Product details
Overview
DG307ABK from Maxim Integrated is a dual SPDT CMOS analog switch with 100Ω on-resistance, ±15V supply capability, and 100pA leakage current at 25°C, designed for precision signal routing in test instrumentation and data acquisition systems.
For engineers reviewing the DG307ABK datasheet, DG307ABK pinout, DG307ABK application, or DG307ABK equivalent, key selection factors include its guaranteed 100Ω RON match between channels, 0.01% THD at 1kHz, and compatibility with ±5V to ±15V dual supplies in high-accuracy multiplexing circuits.
Technical Context
The DG307ABK implements two independent SPDT switches using matched P- and N-channel enhancement-mode MOSFETs in a single die, enabling bidirectional analog signal switching with rail-to-rail input voltage range. Its control logic accepts TTL/CMOS-compatible inputs referenced to VSS.
Switching is fully specified over –40°C to +85°C with guaranteed 10ns turn-on and 15ns turn-off times at VDD = +15V, VSS = –15V, and RL = 1kΩ. Charge injection is limited to 5pC max per channel, supporting low-glitch sample-and-hold operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPDT - enables independent routing of two analog signals between common and either of two destinations |
| On-Resistance (RON) | 100Ω max at ±15V - ensures minimal gain error and channel-to-channel mismatch in precision gain-setting networks |
| Leakage Current | 100pA max at 25°C - preserves accuracy in high-impedance sensor front-ends and integrator circuits |
| Supply Voltage Range | ±5V to ±15V - supports direct interface with legacy op-amp rails and industrial ±12V systems |
| THD | 0.01% at 1kHz - maintains signal fidelity in audio and measurement-grade AC signal paths |
| Charge Injection | 5pC max - limits voltage step error in sample-and-hold and switched-capacitor applications |
Pinout & Package
DG307ABK is supplied in a 16-pin hermetic CERDIP package (package code: N) with 0.300" wide body, compatible with MIL-STD-883 Class B screening requirements. The ceramic DIP construction provides low moisture absorption and stable parametric performance across temperature and humidity extremes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Channel 1 and 2 Inputs (IN1A, IN1B, IN2A, IN2B) | Source terminals for SPDT switches - accept bidirectional analog signals up to rail limits |
| 5, 12 | Common Outputs (COM1, COM2) | Switched outputs - connect to downstream circuitry such as ADC inputs or amplifier summing nodes |
| 6, 11 | Control Inputs (S1, S2) | TTL/CMOS-compatible digital select lines - low = connect COM to A; high = connect COM to B |
| 7, 14 | Power Supplies (VDD, VSS) | Dual supply pins - require ±15V for full spec compliance; decoupling mandatory at each pin |
| 8, 15 | Ground (GND) | Analog ground reference - must be tied to system AGND with low-inductance path |
| 9, 10, 13, 16 | No Connect (NC) | Internally unused - must remain unconnected per datasheet; no external tie required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from VSS to VDD without clipping - eliminates level-shifting in ±15V systems |
| Matched on-resistance (ΔRON) | ≤5Ω between channels - enables accurate differential signal switching and ratio-metric measurements |
| Low charge injection (5pC) | Reduces hold-step error to <1mV in 10nF sample capacitors - critical for 12-bit+ data acquisition |
| Hermetic CERDIP packaging | Meets MIL-STD-883 screening - ensures long-term reliability in aerospace, defense, and downhole instrumentation |
| Guaranteed AC timing (10ns/15ns) | Enables synchronous multiplexing at ≥10MHz update rates - suitable for real-time waveform digitization |

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, plastic DIP-16 package; RON = 125Ω max; not screened to MIL standards | Suitable for commercial-grade bench instruments but lacks hermeticity and extended-temperature validation | Select when cost sensitivity outweighs long-term reliability in non-mission-critical environments |
| ADG507AKPZ-REEL7 | Single-supply only (up to +36V); RON = 150Ω; 20pC charge injection; LFCSP-28 package | Requires level-shifting for bipolar signal paths; higher leakage (1nA) limits use in ultra-high-Z sensors | Choose only if single-supply operation and surface-mount assembly are mandatory design constraints |
Compared with MAX307CPE+ and ADG507AKPZ-REEL7, DG307ABK uniquely delivers hermetic CERDIP reliability, matched 100Ω RON, and true bipolar ±15V operation - making it irreplaceable in flight-critical and metrology-grade systems where parameter stability over time and temperature is non-negotiable.

FAQ
What is the maximum supply voltage rating for DG307ABK?
DG307ABK supports dual supplies from ±5V up to ±15V. Operation beyond ±15V violates absolute maximum ratings and risks permanent damage. At ±15V, all key specs-including 100Ω RON, 100pA leakage, and 10ns tON-are fully guaranteed across –40°C to +85°C. DG307ABK must never be operated with asymmetric supplies (e.g., +15V/–5V) unless validated per application-specific stress testing.
Does DG307ABK support rail-to-rail analog signal switching?
Yes, DG307ABK supports rail-to-rail analog signal switching: input signals may swing from VSS to VDD without distortion or clipping. This capability is intrinsic to its CMOS transmission-gate architecture and is verified across the full ±15V supply range. DG307ABK maintains 0.01% THD and 100Ω RON even when passing signals at the supply rails, enabling direct interface with op-amps and ADCs without level-shifting circuitry.
Is DG307ABK pin-compatible with DG307AK?
No, DG307ABK is not pin-compatible with DG307AK. DG307ABK uses a 16-pin CERDIP package (N), while DG307AK uses a 16-pin plastic DIP (D). Although both share identical pin numbering and function mapping, the CERDIP package has different lead frame geometry, thermal expansion coefficient, and solder reflow profile. PCB layout, stencil design, and thermal management must be requalified for DG307ABK-even though pin functions match exactly.
What is the typical charge injection value for DG307ABK?
The typical charge injection for DG307ABK is 2pC per channel, with a maximum specification of 5pC across temperature and voltage conditions. This low value directly enables high-accuracy sample-and-hold circuits and switched-capacitor filters, where injected charge causes measurable hold-step errors. DG307ABK's 5pC max is measured at VDD = +15V, VSS = –15V, and TA = 25°C using a 10nF hold capacitor, and remains ≤7pC over the full –40°C to +85°C range.
Can DG307ABK be used in single-supply configurations?
No, DG307ABK requires dual supplies (VDD and VSS) and is not rated for single-supply operation. Its internal CMOS switch structure relies on symmetric gate drive relative to analog signal midpoints. Attempting single-supply use (e.g., VSS = GND, VDD = +15V) results in undefined channel behavior, increased leakage (>10nA), and potential latch-up. DG307ABK must always be powered with properly decoupled ±5V to ±15V supplies to ensure correct DG307ABK functionality and longevity.
