Product details
Overview
DG300ABWE+ from Maxim Integrated is a dual single-pole single-throw (SPST) CMOS analog switch with TTL/CMOS-compatible control inputs, <50Ω on-resistance, ±5V to ±18V dual-supply operation, and break-before-make switching. It supports analog signal ranges from V− to V+, delivers 150ns turn-on time, and is optimized for low-power portable instrumentation and battery-powered sample/hold circuits.
For engineers reviewing the DG300ABWE+ datasheet, DG300ABWE+ pinout, DG300ABWE+ application, or DG300ABWE+ equivalent, this page provides verified technical context, package mapping, real-world design values, and validated alternative options for SPST analog switching in industrial and portable systems requiring stable rail-to-rail signal handling and minimal charge injection.
Technical Context
The DG300ABWE+ implements monolithic CMOS switch architecture with latchup-proof construction and fully independent channel control logic. Its dual SPST topology enables discrete signal path selection without internal crosstalk coupling, and its substrate-connected V+ terminal ensures robust ESD immunity and stable analog performance across temperature.
Break-before-make timing is explicitly specified only for DG301(A)/DG303(A) variants per datasheet test circuits - not applicable to DG300ABWE+. The device operates with true rail-to-rail analog voltage range (V− to V+), supports single-supply use via V− = GND, and maintains <50Ω RDS(ON) at ±15V supplies with 0.5%/°C temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (V− to V+) - supports full-rail signal switching without clipping in ±15V systems |
| On-Resistance (RDS(ON)) | <50Ω typ - ensures minimal signal attenuation and gain error in precision signal paths |
| Turn-On Time (tON) | 150ns typ - enables fast multiplexing in data acquisition and sampling applications |
| Charge Injection | 12pC max - limits voltage glitch in sample/hold and ADC front-end circuits |
| Off-Leakage Current | <±0.1nA typ - preserves accuracy in high-impedance sensor interfaces and integrators |
| Supply Range | ±5V to ±18V dual supply, or +10V to +30V single supply (V− = GND) - flexible power architecture support |
| Logic Compatibility | TTL and CMOS input thresholds (0.8V/4.0V) - interoperable with legacy and modern digital controllers |
Pinout & Package
Package: 16-lead wide SOIC (SOIC-W), 7.6mm × 10.3mm body, 1.27mm lead pitch, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15 | No Connect (N.C.) | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 8 | GND | Ground reference for logic and substrate; required for single-supply operation |
| 16 | V+ | Positive supply and substrate connection; ties die substrate to highest potential for latchup immunity |
Key Features
| Feature | Design Value |
|---|---|
| Latchup-proof CMOS process | Prevents destructive latchup under overvoltage or ESD stress, critical for field-reliable instrumentation |
| Rail-to-rail analog range | Switches signals from V− to V+ without distortion - eliminates need for level-shifting in ±15V systems |
| Low charge injection (12pC) | Minimizes hold-step error in precision sample/hold amplifiers and switched-capacitor circuits |
| Break-before-make excluded | DG300ABWE+ has independent SPST channels - no inter-channel timing dependency; avoids signal shorting risks |
| Single-supply capability | V− = GND enables +10V to +30V operation - simplifies power design in portable and industrial DC systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | 44V max supply, 0.6Ω RDS(ON), 16-lead TSSOP, requires external VDD/VSS decoupling | Better on-resistance and bandwidth, but higher cost and stricter layout requirements for high-speed stability | Select when ultra-low RDS(ON) and 10MHz bandwidth are required; not drop-in due to different pinout and supply sequencing needs |
| TS5A23157DCKR | +5V single-supply only, 0.9Ω RDS(ON), 6-pin SC70, 300mA continuous current | Optimized for low-voltage consumer portables; lacks dual-supply and rail-to-rail analog range | Choose for space-constrained +3.3V/+5V systems where ±15V operation is unnecessary; incompatible for bipolar signal routing |
Compared with ADG1419BRUZ and TS5A23157DCKR, the DG300ABWE+ uniquely supports ±18V dual supplies and rail-to-rail analog switching in a wide SOIC package - making it irreplaceable for industrial and test equipment requiring robust bipolar signal handling without redesigning power or layout.

FAQ
What is the operating temperature range for DG300ABWE+?
The DG300ABWE+ is rated for −25°C to +85°C ambient operation, as confirmed by Maxim's ordering information table. This B-grade temperature range supports industrial and extended-environment applications where commercial-grade (0°C to +70°C) devices would fail. The device maintains specified RDS(ON), leakage, and switching times across this full range per electrical characteristics tables.
Does DG300ABWE+ support single-supply operation?
Yes, DG300ABWE+ supports single-supply operation by connecting V− to GND. It functions across +10V to +30V supply voltages in this configuration, with analog signal range extending from GND to V+. Table 1 in the datasheet confirms tON = 70ns and RDS(ON) = 31Ω at +30V, validating robust performance in high-voltage DC systems.
Is DG300ABWE+ pin-compatible with the original DG300 series?
Yes, DG300ABWE+ is pin-compatible with other DG300A-series variants in the same 16-lead wide SOIC package (e.g., DG300ACWE, DG300BWE). Maxim explicitly states "DG300–DG303 and DG300A–DG303A families are electrically compatible and pin compatible with the original manufacturer's devices," confirming mechanical and functional interchangeability within the A-suffix SOIC footprint.
What is the maximum analog signal voltage DG300ABWE+ can switch?
DG300ABWE+ switches analog signals from V− to V+, with absolute maximum ratings of V+ ≤ +44V and V− ≥ −44V for DG300A variants. At ±15V supplies, the analog range is ±15V; at +30V single supply (V− = GND), the range is 0V to +30V. Exceeding V+ or V− clamps signals via internal diodes - forward current must be limited to 30mA per datasheet Note 1.
How does DG300ABWE+ handle charge injection in sample/hold applications?
DG300ABWE+ specifies 12pC typical charge injection (Q) with ±15V supplies and 0V input, measured into a 10nF load. This results in ≤1.2mV hold-step error in a 10-bit 5V system - well within tolerance for most precision data acquisition. The value is confirmed in Figure 1 test circuit and Table 2, and remains stable across input voltage swings from −10V to +10V.
