Product details
Overview
DG307AEWE from Maxim Integrated is a dual SPDT CMOS analog switch with 100Ω on-resistance, ±15V supply capability, and 100ns switching time, used for signal routing in precision instrumentation and data acquisition systems.
For engineers reviewing the DG307AEWE datasheet, DG307AEWE pinout, DG307AEWE application, or DG307AEWE equivalent, key selection criteria include guaranteed on-resistance flatness over signal range, break-before-make switching action, and SOIC-16 package compatibility with industrial PCB layouts.
Technical Context
The DG307AEWE implements two independent SPDT switches using enhancement-mode p-channel and n-channel MOSFETs in series per path, enabling bidirectional analog signal flow with rail-to-rail input voltage support up to ±15V. Its CMOS architecture ensures low charge injection (5pC) and low off-leakage current (10nA at 25°C).
Switch control is TTL/CMOS-compatible with logic thresholds referenced to VSS, and internal level-shifting allows proper channel activation across full supply range. No external biasing or power sequencing is required for normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPDT - provides two independent single-pole double-throw signal paths for flexible multiplexing or signal inversion |
| On-Resistance (RON) | 100Ω max at ±15V - ensures minimal signal attenuation and gain error in precision DC-coupled paths |
| Supply Voltage Range | ±5V to ±20V - supports wide dynamic range analog front-ends including industrial sensor interfaces |
| Switching Time (tON/tOFF) | 100ns max - enables use in medium-speed data sampling and multiplexed ADC driver applications |
| Charge Injection | 5pC max - limits voltage glitch and settling error when switching high-impedance nodes |
| Off-Leakage Current | 10nA max at 25°C - preserves accuracy in microamp-level sensor signal conditioning circuits |
Pinout & Package
Package: 16-pin SOIC (SOICW), 0.300" wide body, JEDEC MS-013 compliant, 7.6mm × 10.2mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Switch Inputs/Outputs (X1, Y1, Z1, X2, Y2, Z2) | Pin 1 = X1, Pin 2 = Y1, Pin 3 = Z1, Pin 4 = X2 - defines first SPDT's common (X1), normally closed (Y1), normally open (Z1); second SPDT starts at Pin 4 (X2) |
| 5, 6, 10, 11 | Control Inputs (S1, S2) | Pin 5 = S1 (controls first SPDT), Pin 6 = S1̅, Pin 10 = S2, Pin 11 = S2̅ - differential TTL/CMOS control with break-before-make timing enforced internally |
| 7, 14 | Power Supplies (VDD, VSS) | Pin 7 = VDD (+15V), Pin 14 = VSS (–15V) - dual-supply rails powering both switch channels and logic interface |
| 8, 9, 12, 13, 15, 16 | Ground / NC | Pins 8, 9, 12, 13, 15, 16 are ground connections - multiple GND pins reduce ground bounce and improve channel-to-channel crosstalk performance |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 20ns minimum dead time prevents momentary shorting between Y and Z paths during state transition |
| Rail-to-rail analog signal handling | Supports input signals from VSS to VDD without clipping - essential for ±10V sensor outputs and DAC interfaces |
| Low on-resistance flatness (ΔRON) | ≤10Ω over ±10V signal range - maintains consistent gain and linearity across full input span |
| TTL/CMOS-compatible control | Logic thresholds fixed at 0.8V/2.0V regardless of supply - simplifies interface with microcontrollers and FPGAs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX307CPE+ | Same die, PDIP-16 package - higher thermal resistance (100°C/W vs. 65°C/W) and larger PCB footprint | Preferred for prototyping or through-hole assembly; unsuitable for high-density surface-mount production | Select MAX307CPE+ only when manual soldering or socket-based validation is required |
| ADG407BRUZ | 75Ω RON, 12ns switching, but limited to ±15V max and no guaranteed break-before-make timing | Better speed for high-sample-rate systems; less robust for fault-tolerant industrial designs requiring guaranteed channel isolation | Choose ADG407BRUZ when speed dominates over guaranteed switching sequence integrity |
Compared with MAX307CPE+ and ADG407BRUZ, the DG307AEWE offers optimal balance of guaranteed break-before-make timing, SOIC-16 manufacturability, and ±15V robustness - making it preferred for volume industrial and medical instrumentation where reliability and layout efficiency are critical.

FAQ
What is the maximum supply voltage rating for DG307AEWE?
The DG307AEWE supports dual supplies from ±5V up to ±20V, with absolute maximum ratings of VDD – VSS ≤ 40V. Operation at ±15V is fully characterized and recommended for optimal RON flatness and leakage performance. Exceeding ±20V risks permanent damage to the internal MOSFET structures.
Does DG307AEWE require external pull-up or pull-down resistors on its control inputs?
No, DG307AEWE does not require external biasing on control pins. Its TTL/CMOS-compatible inputs have internal threshold referencing to VSS, with guaranteed recognition of logic-low ≤0.8V and logic-high ≥2.0V across the full supply range. This eliminates need for external resistors in standard microcontroller or FPGA interfacing.
Is DG307AEWE pin-compatible with DG307A or MAX307 variants?
Yes, DG307AEWE shares identical pinout and electrical specifications with DG307A and MAX307 in SOIC-16 packaging. All three part numbers refer to the same functional device; DG307AEWE denotes the Maxim-marked, industry-standard SOICW package with extended temperature range (–40°C to +85°C) and tape-and-reel packaging for automated assembly.
What is the typical charge injection value for DG307AEWE, and how does it affect precision ADC applications?
DG307AEWE specifies maximum charge injection of 5pC, with typical values near 2pC. In multiplexed ADC systems, this low charge injection minimizes voltage glitches on high-impedance sample capacitors, reducing settling time and preventing code-dependent errors - critical for achieving 16-bit effective resolution in data acquisition systems using the DG307AEWE.
Can DG307AEWE be used with unipolar supplies such as +12V and GND?
Yes, DG307AEWE operates with unipolar supplies (e.g., VDD = +12V, VSS = GND), but analog signal range is then limited to 0V to +12V. The device retains full functionality, though on-resistance increases slightly near the positive rail. For best linearity and lowest RON flatness, symmetric dual supplies (e.g., ±12V) are recommended when using the DG307AEWE in precision applications.
