Product details
Overview
DG301ACWE+ from Maxim Integrated is a dual SPDT CMOS analog switch IC designed for precision signal routing in low-power, bipolar-supply systems. It features <50Ω on-resistance, 150ns turn-on time, ±15V analog signal range (V+ to V−), break-before-make switching, and TTL/CMOS-compatible control inputs - enabling reliable operation in portable instrumentation and sample/hold circuits.
For engineers reviewing the DG301ACWE+ datasheet, DG301ACWE+ pinout, DG301ACWE+ application, or DG301ACWE+ equivalent, this device is selected for battery-powered analog multiplexing where low charge injection (12pC), minimal on-resistance variation, and rail-to-rail signal handling are critical design requirements.
Technical Context
The DG301ACWE+ implements two independent SPDT switches using monolithic CMOS process technology with latchup-proof construction. Each switch supports bidirectional analog signal flow from V− to V+, operates across ±5V to ±18V dual supplies (or +10V to +30V single supply with V− = GND), and guarantees break-before-make timing of 50ns between channels.
Its control logic accepts standard TTL/CMOS voltage levels (0.8V/4.0V thresholds), exhibits <1nA off-leakage at ±14V, and delivers matched on-resistance (<10% channel-to-channel variation) with 0.5%/°C temperature coefficient - ensuring stable gain and offset in programmable amplifier and telemetry front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (V− to V+): enables rail-to-rail AC/DC signal switching without clipping in ±15V systems. |
| On-Resistance (RDS(ON)) | <50Ω typ at ±15V: minimizes insertion loss and gain error in precision signal paths. |
| Turn-On Time (tON) | 150ns max: supports sampling rates up to ~3MHz in data acquisition systems. |
| Charge Injection | 12pC typ: reduces settling error in sample-and-hold and switched-capacitor circuits. |
| Off-Leakage Current | <1nA at ±14V: preserves accuracy in high-impedance sensor interfaces and integrators. |
| Supply Range | ±5V to ±18V dual or +10V to +30V single: simplifies power architecture in mixed-signal PCBs. |
| Logic Compatibility | TTL/CMOS input thresholds (0.8V/4.0V): allows direct interfacing with microcontrollers and FPGAs. |
Pinout & Package
Package: 16-lead wide SOIC (SOIC-W), body width 7.5mm, JEDEC MS-013 compliant, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | No Connect (N.C.) | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| 3 (S1), 5 (D1), 6 (D2), 8 (S2) | Analog Switch Terminals | S1/D1 and S2/D2 form two independent SPDT paths; bidirectional signal routing with V− to V+ range. |
| 4 (IN1), 7 (IN2) | Digital Control Inputs | Active-high TTL/CMOS logic: IN1 controls S1↔D1, IN2 controls S2↔D2. |
| 9 (GND) | Ground Reference | Logic and substrate reference; separate from analog signal ground in mixed-signal layouts. |
| 10 (V−) | Negative Supply Rail | Required for bipolar operation; tied to GND for single-supply mode (+10V to +30V). |
| 14 (V+) | Positive Supply Rail | Supports up to +18V; substrate/case connection defines analog signal ceiling. |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Switching | 50ns guaranteed interval prevents momentary shorting in SPDT signal path reconfiguration. |
| Latchup-Proof CMOS Process | Immune to destructive latchup under overvoltage or ESD stress in industrial environments. |
| Low Charge Injection (12pC) | Minimizes voltage step error in sample/hold amplifiers and precision ADC front-ends. |
| Rail-to-Rail Analog Range | V− to V+ conduction enables full utilization of ±15V op-amp rails without level-shifting. |
| Single-Supply Capability | V− = GND support simplifies power design in portable instruments using +12V or +15V rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 35Ω RDS(ON), 16-pin SO, ±20V supply rating. | Lower channel count; no break-before-make; optimized for high-speed digital signal routing. | Select when only one switch path is needed and faster tON (75ns) is prioritized over SPDT topology. |
| ADG1419BRUZ | Dual SPDT, 1.3Ω RDS(ON), 16-pin TSSOP, ±15V rating, but higher 1.5mA supply current. | Ultra-low on-resistance ideal for audio/precision DAC buffering, not optimized for ultra-low power. | Select when sub-2Ω on-resistance is mandatory and battery life is secondary to signal fidelity. |
Compared with MAX4617ESE+ and ADG1419BRUZ, the DG301ACWE+ uniquely balances low power (0.5mA), SPDT functionality, break-before-make timing, and cost-effective SOIC-W packaging - making it optimal for portable test equipment and multi-channel telemetry where power, reliability, and topology align.

FAQ
What is the operating temperature range for DG301ACWE+?
The DG301ACWE+ is rated for 0°C to +70°C ambient operation, as indicated by the 'C' suffix in its ordering code. This commercial-grade temperature range suits indoor portable instruments and benchtop test equipment where environmental extremes are controlled. The device maintains specified on-resistance, leakage, and switching performance across this full range, with derating applied only above +75°C for package power dissipation.
Can DG301ACWE+ operate from a single +12V supply?
Yes, DG301ACWE+ supports single-supply operation: connect V− to GND and apply +12V to V+. The analog signal range becomes 0V to +12V, and logic inputs remain compatible with standard 0.8V/4.0V thresholds. Performance metrics including RDS(ON) (≈42Ω), tON (110ns), and charge injection (8pC at +5V input) are confirmed in Table 1 of the datasheet for +12V conditions.
Does DG301ACWE+ support break-before-make switching on both SPDT channels?
Yes, DG301ACWE+ guarantees break-before-make operation for both SPDT channels, with a minimum 50ns interval between turn-off of one path and turn-on of the alternate path. This is explicitly tested and specified in the Break-Before-Make Interval parameter (tON − tOFF) for DG301(A)/DG303(A) devices, preventing signal shorting during state transitions in critical analog routing applications.
What is the maximum analog signal voltage DG301ACWE+ can switch?
DG301ACWE+ supports analog signals from V− to V+, with absolute maximum ratings of ±18V on V+ and V−. At ±15V supplies, the full ±15V range is usable - verified by VANALOG = −15V to +15V in Electrical Characteristics. Exceeding V+ or V− clamps signals via internal diodes; forward current must be limited to 30mA per terminal to avoid damage.
Is DG301ACWE+ pin-compatible with legacy DG301 devices?
Yes, DG301ACWE+ is electrically and pin-compatible with original DG301-series devices, including DG301CWE and DG301BWE, as confirmed in the General Description: "DG300–DG303 and DG300A–DG303A families are electrically compatible and pin compatible with the original manufacturer's devices." Pin count, function mapping, and SOIC-W footprint match exactly, enabling drop-in replacement in existing designs.
