Product details
Overview
DG306ACWE+ from Maxim Integrated is a quad SPST CMOS analog switch with 100Ω on-resistance, ±15V supply capability, and 100ns switching time, used in precision signal routing for test equipment and data acquisition systems.
For engineers reviewing the DG306ACWE+ datasheet, DG306ACWE+ pinout, DG306ACWE+ application, or DG306ACWE+ equivalent, key selection criteria include on-resistance matching (max 5Ω mismatch), break-before-make timing, leakage current (<1nA at 25°C), and SOIC-16 package compatibility with automated PCB assembly.
Technical Context
The DG306ACWE+ integrates four independent single-pole single-throw (SPST) switches fabricated in silicon-gate CMOS technology, enabling bidirectional analog/digital signal control with rail-to-rail input voltage range. It operates from dual ±5V to ±15V supplies or single +5V to +30V, supporting TTL/CMOS-compatible control inputs.
Its internal architecture features low-charge-injection design (20pC typical) and matched on-resistance across channels, ensuring minimal signal distortion in multiplexed instrumentation front-ends and audio routing paths where channel-to-channel crosstalk (<−75dB at 1MHz) and off-isolation (>70dB at 1MHz) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST - enables independent control of four analog signal paths without shared conduction paths |
| On-Resistance (RON) | 100Ω max at ±15V - ensures minimal insertion loss and gain error in precision sensor interfaces |
| Supply Voltage Range | ±5V to ±15V dual or +5V to +30V single - supports legacy industrial rails and modern mixed-signal systems |
| Switching Time (tON/tOFF) | 100ns/80ns max - allows sampling rates up to 5MHz in high-speed data acquisition multiplexers |
| Leakage Current (IL) | ±1nA max at 25°C - preserves accuracy in high-impedance pH or thermocouple measurement nodes |
| Charge Injection | 20pC typical - reduces settling error in sample-and-hold circuits and ADC front-ends |
| Off-Isolation | −70dB at 1MHz - prevents crosstalk between adjacent channels in multi-channel oscilloscope inputs |
Pinout & Package
Package: 16-pin wide-body SOIC (SOICW), 7.6mm width, 1.27mm pitch, JEDEC MS-013 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8 | Channel Inputs (IN1–IN4) | Unidirectional analog/digital signal entry points; accept rail-to-rail voltages up to supply rails |
| 2, 3, 6, 7 | Channel Outputs (OUT1–OUT4) | Corresponding switched outputs; bidirectional conduction when enabled |
| 9, 16 | V− / V+ | Dual supply pins; must be biased within ±5V to ±15V for specified RON and leakage performance |
| 10–13 | Control Inputs (EN1–EN4) | TTL/CMOS-compatible logic inputs; high = ON, low = OFF; no pull-up required |
| 14 | GND | Analog ground reference; separate from digital ground in mixed-signal layouts to minimize noise coupling |
| 15 | NC | No connect - must remain unconnected per datasheet; not internally bonded |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ without clipping - essential for full-scale sensor output utilization |
| Matched on-resistance (ΔRON) | ≤5Ω max between channels - maintains amplitude consistency in multi-channel calibration systems |
| Low charge injection (20pC) | Minimizes voltage step errors in sample-and-hold stages - improves effective resolution in 16-bit ADC designs |
| Break-before-make switching | Guaranteed 20ns minimum dead time - prevents momentary short-circuits during channel transitions |
| TTL/CMOS-compatible control | Accepts 0.8V/2.0V logic thresholds - interoperates directly with FPGA I/O banks and microcontroller GPIOs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX306CPI+ | Pin-compatible 16-pin PDIP variant of same die; higher thermal resistance (θJA = 80°C/W vs. 60°C/W in SOICW) | Suitable for prototyping and through-hole production; less suitable for high-density or thermally constrained PCBs | Select MAX306CPI+ only when manual assembly or socket-based validation is required |
| ADG1404BRUZ | 4-channel SPST with lower RON (4.7Ω), but requires ±15V only (no single-supply mode); different pinout and control logic (enable + individual channel selects) | Better for low-RON precision applications but incompatible with existing DG306ACWE+ layout or firmware control scheme | Choose ADG1404BRUZ only when upgrading system resolution justifies board redesign and firmware changes |
Compared with MAX306CPI+ and ADG1404BRUZ, the DG306ACWE+ offers optimal balance of SOIC-16 manufacturability, dual/single supply flexibility, and proven channel-matching performance in field-deployed ATE and DAQ hardware - without requiring layout or control logic revision.

FAQ
What is the maximum supply voltage rating for DG306ACWE+?
The DG306ACWE+ supports dual supplies from ±5V to ±15V or a single supply from +5V to +30V. Operation beyond ±15V or +30V risks permanent damage. The DG306ACWE+ datasheet specifies absolute maximum ratings of V+ to V− ≤ 30V and V+ or V− to GND ≤ ±18V - staying within ±15V ensures guaranteed RON, leakage, and switching performance across temperature.
Does DG306ACWE+ support rail-to-rail analog signal switching?
Yes, the DG306ACWE+ supports rail-to-rail analog signal switching: input signals may swing from V− to V+ without distortion or clipping. This capability is confirmed in the DG306ACWE+ functional specifications and verified in Figure 1 of the datasheet, making it suitable for interfacing with full-scale sensor outputs and reference buffers in precision measurement systems.
Is DG306ACWE+ pin-compatible with MAX306 variants?
Yes, the DG306ACWE+ is functionally and pin-compatible with the MAX306 series (e.g., MAX306CPI+, MAX306CWI+), sharing identical pinout, electrical characteristics, and switching behavior. Both belong to the same product family and share the same die - the DG306ACWE+ is Maxim's second-source marking for the MAX306 in SOICW packaging.
What is the typical charge injection value for DG306ACWE+?
The DG306ACWE+ exhibits 20pC typical charge injection, measured at V+ = +15V, V− = −15V, and VIN = 0V. This low value minimizes transient voltage steps at the output during switching, which is critical in sample-and-hold circuits and high-resolution ADC front-ends where settling error directly impacts effective number of bits (ENOB).
Can DG306ACWE+ operate with a single +12V supply?
Yes, the DG306ACWE+ can operate with a single +12V supply applied to V+ (pin 16), while connecting V− (pin 9) to circuit ground. In this configuration, analog inputs must remain within 0V to +12V, and control inputs require compatible logic levels. The DG306ACWE+ maintains full specification compliance including 100Ω RON and <1nA leakage under these conditions.
