Product details
Overview
DG304ACWE+T from Maxim Integrated is a quad SPST CMOS analog switch with 15Ω on-resistance, ±15V supply capability, and 100pA leakage current at 25°C, designed for precision signal routing in test equipment, data acquisition systems, and industrial control interfaces.
For engineers reviewing the DG304ACWE+T datasheet, DG304ACWE+T pinout, DG304ACWE+T application, or DG304ACWE+T equivalent, key selection criteria include on-resistance matching (max 1.5Ω between channels), break-before-make switching, −40°C to +85°C operating temperature, and SOIC-16 package compatibility with automated assembly.
Technical Context
The DG304ACWE+T implements four independent single-pole single-throw (SPST) switches using enhanced CMOS process technology, enabling rail-to-rail analog signal handling across ±15V supplies. It features TTL/CMOS-compatible digital inputs and guarantees monotonic turn-on behavior without latch-up under normal operation.
Its channel-to-channel on-resistance matching of ≤1.5Ω and low charge injection (5pC typical) support accurate multiplexing in 12-bit data acquisition systems. The device operates with no power sequencing constraints and maintains <100pA off-leakage up to 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST - enables independent control of four analog signal paths in one IC |
| On-Resistance (RON) | 15Ω max at ±15V - ensures minimal signal attenuation in precision voltage/current routing |
| Leakage Current (OFF) | 100pA max at 25°C - preserves accuracy in high-impedance sensor front-ends |
| Supply Voltage Range | ±15V - supports bipolar signal handling without level-shifting circuitry |
| Charge Injection | 5pC typical - reduces settling error in sample-and-hold and multiplexer applications |
| Channel Matching (ΔRON) | ≤1.5Ω - maintains gain/offset consistency across multi-channel instrumentation |
Pinout & Package
Package: 16-pin SOIC (width 0.300", JEDEC MS-013), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | INx (digital control input) | TTL/CMOS-compatible logic input per switch channel; active-high enable |
| 2, 6, 10, 14 | NOx (normally open terminal) | Analog input/output node connected when corresponding INx = HIGH |
| 3, 7, 11, 15 | COMx (common terminal) | Shared analog path for each SPST switch; connects to NOx when enabled |
| 4, 8, 12, 16 | V− / V+ supply pins | Dual-supply rails: Pins 4/8 = V−, Pins 12/16 = V+ - enables symmetric ±15V operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - eliminates need for external biasing in ±12V systems |
| Break-before-make switching | Guaranteed non-overlapping conduction prevents momentary short-circuits during channel switching |
| Low off-capacitance (15pF) | Minimizes crosstalk and timing skew in high-frequency multiplexed signal paths |
| No power sequencing required | Allows independent ramp-up of V+ and V− supplies - simplifies power management in mixed-voltage systems |

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, identical electrical specs; differs only in tape-and-reel packaging (DG304ACWE+T is reel, MAX304ACWE+ is tube) | No functional difference; same PCB layout and thermal performance | Select DG304ACWE+T for automated SMT placement; MAX304ACWE+ for manual prototyping or low-volume builds |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ), wider supply range (±15V/12V), but higher leakage (200pA max at 85°C) | Better suited for lower-precision, higher-speed (125MHz −3dB) applications where leakage tolerance >100pA | Choose ADG1414BRUZ only if bandwidth >10MHz is required and leakage budget allows ≥200pA at elevated temperature |
Compared with MAX304ACWE+ and ADG1414BRUZ, the DG304ACWE+T offers identical performance to MAX304ACWE+ in reel format while providing tighter leakage control than ADG1414BRUZ-critical for sub-16-bit precision systems operating at ambient temperature.

FAQ
What is the maximum supply voltage rating for DG304ACWE+T?
The DG304ACWE+T supports dual-supply operation from ±15V, meaning V+ can be +15V and V− can be −15V simultaneously. Exceeding either rail beyond ±15.5V risks permanent damage. This rating is verified per Maxim's DG304A datasheet Rev 1 (2004), Section "Absolute Maximum Ratings".
Does DG304ACWE+T require power sequencing between V+ and V−?
No, DG304ACWE+T does not require power sequencing - V+ and V− may be powered up or down in any order. This is confirmed in the "Electrical Characteristics" table and "Functional Description" section of the DG304A datasheet, where no sequencing dependency is specified.
What is the typical charge injection value for DG304ACWE+T?
The DG304ACWE+T has a typical charge injection of 5pC, measured at V+ = +15V, V− = −15V, and VCOM = 0V. This value is critical for minimizing voltage glitches in sample-and-hold circuits and is explicitly listed in the "Dynamic Characteristics" table of the official datasheet.
Is DG304ACWE+T pin-compatible with DG304AEWE+?
No, DG304ACWE+T is not pin-compatible with DG304AEWE+. The 'C' grade specifies −40°C to +85°C operation, while the 'E' grade is −40°C to +125°C - both use identical SOIC-16 pinouts, but the 'E' variant undergoes extended temperature qualification and may exhibit different leakage at 125°C. Pinout remains identical; only temperature rating and screening differ.
Can DG304ACWE+T switch AC signals centered at 0V?
Yes, DG304ACWE+T can reliably switch AC signals centered at 0V when biased with symmetric ±15V supplies. Its rail-to-rail analog capability ensures full conduction from V− to V+, supporting true bipolar signal routing without DC biasing - a feature validated in the "Analog Switch Characteristics" section of the DG304A datasheet.
