Product details
Overview
DG308ACJ+ from Maxim Integrated is a quad SPST analog switch with normally open (NO) configuration, designed for precision signal routing in mixed-signal systems. It delivers 60Ω typical on-resistance, <120ns turn-on time, and supports ±5V to ±20V dual supplies or +5V to +30V single supply, enabling use in test equipment front-ends and military radio channel selection.
For engineers reviewing the DG308ACJ+ datasheet, DG308ACJ+ pinout, DG308ACJ+ application, or DG308ACJ+ equivalent, key selection criteria include its 44V breakdown rating, CMOS-compatible logic inputs, low 10pC charge injection, and guaranteed operation from 0°C to +70°C in 16-pin plastic DIP packaging.
Technical Context
The DG308ACJ+ implements monolithic CMOS switch architecture with substrate-connected V+ pin, enabling rail-to-rail analog signal handling up to ±15V when biased with split supplies. Its four independent channels feature matched rDS(ON) tracking and low off-capacitance (11pF CS(OFF), 8pF CD(OFF)) for minimal crosstalk in high-frequency sample-and-hold paths.
Logic control inputs accept standard CMOS voltage thresholds (VIH ≥ 3.5V, VIL ≤ 1.1V at V+ = 15V), allowing direct interfacing with microcontrollers and FPGAs without level-shifting. The device maintains <100nA supply current over temperature and exhibits <100pA leakage at ±14V off-state blocking - critical for precision guidance system signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 4 independent SPST NO switches - enables simultaneous routing of four analog signals without interaction. |
| rDS(ON) Typ. | 60Ω at V+ = 15V, V− = −15V - ensures minimal signal attenuation and gain error in 50Ω–1kΩ impedance interfaces. |
| tON / tOFF Max | 200ns / 150ns - supports sampling rates up to 5MHz in automated test equipment scan paths. |
| Analog Range | ±15V - accommodates full-scale industrial sensor outputs and military-grade audio signals without clipping. |
| Breakdown Voltage | 44V - provides 30V peak-to-peak blocking margin, essential for fault-tolerant PBX line interface protection. |
| Charge Injection | 10pC - limits voltage glitch to <1mV on 0.01µF hold capacitors, meeting 12-bit sample-and-hold accuracy requirements. |
| Supply Range | +5V to +30V (single) or ±5V to ±20V (dual) - allows deployment in legacy 5V systems and modern high-voltage data acquisition rails. |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), JEDEC MS-001, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS-compatible digital control inputs - active-high logic turns corresponding switch ON (NO path closed). |
| 2, 7, 10, 15 | D1–D4 | Drain outputs - carry switched analog signal to downstream circuitry; rated for 20mA continuous current. |
| 3, 6, 11, 14 | S1–S4 | Source inputs - accept analog signals up to ±15V; symmetric with drains for bidirectional signal flow. |
| 4 | V− | Negative supply rail - must be connected to −5V to −20V (dual) or GND (single-supply mode). |
| 5 | GND | Signal reference and substrate tie - connects to system ground plane for noise immunity and ESD discharge path. |
| 12 | N.C. | No internal connection - left unconnected; no routing or thermal relief required on PCB. |
| 13 | V+ | Positive supply and substrate bias - connects to +5V to +30V (single) or +5V to +20V (dual); ties substrate to highest potential. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance matching | ≤15Ω max mismatch between channels - preserves amplitude consistency across multi-channel instrumentation front-ends. |
| Bipolar supply flexibility | Operates identically across ±5V, ±12V, and ±15V rails - eliminates need for separate BOM variants in mixed-voltage systems. |
| Ultra-low leakage | <100pA ID(OFF) at ±14V - prevents DC drift in high-impedance guidance sensor interfaces over 10-year field life. |
| Fast switching with low glitch | 10pC charge injection + 27pF CD(ON)+CS(ON) - reduces settling time to <500ns for 0.1% accuracy in 10-bit ADC sample clocks. |
| High off-isolation | 78dB at 500kHz - suppresses crosstalk between adjacent RF receive paths in military radio transceivers. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel, 35Ω rDS(ON), 16-lead SOIC; requires 3V–20V dual supply only - no single-supply support. | Better suited for high-density PCB layouts where channel count >4 is needed; unsuitable for +5V-only systems. | Select ADG408BRZ only if board space is constrained and dual-supply infrastructure already exists. |
| TS5A23157DCUR | 2-channel, 0.9Ω rDS(ON), 10-pin VSSOP; operates from 1.65V–5.5V - lacks ±15V analog range and 44V breakdown. | Optimized for portable battery-powered gear; cannot replace DG308ACJ+ in industrial/military analog signal chains. | Choose TS5A23157DCUR only for low-voltage, low-power consumer applications with sub-5V rails. |
Compared with ADG408BRZ and TS5A23157DCUR, the DG308ACJ+ uniquely balances high-voltage robustness (±15V range, 44V rating), quad-channel integration, and single/dual supply flexibility - making it irreplaceable in legacy test and defense platforms requiring proven reliability over extended temperature ranges.

FAQ
What is the maximum analog signal voltage the DG308ACJ+ can switch without damage?
The DG308ACJ+ supports analog signals from V− to V+, with absolute maximum ratings of +44V on V+ and −20V on V−. When operated with ±15V supplies, the safe analog range is −15V to +15V. Exceeding these limits risks permanent damage, as confirmed by Maxim's Absolute Maximum Ratings table. The DG308ACJ+ must never switch signals outside its powered supply rails.
Does the DG308ACJ+ support single-supply operation, and what are the trade-offs?
Yes, the DG308ACJ+ operates from +5V to +30V single supply, with GND as V−. Trade-offs include higher rDS(ON) (up to 150Ω vs. 60Ω in dual-supply mode) and slower switching (tON up to 200ns). These effects are documented in Maxim's Typical Operating Characteristics curves and Electrical Characteristics tables for DG308ACJ+.
Is the DG308ACJ+ pin-compatible with the DG309 series?
No - although both are quad SPST switches in identical 16-pin DIP packages, the DG308ACJ+ is normally open (NO) while DG309 is normally closed (NC). Their truth tables are inverted: IN = HIGH closes DG308ACJ+ but opens DG309. Swapping them without logic inversion causes functional failure in the target system.
What is the thermal resistance (θJA) of the DG308ACJ+ in its plastic DIP package?
The DG308ACJ+ in 16-pin plastic DIP has a junction-to-ambient thermal resistance (θJA) of 119°C/W, derived from its 842mW maximum power dissipation at TA = +70°C and 10.53mW/°C derating rate. This value is specified in the Absolute Maximum Ratings section of the DG308ACJ+ datasheet and validated across production lots.
Can the DG308ACJ+ be used in AC-coupled RF applications up to 10MHz?
Yes - the DG308ACJ+ exhibits 78dB off-isolation at 500kHz and maintains <1pF additional capacitance in the on-state. At 10MHz, insertion loss remains <0.5dB for 50Ω systems, as verified by Maxim's Typical Operating Characteristics plots and application note AN3926. Layout-dependent parasitics dominate above 5MHz, not the DG308ACJ+ itself.
