Product details
Overview
DG307AAK-E3 from Vishay Siliconix is a monolithic CMOS dual SPST analog switch with 14-pin CERDIP package, –55 °C to +125 °C operating range, 30 Ω typical rDS(on), 110 ns tON, and full rail-to-rail signal handling (±15 V). It serves as a precision signal routing element in programmable gain amplifiers and battery-powered instrumentation.
For engineers reviewing the DG307AAK-E3 datasheet, DG307AAK-E3 pinout, DG307AAK-E3 application, or DG307AAK-E3 equivalent, this page delivers verified pin mapping, real-world switching performance metrics, temperature-rated operation limits, and functionally matched alternatives for high-reliability analog signal path design.
Technical Context
The DG307AAK-E3 implements two independent single-pole single-throw (SPST) switches fabricated on Vishay's PLUS-40 CMOS process, enabling micropower operation (30 nW) without compromising speed. Each switch supports bidirectional conduction, break-before-make timing (50 ns), and latchup immunity via epitaxial isolation.
It operates from dual ±15 V supplies (V+ = +15 V, V– = –15 V), accepts CMOS-compatible logic inputs (VINH = 11 V, VINL = 3.5 V), and maintains flat on-resistance across the full analog range (–15 V to +15 V), making it suitable for precision low-distortion signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - Supports full rail-to-rail input/output swing with no clipping at supply rails. |
| rDS(on) (Typ) | 30 Ω - Low on-resistance ensures minimal signal attenuation and voltage drop in analog paths. |
| tON/tOFF | 110 ns / 70 ns - Enables fast multiplexing in data acquisition and real-time control loops. |
| Supply Range | ±15 V - Dual-supply operation allows symmetric bipolar signal handling for precision instrumentation. |
| Leakage Current (Max) | ±100 nA - Ultra-low off-state leakage preserves signal integrity in high-impedance sensor interfaces. |
| Charge Injection | 30 pC - Minimizes transient glitches during switching in sample-and-hold and ADC front-end circuits. |
| Off-Isolation | 62 dB - Provides strong channel-to-channel rejection for multi-channel signal routing applications. |
Pinout & Package
Package: 14-pin ceramic dual-in-line package (CERDIP), hermetically sealed, rated for –55 °C to +125 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 6, 9, 12, 13 | No Connect (NC) | Internally unconnected; must remain floating or tied to GND per layout best practice. |
| 2 | V+ | Positive supply rail (+15 V max); also substrate/case connection in metal-can variants (not applicable here). |
| 3, 4 | D1, D2 | Drain terminals of SPST switches; bidirectional analog signal outputs/inputs. |
| 7, 14 | S1, S2 | Source terminals of SPST switches; bidirectional analog signal outputs/inputs. |
| 10, 11 | IN1, IN2 | CMOS-compatible digital control inputs; active-high (11 V threshold) enables direct microcontroller interface. |
| 8 | GND | Analog ground reference; separate from digital ground in mixed-signal systems to minimize noise coupling. |
| 13 | V– | Negative supply rail (–15 V max); required for bipolar signal support and rail-to-rail operation. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (±15 V not supported); 1.8 Ω rDS(on); 16-pin TSSOP package. | Requires level-shifting for bipolar signal handling; better suited for low-voltage, high-precision DC-coupled systems. | Select ADG1419BRUZ when ultra-low on-resistance and space-constrained PCB layout outweigh dual-supply flexibility. |
| MAX4677ESE+ | –40 °C to +85 °C rating; 45 Ω rDS(on); 16-pin SOIC; no guaranteed break-before-make. | Not qualified for extended temperature industrial/military use; higher on-resistance increases gain error in precision gain stages. | Choose MAX4677ESE+ only for cost-sensitive commercial-grade applications where full temperature range and timing guarantees are non-critical. |
Compared with DG307AAK-E3, ADG1419BRUZ offers lower rDS(on) but lacks dual-supply capability and extended temperature support, while MAX4677ESE+ trades performance and reliability for lower cost and wider commercial availability-neither is pin-compatible, and both require PCB redesign.

FAQ
What is the maximum analog signal voltage range supported by the DG307AAK-E3?
The DG307AAK-E3 supports a full rail-to-rail analog signal range of ±15 V when operated with V+ = +15 V and V– = –15 V. This is guaranteed by design and enables undistorted passage of bipolar signals up to the supply rails without clipping or compression, critical for precision instrumentation and process control interfaces.
Does the DG307AAK-E3 require external pull-up or pull-down resistors on its digital inputs?
No, the DG307AAK-E3 does not require external pull-up or pull-down resistors. Its CMOS-compatible digital inputs (IN1 and IN2) have negligible input current (±1 pA typical), and logic thresholds are internally defined at 3.5 V (low) and 11 V (high). Direct connection to microcontroller GPIOs or FPGA outputs is fully supported without additional biasing components.
Can the DG307AAK-E3 be used with a single +15 V supply instead of dual ±15 V?
Yes, the DG307AAK-E3 supports single-supply operation: tie V– to 0 V (GND) and apply V+ = +15 V. In this configuration, the analog signal range becomes 0 V to +15 V, preserving rail-to-rail functionality for unipolar signals. However, bipolar operation and full ±15 V range require both V+ and V– supplies as specified.
What is the thermal derating behavior of the DG307AAK-E3 in its 14-pin CERDIP package?
The DG307AAK-E3 in 14-pin CERDIP has a power dissipation limit of 825 mW at +25 °C, derated linearly at 6.5 mW/°C above +25 °C. At its maximum operating temperature of +125 °C, usable power dissipation drops to approximately 170 mW. This derating ensures safe junction temperature under continuous load in high-temperature industrial environments.
How does the DG307AAK-E3 ensure signal integrity during switching transitions?
The DG307AAK-E3 ensures signal integrity through three key mechanisms: guaranteed break-before-make timing (50 ns minimum), low charge injection (30 pC), and flat rDS(on) (<5 % variation across –15 V to +15 V). These features collectively minimize transients, DC offset steps, and gain nonlinearity-essential for sample-and-hold circuits, programmable gain amplifiers, and precision multiplexers using DG307AAK-E3.
