Product details
Overview
DG301ACJ+ from Maxim Integrated is a dual SPDT CMOS analog switch designed for precision signal routing in low-power, battery-operated systems. It features <50Ω on-resistance, ±15V analog signal range (V+ to V−), break-before-make switching, 150ns typical turn-on time, and TTL/CMOS-compatible control inputs - enabling reliable operation in portable instrumentation and programmable gain amplifiers.
For engineers reviewing the DG301ACJ+ datasheet, DG301ACJ+ pinout, DG301ACJ+ application, or DG301ACJ+ equivalent, key selection criteria include its 14-pin PDIP package, dual SPDT topology, single- or dual-supply flexibility (±5V to ±18V), low charge injection (12pC), and guaranteed performance across 0°C to +70°C.
Technical Context
The DG301ACJ+ implements monolithic CMOS switch architecture with latchup-proof construction and fully independent channel control. Its dual SPDT configuration supports two separate analog signal paths, each with break-before-make timing (50ns minimum interval) to prevent signal shorting during state transitions.
It operates with supply voltages from ±5V to ±18V (or +10V to +30V single-supply with V− tied to GND), maintaining analog signal integrity across the full V+ to V− range. Input logic thresholds are fixed at 0.8V (VIH) and 4.0V (VIL), ensuring robust compatibility with both TTL and CMOS drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports rail-to-rail analog signals without clipping when powered at ±15V. |
| On-Resistance (RDS(ON)) | <50Ω typ - ensures minimal signal attenuation and voltage drop in precision signal paths. |
| Turn-On Time (tON) | 150ns typ - enables fast multiplexing in sample/hold and data acquisition circuits. |
| Charge Injection | 12pC - limits output voltage glitch in high-impedance sampling nodes (e.g., S/H capacitors). |
| Off-Leakage Current | <1nA max (ID(OFF)/IS(OFF)) - preserves accuracy in µA-level current-sensitive applications. |
| Supply Voltage Range | ±5V to ±18V dual, or +10V to +30V single - allows flexible power architecture integration. |
| Logic Compatibility | TTL/CMOS - eliminates level-shifting requirements when interfacing with microcontrollers or FPGAs. |
Pinout & Package
Package: 14-lead plastic DIP (PDIP), 0.300" wide, through-hole mount. Pin 1 marked by notch or dot; pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D1 (Drain 1) | Analog output terminal of first SPDT switch; connects to load or downstream circuit. |
| 2 | S1 (Source 1) | Analog input/common terminal of first SPDT switch; shared between two outputs. |
| 3 | IN1 | Digital control input for first SPDT switch; logic high enables connection S1↔D1. |
| 4 | N.C. | No internal connection - must be left unconnected or grounded per layout best practice. |
| 5 | GND | Ground reference for digital logic and substrate bias; critical for noise immunity and leakage control. |
| 6 | V− | Negative supply rail; ties to −15V (dual) or 0V (single-supply mode); defines lower analog signal limit. |
| 7 | IN2 | Digital control input for second SPDT switch; independent of IN1 for asynchronous operation. |
| 8 | N.C. | No internal connection - must be left unconnected or grounded. |
| 9 | D2 | Analog output terminal of second SPDT switch; electrically isolated from D1 path. |
| 10 | S2 | Analog input/common terminal of second SPDT switch; independent signal path from S1. |
| 11 | N.C. | No internal connection - no internal bond wire; floating or grounded per PCB design rules. |
| 12 | N.C. | No internal connection - unused pad; avoid routing traces to this pin. |
| 13 | V+ | Positive supply rail; ties to +15V (dual) or +30V (single); defines upper analog signal limit. |
| 14 | N.C. | No internal connection - substrate/case tie point; typically connected to V+ per datasheet note. |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Switching | Guaranteed 50ns minimum interval prevents momentary shorting between D1/D2 paths during IN1/IN2 transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPE+ | Single SPST, 35Ω RDS(ON), 16-pin PDIP, ±20V rating, but lacks break-before-make. | Not suitable for SPDT routing or simultaneous channel isolation; requires two devices for dual SPDT function. | Select only if SPST topology suffices and lower on-resistance is prioritized over dual SPDT integration. |
| ADG1419BRUZ | Dual SPDT, 1.3Ω RDS(ON), 16-pin TSSOP, ±15V, but higher 35pC charge injection and no metal-can option. | Better for low-RON audio routing; less suitable for precision S/H due to higher charge injection. | Prefer for high-fidelity signal paths where on-resistance dominates; avoid where sub-15pC injection is mandatory. |
Compared with DG301ACJ+, MAX4617CPE+ offers lower on-resistance but requires external duplication for dual SPDT functionality, while ADG1419BRUZ delivers ultra-low RDS(ON) at the cost of triple the charge injection - making DG301ACJ+ optimal for battery-powered precision analog routing where integration, leakage, and injection are jointly constrained.

FAQ
What is the maximum supply voltage rating for DG301ACJ+?
The DG301ACJ+ supports dual-supply operation up to ±18V (36V total) and single-supply operation up to +30V (with V− tied to GND). Absolute maximum ratings specify V+ ≤ 44V for DG301A variants, but the DG301ACJ+ - as a C-grade, plastic DIP part - is rated for ±18V per the Electrical Characteristics table and Ordering Information. Exceeding these limits risks permanent damage.
Does DG301ACJ+ support break-before-make switching, and is it guaranteed?
Yes, DG301ACJ+ guarantees break-before-make operation with a minimum 50ns interval between turn-off of one switch and turn-on of the other within the same SPDT pair. This is explicitly tested and specified in the Break-Before-Make Interval parameter (tON − tOFF) under Dynamic Characteristics, ensuring no signal shorting during logic transitions.
Can DG301ACJ+ operate from a single +12V supply?
Yes, DG301ACJ+ supports single-supply operation: connect V− to GND and apply +12V to V+. The analog signal range becomes 0V to +12V, and logic thresholds remain compatible (VIH = 4.0V, VIL = 0.8V). Table 1 confirms functional operation at +10V to +30V, with on-resistance and switching times degrading only slightly at lower voltages.
What is the thermal performance of DG301ACJ+ in its 14-pin PDIP package?
In its 14-lead plastic DIP (J) package, DG301ACJ+ has a power dissipation limit of 470mW at +25°C, derating linearly by 6.5mW/°C above that temperature. At +70°C ambient, maximum allowable power drops to ~441mW. This aligns with its typical quiescent supply current of <0.5mA, ensuring safe operation without heatsinking in standard PCB layouts.
How does DG301ACJ+ compare to the original DG301CJ in terms of performance and compatibility?
DG301ACJ+ is the enhanced "A" version of DG301CJ, featuring improved absolute maximum ratings (V+ up to 44V vs. 36V), tighter leakage specs (<1nA vs. <5nA), and extended temperature range support. It remains pin-, function-, and logic-compatible with DG301CJ, allowing direct replacement in existing designs without layout or firmware changes.
