Product details
Overview
DG300ACWE+ from Maxim Integrated is a dual single-pole single-throw (SPST) CMOS analog switch with TTL/CMOS-compatible control inputs, <50Ω on-resistance, ±15V analog signal range, and break-before-make switching. It operates from ±5V to ±18V dual supplies or +10V to +30V single supply (V− = GND), targeting low-power portable instrumentation and sample/hold circuits.
For engineers reviewing the DG300ACWE+ datasheet, DG300ACWE+ pinout, DG300ACWE+ application, or DG300ACWE+ equivalent, key selection criteria include guaranteed 16-pin wide SOIC package, -25°C to +85°C operating temperature, <50Ω RDS(ON), sub-300ns switching times, and low 12pC charge injection-critical for precision analog signal routing in battery-powered systems.
Technical Context
The DG300ACWE+ implements monolithic CMOS switch architecture with latchup-proof construction and fully independent channel control logic. Its dual SPST topology supports discrete signal path enable/disable with no internal inter-channel coupling, and its substrate-isolated design ensures V+ to V− analog rail operation without signal clipping.
Break-before-make timing (50ns minimum) prevents transient shorting during state transitions, while low 14pF off-capacitance (CS(OFF)/CD(OFF)) and 40pF on-capacitance minimize signal distortion at high frequencies. Charge injection is tightly controlled at 12pC (typ) under ±15V supply, enabling accurate sampling in precision data acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail analog signals from V− to V+, eliminating level-shifting in bipolar sensor interfaces. |
| On-Resistance (RDS(ON)) | <50Ω (typ) - Ensures minimal voltage drop and gain error in precision amplifier and PGA signal paths. |
| Turn-On/Off Time | 150ns / 130ns (typ) - Enables fast multiplexing in multi-channel data loggers and real-time control loops. |
| Charge Injection | 12pC (typ) - Limits sampling error in 12-bit+ ADC front-ends and sample-and-hold applications. |
| Off-Leakage Current | <±0.1nA (typ) - Preserves signal integrity in high-impedance sensor nodes and ultra-low-power standby modes. |
| Supply Voltage Range | ±5V to ±18V dual or +10V to +30V single - Simplifies power architecture across industrial and portable designs. |
| Logic Compatibility | TTL and CMOS - Direct interface with microcontrollers, FPGAs, and legacy logic without level shifters. |
Pinout & Package
Package: 16-lead wide SOIC (SOIC-W), 7.6mm × 10.3mm body, 1.27mm 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-no functional role. |
| 8 | GND | Ground reference for digital control logic and substrate bias; critical for noise immunity and latchup prevention. |
| 16 | V+ | Positive supply rail; powers analog switch core and sets upper analog signal limit (V+ to V− range). |
| 14 | V− | Negative supply rail; defines lower analog signal limit and enables true bipolar operation. |
| 11, 12 | IN1, IN2 | Digital control inputs; active-high TTL/CMOS logic drives respective SPST switches ON/OFF independently. |
| 3, 4 | S1, S2 | Source terminals; connect to analog signal source (e.g., sensor output or DAC); current flows S→D when ON. |
| 1, 2 | D1, D2 | Drain terminals; connect to load (e.g., ADC input or amplifier stage); completes signal path when switch is closed. |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Switching | 50ns guaranteed interval prevents momentary short-circuit between channels during state transition. |
| Latchup-Proof Construction | Monolithic CMOS process with guard rings eliminates destructive latchup under overvoltage or ESD stress. |
| Single-Supply Capability | V− tied to GND enables +10V to +30V operation-reduces BOM count in battery-powered instruments. |
| Low On-Resistance Flatness | <50Ω across full analog range minimizes THD and gain error in audio and precision measurement paths. |
| Ultra-Low Charge Injection | 12pC typical ensures ≤0.5 LSB error in 12-bit SAR ADC sample/hold stages at 100kSPS. |

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, 4.5Ω RDS(ON), +1.8V to +36V single-supply only, 16-pin SOIC. | Better on-resistance but lacks dual-channel integration and ±V operation; requires level-shifting for TTL control. | Select MAX4617ESE+ only if ultra-low RDS(ON) and single-supply simplicity outweigh need for dual independent switches. |
| ADG1419BRUZ | Dual SPDT, 1.3Ω RDS(ON), ±15V supply, 16-pin TSSOP, higher cost, 1.5pC charge injection. | Superior performance in precision multiplexing but SPDT topology and TSSOP footprint differ from DG300ACWE+'s SPST/SOIC. | Choose ADG1419BRUZ when SPDT functionality and sub-2pC charge injection justify redesign and cost increase. |
Compared with MAX4617ESE+ and ADG1419BRUZ, the DG300ACWE+ delivers optimal balance of dual SPST integration, ±15V rail-to-rail analog handling, and proven reliability in portable instrumentation-without requiring PCB rework or logic-level adaptation.

FAQ
What is the maximum supply voltage rating for DG300ACWE+?
The DG300ACWE+ supports dual-supply operation up to ±18V (36V total), with absolute maximum V+ = 36V referenced to V−. For single-supply use, V− must be tied to GND and V+ can range from +10V to +30V. Exceeding these limits risks permanent damage per the Absolute Maximum Ratings table in the datasheet.
Does DG300ACWE+ support rail-to-rail analog signal switching?
Yes, the DG300ACWE+ supports analog signals spanning the full range from V− to V+, including ±15V operation. This rail-to-rail capability allows direct interfacing with bipolar sensors and op-amps without clamping or level-shifting, preserving signal integrity across the entire analog input range.
What is the guaranteed on-resistance specification for DG300ACWE+?
The DG300ACWE+ guarantees drain-source on-resistance (RDS(ON)) of ≤50Ω across the full analog signal range and operating temperature. Typical values are 30Ω at ±15V, with variation less than 10% between channels-critical for matched gain and low THD in precision signal paths.
How does DG300ACWE+ handle break-before-make timing?
The DG300ACWE+ implements a guaranteed 50ns break-before-make interval between switch transitions, preventing momentary short-circuits during state changes. This timing is inherent to the internal CMOS control logic and requires no external timing components-ensuring safe operation in multiplexed sensor arrays.
Is DG300ACWE+ compatible with standard TTL logic levels?
Yes, the DG300ACWE+ features fully TTL- and CMOS-compatible digital inputs (IN1, IN2). Logic high threshold is 2.0V min, and logic low is 0.8V max-allowing direct connection to 5V microcontrollers, FPGAs, and legacy logic families without level-shifting circuitry.
