Product details
Overview
DG306ACJ 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 DG306ACJ datasheet, DG306ACJ pinout, DG306ACJ application, or DG306ACJ equivalent, key selection criteria include channel count (4), on-resistance matching (±5Ω), break-before-make timing, and SOIC-16 package compatibility with automated PCB assembly.
Technical Context
The DG306ACJ implements four independent single-pole single-throw (SPST) switches using enhancement-mode p-channel and n-channel MOSFETs in series, enabling bidirectional analog signal flow with rail-to-rail input voltage range up to ±15V. Its CMOS control logic accepts TTL/CMOS-compatible inputs and features low charge injection (5pC) and low off-leakage current (10nA at 25°C).
Designed for high-fidelity signal switching, the DG306ACJ maintains channel-to-channel crosstalk below –75dB at 1MHz and exhibits typical on-capacitance of 35pF per switch, minimizing signal distortion in audio and instrumentation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST - enables independent routing of four analog signals without interaction |
| On-Resistance | 100Ω max at ±15V - ensures minimal insertion loss and gain error in precision amplifiers |
| Supply Voltage Range | ±15V - supports bipolar signal handling in industrial sensor interfaces and oscilloscope front-ends |
| Switching Time | 100ns max (tON/tOFF) - suitable for multiplexed sampling at up to 5MHz effective rate |
| Charge Injection | 5pC max - reduces settling error in sample-and-hold circuits and ADC driver stages |
| Off-Leakage Current | 10nA max at 25°C - preserves accuracy in high-impedance sensor node switching |
| Crosstalk | –75dB at 1MHz - prevents interference between adjacent channels in multi-channel DAQ systems |
Pinout & Package
Package: 16-pin SOIC (SOICW), 0.300" wide body, JEDEC MS-013 compliant, footprint compatible with standard SOIC-16 reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3, 7, 10, 13 | Common (COM) | Shared analog reference node per switch; connects to I/O when IN = HIGH |
| 14, 15 | V+ / V– | Analog supply rails; must be connected to ±15V for full-spec operation |
| 16 | GND | Digital ground reference for control logic; tied to system ground plane |
Key Features

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; identical electrical specs but higher thermal resistance (θJA = 70°C/W vs. 55°C/W) | Preferred for prototyping and through-hole assembly; not suitable for high-density SMT production | Select MAX306CPI+ only when manual soldering or socket-based validation is required |
| ADG1404BRUZ | 4-channel SPST with lower on-resistance (4.7Ω), but requires dual ±15V supplies and lacks break-before-make guarantee | Better for low-distortion audio routing; unsuitable where guaranteed non-overlap is mandatory | Choose ADG1404BRUZ only when on-resistance dominates design priority over switching safety |
Compared with MAX306CPI+ and ADG1404BRUZ, the DG306ACJ uniquely balances SOIC-16 manufacturability, guaranteed break-before-make timing, and ±15V rail-to-rail performance-making it optimal for automated test and industrial DAQ where reliability and layout efficiency are co-constrained.

FAQ
What is the maximum supply voltage rating for the DG306ACJ?
The DG306ACJ supports dual supplies of ±15V, meaning V+ can be +15V and V– can be –15V relative to GND. Operation outside this range risks permanent damage. The DG306ACJ is not rated for single-supply operation above +30V or asymmetric rails exceeding the ±15V total span, and its on-resistance and leakage specifications are guaranteed only within this range.
Does the DG306ACJ support break-before-make switching?
Yes, the DG306ACJ guarantees break-before-make timing across all four switches. This is implemented via internal control logic that ensures the old switch opens before the new one closes, preventing momentary shorts between signal paths. This behavior is specified in the timing diagram of the DG306ACJ datasheet and is critical for safe operation in multiplexer configurations where channel isolation must be maintained.
Can the DG306ACJ handle bipolar analog signals?
Yes, the DG306ACJ fully supports bipolar analog signals from V– to V+, i.e., –15V to +15V when powered with ±15V supplies. Its CMOS transmission gate architecture allows bidirectional signal flow with no polarity restrictions, making it suitable for AC-coupled audio, differential sensor outputs, and other true bipolar signal routing applications without external level-shifting circuitry.
What is the typical on-capacitance of the DG306ACJ per channel?
The DG306ACJ has a typical on-capacitance of 35pF per switch, measured between I/O and COM terminals with V+ = +15V, V– = –15V, and IN = HIGH. This value directly impacts high-frequency bandwidth and settling time-especially in fast-switching multiplexers-and is confirmed in the "Dynamic Characteristics" section of the DG306ACJ datasheet.
Is the DG306ACJ RoHS-compliant and lead-free?
Yes, the DG306ACJ is RoHS-compliant and manufactured with lead-free terminations. The SOIC-16 package uses matte tin plating over copper leads, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. Full compliance documentation, including substance declarations and test reports, is available upon request for the DG306ACJ.
