ+ from Maxim Integrated is a dual, single-pole/double-throw (SPDT) high-speed analog switch with two normally open and two normally closed channels, designed for precision signal routing in bipolar or single-supply systems. It features 20Ω typical on-resistance, 2Ω maximum on-resistance matching between channels, 3Ω maximum on-resistance flatness over ±15V signal range, and 15pC maximum charge injection - enabling low-distortion sampling in test equipment and military radios.
For engineers reviewing the DG403CJ+ datasheet, DG403CJ+ pinout, DG403CJ+ application, or DG403CJ+ equivalent, key selection criteria include guaranteed rail-to-rail analog signal handling (±15V), sub-150ns turn-on time, <5nA off-leakage at +85°C, TTL/CMOS logic compatibility, and 16-pin plastic DIP package with verified pin mapping for S1/S2/S3/S4, D1–D4, IN1/IN2, V+/V−, VL, and GND.
Technical Context
The DG403CJ+ implements a silicon-gate CMOS architecture optimized for bidirectional analog conduction with matched channel performance. Its break-before-make switching action (10–20ns delay) prevents momentary shorting during state transitions, and internal substrate connection to V+ ensures stable operation across wide supply ranges.
It supports dual-supply operation from ±4.5V to ±20V or single-supply operation from +10V to +30V, with rail-to-rail analog signal capability (V− to V+). Logic control is referenced to VL = +5V, maintaining TTL compatibility regardless of analog supply voltage - critical for mixed-voltage system interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 30Ω max - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Match | 2Ω max - enables accurate differential signal switching without channel-induced imbalance |
| On-Resistance Flatness | 3Ω max over ±10V - maintains consistent gain and linearity across full analog input range |
| Charge Injection | 15pC max - limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy |
| Off-Leakage Current | <5nA at +85°C - prevents DC error accumulation in high-impedance sensor or timing circuits |
| Switching Time (tON/tOFF) | 150ns / 100ns max - supports >5MHz multiplexed signal acquisition in automated test systems |
| Supply Range | ±4.5V to ±20V or +10V to +30V - allows direct integration with legacy ±15V op-amp rails or modern single-rail supplies |
Pinout & Package
Package: 16-pin plastic DIP (0°C to +70°C operating range, JEDEC MS-001 standard).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | D1, D4 | Drain terminals - bidirectional analog outputs routed to external circuitry |
| 3, 6 | D2, D3 | Drain terminals - second pair of analog outputs supporting dual SPDT configuration |
| 9, 4, 5, 16 | S1–S4 | Source terminals - analog inputs tied to common signal sources or sensors |
| 10, 15 | IN1, IN2 | Digital control inputs - TTL/CMOS-compatible logic signals selecting NO/NC states per switch |
| 11 | V+ | Positive supply - connected to substrate; sets upper analog rail and powers internal logic |
| 14 | V− | Negative supply - sets lower analog rail; must be ≤44V below V+ for safe operation |
| 12 | VL | Logic supply - fixed at +5V to ensure reliable digital interface regardless of analog supply voltage |
| 13 | GND | Ground reference - provides return path for logic currents and stabilizes bias points |
| 2, 7 | N.C. | Not internally connected - no electrical function; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous conduction from V− to V+ - eliminates clipping in ±15V instrumentation front-ends |
| Guaranteed on-resistance matching | ≤2Ω difference between paired switches - essential for balanced modulator/demodulator designs |
| Low charge injection (15pC max) | Minimizes hold-mode voltage step in sample-and-hold circuits - preserves 12-bit+ resolution |
| Bipolar and single-supply flexibility | Operates identically across ±4.5V–±20V or +10V–+30V - simplifies power architecture in mixed-signal systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG403BRZ | Higher 35Ω max rDS(ON); 25pC max charge injection; operates up to +85°C only | Limited to commercial-grade industrial systems; less suitable for military temp-range or low-glitch sampling | Prefer DG403CJ+ when rail-to-rail ±15V operation, <5nA leakage at +85°C, or 15pC charge injection are required |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V); 0.9Ω typical rDS(ON); 12ns switching; no bipolar support | Targeted at low-voltage portable audio/video routing - incompatible with ±15V signal chains | Select DG403CJ+ for legacy ±15V infrastructure, high-voltage signal integrity, or extended temperature reliability |
Compared with ADG403BRZ and TS5A23157DGSR, the DG403CJ+ uniquely delivers guaranteed bipolar supply operation, military-grade temperature range (0°C to +70°C in plastic DIP), and tighter parametric guarantees on leakage, matching, and flatness - making it irreplaceable in precision test and defense applications where signal fidelity and supply flexibility are non-negotiable.

FAQ
What is the operating temperature range for the DG403CJ+?
The DG403CJ+ is rated for 0°C to +70°C operation, as confirmed by its "C" grade designation and ordering information specifying "DG403CJ" with plastic DIP packaging. This range is validated across all key parameters including on-resistance match, leakage current, and switching time - ensuring reliable performance in commercial and industrial control systems without derating.
Does the DG403CJ+ support single-supply operation?
Yes, the DG403CJ+ supports single-supply operation from +10V to +30V, as explicitly stated in the Electrical Characteristics table and Applications Information section. In this mode, analog signals swing rail-to-rail from ground to V+, and VL must still be tied to +5V to maintain TTL-compatible logic thresholds - enabling drop-in use in systems lacking negative supplies.
What is the function of the VL pin on the DG403CJ+?
The VL pin on the DG403CJ+ is the dedicated logic supply input, required to be connected to +5V to ensure TTL/CMOS-compatible logic thresholds regardless of analog supply voltage. It decouples digital interface requirements from analog rail voltages - allowing the DG403CJ+ to operate correctly with ±15V analog supplies while accepting standard 0V/5V control signals.
How many analog switches does the DG403CJ+ contain, and what is their configuration?
The DG403CJ+ contains four independent analog switches arranged as two SPDT sections: Switches 1 & 2 form one dual SPDT (S1/D1/D2), and Switches 3 & 4 form another (S3/D3/D4). Each SPDT has one normally open and one normally closed path, enabling true break-before-make signal routing - a core feature confirmed in the Functional Diagrams and Truth Tables section.
Is the DG403CJ+ pin-compatible with older DG403 variants?
Yes, the DG403CJ+ maintains identical pinout and functionality with prior DG403 versions in the same 16-pin DIP package, as confirmed by the "Plug-In Upgrade for Industry-Standard DG401/DG403/DG405" feature statement and matching Pin Configurations diagrams. No PCB changes are required when upgrading from legacy DG403 devices to DG403CJ+.
