Product details
Overview
DG304ACWE+ from Maxim Integrated is a single-pole double-throw (SPDT) CMOS analog switch with 100 Ω on-resistance, ±15 V analog signal range, and 10 nA leakage current at 25°C. It operates from a dual ±5 V to ±20 V supply and is used in precision instrumentation multiplexing and audio signal routing.
For engineers reviewing the DG304ACWE+ datasheet, DG304ACWE+ pinout, DG304ACWE+ application, or DG304ACWE+ equivalent, key selection criteria include guaranteed on-resistance flatness over signal range, break-before-make switching action, and SOIC-W16 package compatibility with high-density PCB layouts.
Technical Context
The DG304ACWE+ implements a complementary MOSFET structure with matched P- and N-channel devices per switch path, enabling symmetrical conduction and low charge injection (0.5 pC typical). Its control logic accepts TTL/CMOS-compatible input levels referenced to VSS.
Designed for bidirectional analog signal handling, it supports rail-to-rail operation with no minimum signal swing requirement and maintains <±0.5 mV offset error across its full ±15 V analog range when used with matched external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPDT - enables selection between two analog paths using one control input |
| On-Resistance (RON) | 100 Ω max at ±15 V supply - ensures minimal signal attenuation in precision gain-setting networks |
| Analog Signal Range | ±15 V - supports full-range operation with standard op-amp supplies without level-shifting |
| Leakage Current (IOFF) | 10 nA max at 25°C - preserves accuracy in high-impedance sensor front-ends |
| Charge Injection | 0.5 pC typical - reduces settling error in sample-and-hold circuits |
| Supply Voltage Range | ±5 V to ±20 V - allows flexible biasing in mixed-signal systems with varying rail requirements |
Pinout & Package
Package: 16-pin wide-body SOIC (SOIC-W), 7.6 mm × 10.3 mm body, 1.27 mm pitch, JEDEC MS-013 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Channel Inputs/Outputs | Four independent SPDT switch channels; pins 1–2 = CH1, 3–4 = CH2, etc. |
| 9, 10, 11, 12 | Control Inputs | Active-high digital inputs selecting common-to-NO or common-to-NC path per channel |
| 13, 14 | Power Supplies | VDD (+) and VSS (–) - dual supplies required for full ±15 V analog swing |
| 15, 16 | Common Terminals | Two independent COM terminals - each serves two SPDT switches in shared-common configuration |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 20 ns minimum break time prevents momentary shorting during channel transitions |
| Low on-resistance flatness | ±5 Ω variation over ±10 V signal range - maintains linearity in programmable-gain amplifiers |
| TTL/CMOS-compatible control | Logic thresholds fixed at 0.8 V / 2.4 V - eliminates need for level translators with microcontroller GPIOs |
| Rail-to-rail analog capability | Operates with signals extending to both supply rails - enables direct interfacing with ADCs/DACs without clamping diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX304ACWE+ | Same die, rebranded by Maxim; identical electrical specs and pinout | No functional difference - used interchangeably in legacy designs | Select DG304ACWE+ for continuity with Dallas Semiconductor legacy sourcing |
| ADG1414BRUZ | Lower RON (1.8 Ω), higher supply current (2 mA), requires single 5 V or dual ±15 V | Better for low-voltage, low-RON apps; not suitable where ultra-low leakage (<100 pA) is critical | Choose ADG1414BRUZ only if on-resistance reduction outweighs increased power and leakage trade-offs |
Compared with MAX304ACWE+, DG304ACWE+ offers identical performance and footprint but reflects original Dallas branding; versus ADG1414BRUZ, DG304ACWE+ provides superior leakage control and lower supply current at the cost of higher RON, making it preferable in high-impedance, low-power precision systems.

FAQ
What is the maximum supply voltage rating for DG304ACWE+?
The DG304ACWE+ supports dual supplies from ±5 V to ±20 V. Its absolute maximum rating is ±22 V on VDD and VSS. Exceeding ±20 V may degrade RON stability and increase leakage beyond datasheet limits. Always refer to the DG304ACWE+ Absolute Maximum Ratings table for derating guidance at elevated temperatures.
Does DG304ACWE+ support single-supply operation?
No, DG304ACWE+ requires dual symmetric supplies (e.g., ±15 V) to achieve its specified ±15 V analog signal range and guaranteed on-resistance flatness. Single-supply operation is not characterized or supported - attempting it results in undefined switching behavior and potential signal clipping near the negative rail.
What is the typical charge injection value for DG304ACWE+?
The DG304ACWE+ exhibits 0.5 pC typical charge injection per switch transition, measured at VDD = +15 V, VSS = –15 V, and TA = 25°C. This low value minimizes voltage glitches in sample-and-hold circuits and improves settling performance in precision acquisition systems using the DG304ACWE+.
Is DG304ACWE+ pin-compatible with DG305ACWE+?
No, DG304ACWE+ and DG305ACWE+ are not pin-compatible. DG304ACWE+ is a quad SPDT switch in 16-pin SOIC-W, while DG305ACWE+ is a dual SPDT in 14-pin SOIC-N. Their pin counts, layouts, and internal channel configurations differ - direct replacement would require PCB redesign and firmware logic updates for the DG304ACWE+.
What package type does DG304ACWE+ use?
DG304ACWE+ uses a 16-pin wide-body SOIC (SOIC-W) package per JEDEC MS-013, with 7.6 mm × 10.3 mm body dimensions and 1.27 mm lead pitch. This package provides improved thermal dissipation and creepage distance compared to narrow SOIC, supporting reliable operation in industrial environments where the DG304ACWE+ is commonly deployed.
