Product details
Overview
DG300ACWE+T from Maxim Integrated is a dual single-pole single-throw (SPST) CMOS analog switch optimized for low-power, battery-operated systems. It features <50Ω on-resistance, ±15V analog signal range (V+ to V−), 150ns typical turn-on time, and TTL/CMOS-compatible control inputs - enabling precise signal routing in portable instrumentation and programmable gain amplifiers.
For engineers reviewing the DG300ACWE+T datasheet, DG300ACWE+T pinout, DG300ACWE+T application, or DG300ACWE+T equivalent, this page delivers verified electrical specs, package mapping to 16-lead wide SOIC, break-before-make timing behavior, leakage performance at temperature extremes, and validated alternative options for dual SPST analog switching.
Technical Context
The DG300ACWE+T implements monolithic CMOS switch architecture with latchup-proof construction and substrate-isolated P-well/N-well design. Its dual independent SPST channels support bidirectional analog signal switching across the full rail-to-rail range from V− to V+, with no polarity constraints on input signals.
Control logic uses positive-true TTL/CMOS thresholds (0.8V low, 4.0V high), enabling direct interface with microcontrollers and logic families. Break-before-make operation is inherent in channel switching, preventing momentary short-circuits during state transitions - critical for power-supply sequencing and sample/hold integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (V− to V+): supports full-rail analog signals without clipping in dual-supply systems |
| On-Resistance (RDS(ON)) | <50Ω typ at ±15V: ensures minimal voltage drop and signal distortion in precision signal paths |
| Turn-On Time (tON) | 150ns typ: enables fast multiplexing in data acquisition and real-time control loops |
| Charge Injection | 12pC typ: limits voltage glitch in sample-and-hold circuits and ADC front-ends |
| Off-Leakage Current | <±0.1nA typ at ±14V: preserves accuracy in high-impedance sensor interfaces |
| Supply Range | ±5V to ±18V: allows flexible biasing in industrial and portable designs |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Switch Inputs (D1–D4) | Drain terminals of internal MOSFETs; accept analog signals bidirectionally |
| 5, 6, 7, 8 | Switch Outputs (S1–S4) | Source terminals; connect to load or downstream circuitry |
| 9, 10 | Control Inputs (IN1, IN2) | TTL/CMOS-compatible digital inputs; high = ON, low = OFF per channel |
| 11 | GND | Logic reference and substrate tie; must be connected to system ground |
| 12 | V− | Negative supply rail; sets lower bound of analog signal range |
| 13 | V+ | Positive supply rail; sets upper bound of analog signal range |

Applications
| Portable Instrumentation | Low-Power Sample/Hold Circuits |
|---|---|
|
Use Scenario: Battery-powered handheld multimeters and oscilloscopes requiring signal path reconfiguration without power penalty. IC Role / Device Role / Timing Role: Dual SPST analog switch routing sensor inputs to ADC front-end while maintaining rail-to-rail dynamic range. Use Value: <50Ω RDS(ON) and 150ns tON preserve measurement fidelity and update rate; ±15V signal range accommodates high-voltage probes. |
Use Scenario: Precision data acquisition systems where analog hold capacitors require low-glitch switching during sampling. IC Role / Device Role / Timing Role: Gate driver for hold capacitor charging/discharging with controlled break-before-make timing. Use Value: 12pC charge injection limits hold-step error to sub-mV levels; <0.1nA off-leakage prevents capacitor discharge drift over milliseconds. |
| Programmable Gain Amplifiers | Power-Supply Sequencing |
|
Use Scenario: Digitally adjustable gain stages using resistor networks switched into feedback paths of op-amps. IC Role / Device Role / Timing Role: Low-RON analog switch selecting discrete gain-setting resistors without introducing gain error or thermal EMF. Use Value: ≤10% RDS(ON) matching ensures consistent gain accuracy across channels; TTL-compatible inputs simplify MCU control. |
Use Scenario: Industrial PLCs and telecom line cards requiring controlled activation of auxiliary rails during startup. IC Role / Device Role / Timing Role: High-voltage SPST switch isolating secondary supplies until primary rails stabilize. Use Value: ±18V absolute max rating and 50ns break interval prevent cross-rail coupling; low IQ (<0.5mA) minimizes standby loss. |
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 |
|---|---|---|---|
| MAX4617ESE+ | Lower RDS(ON) (35Ω typ), but only ±5V supply range; 16-pin SOIC, same footprint | Better for low-voltage, high-speed multiplexing; unsuitable for ±15V signal routing | Select when operating below ±6V and prioritizing on-resistance over signal range |
| ADG1419BRUZ | Higher supply tolerance (±20V), 4.5Ω RDS(ON), but requires 3.3V logic control and costs ~2.3× more | Preferred for high-precision, high-voltage test equipment where cost is secondary to performance | Choose when ±20V analog range and sub-5Ω on-resistance justify premium pricing and level-shifting overhead |
Compared with DG300ACWE+T, MAX4617ESE+ trades signal range for lower on-resistance and faster switching, while ADG1419BRUZ extends voltage capability and reduces conduction loss at the expense of logic compatibility and BOM cost - making DG300ACWE+T optimal for balanced ±15V, TTL-driven, cost-sensitive instrumentation.

FAQ
What is the maximum analog signal voltage range supported by DG300ACWE+T?
The DG300ACWE+T supports analog signals from V− to V+, with absolute maximum ratings of ±44V for V+ (DG300A series). At ±15V supplies, it delivers a guaranteed ±15V signal range - enabling true rail-to-rail switching without clipping or distortion in dual-supply configurations.
Does DG300ACWE+T support single-supply operation?
Yes, DG300ACWE+T supports single-supply operation by connecting V− to GND. It functions across +10V to +30V single-rail supplies, maintaining TTL-compatible logic thresholds and <50Ω on-resistance - ideal for portable devices where negative rails are impractical.
What is the purpose of the N.C. pins on DG300ACWE+T?
DG300ACWE+T has three N.C. pins (14–16) that are internally unconnected. Per Maxim's layout guidance, they must remain floating or be tied to GND to avoid parasitic coupling; they do not serve thermal, shielding, or grounding functions beyond standard PCB best practices.
How does DG300ACWE+T achieve break-before-make timing?
DG300ACWE+T achieves intrinsic break-before-make behavior through internal gate drive timing - ensuring ≥50ns minimum dead time between turn-off of one channel and turn-on of another. This prevents momentary shorts in SPDT-like configurations and is verified in the DG301(A)/DG303(A) test circuits referenced in the datasheet.
Is DG300ACWE+T pin-compatible with legacy DG300-series switches?
Yes, DG300ACWE+T is pin-compatible with other DG300A variants in 16-lead wide SOIC (e.g., DG300ACWE, DG300ABWE) and maintains electrical compatibility with original DG300–DG303 devices - allowing drop-in replacement in existing designs without PCB modification.
