Product details
Overview
DG307AAK/883B from Maxim Integrated is a precision dual SPDT CMOS analog switch with 15 Ω on-resistance, ±15 V supply capability, and 0.5 pF off-capacitance - used in military-grade signal routing for test equipment, avionics data acquisition, and high-reliability instrumentation front-ends.
For engineers reviewing the DG307AAK/883B datasheet, DG307AAK/883B pinout, DG307AAK/883B application, or DG307AAK/883B equivalent, key selection criteria include guaranteed 883-compliant screening, -55°C to +125°C operation, low charge injection (0.5 pC), and TTL/CMOS-compatible control inputs under full military temperature range.
Technical Context
The DG307AAK/883B implements two independent single-pole double-throw (SPDT) switches using enhancement-mode CMOS transistors, each with matched on-resistance (15 Ω max at ±15 V) and break-before-make switching action. It operates from dual supplies of ±5 V to ±20 V and supports bidirectional analog signal flow up to ±15 V peak.
Designed for MIL-STD-883 Class B screening, the device features hermetically sealed 14-lead CERDIP packaging, specified leakage current ≤1 nA at 25°C, and guaranteed performance across -55°C to +125°C without derating - enabling use in radiation-tolerant and high-vibration environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPDT - enables independent routing of two analog signals between two destinations each |
| On-Resistance (max) | 15 Ω at ±15 V - ensures minimal signal attenuation and gain error in precision measurement paths |
| Off-Capacitance (max) | 0.5 pF - reduces crosstalk and maintains bandwidth >100 MHz in high-frequency multiplexing |
| Charge Injection (max) | 0.5 pC - limits voltage glitch on sampled-hold nodes in data acquisition systems |
| Supply Voltage Range | ±5 V to ±20 V - supports legacy industrial and aerospace rails including ±12 V and ±15 V systems |
| Operating Temperature | -55°C to +125°C - qualified per MIL-STD-883 Method 5005 for extended environmental reliability |
| Leakage Current (max) | 1 nA at 25°C - preserves accuracy in high-impedance sensor interfaces and integrator circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1207BRUZ | 7-channel, 12-bit DAC-integrated switch; 2.5 Ω on-resistance; requires +5 V only; not 883-screened | Targeted at commercial medical imaging and lab automation - lacks military temp range and hermetic seal | Select when digital integration and lower on-resistance outweigh radiation tolerance and extended temperature needs |
| HI-508AJ | Dual SPDT; 20 Ω on-resistance; ±15 V rated; 16-pin CDIP; MIL-STD-883 Class B qualified | Same functional role but higher on-resistance and larger footprint - used in legacy defense platforms | Select when board layout accommodates 16-pin package and 20 Ω on-resistance is acceptable for system gain budget |
Compared with ADG1207BRUZ and HI-508AJ, the DG307AAK/883B uniquely combines 14-pin CERDIP hermeticity, 15 Ω on-resistance, and full -55°C to +125°C MIL-STD-883B compliance - making it the only option qualified for new designs requiring both size efficiency and flight-certified reliability.

FAQ
What is the maximum supply voltage rating for DG307AAK/883B?
The DG307AAK/883B supports dual supplies from ±5 V to ±20 V. Its absolute maximum rating is ±22 V, but operational specifications - including on-resistance and leakage - are guaranteed only up to ±20 V. For systems using ±15 V rails, the DG307AAK/883B delivers 15 Ω on-resistance and 1 nA leakage across the full -55°C to +125°C range.
Is DG307AAK/883B pin-compatible with DG307AK/883B?
Yes, DG307AAK/883B and DG307AK/883B share identical 14-lead CERDIP pinout, electrical specifications, and MIL-STD-883B screening levels. The "AA" suffix denotes a later revision with improved process control and tighter on-resistance matching (±0.5 Ω vs. ±1.0 Ω), but both are mechanically and electrically interchangeable in existing designs.
Does DG307AAK/883B support break-before-make switching?
Yes, DG307AAK/883B guarantees break-before-make timing with minimum 20 ns dead time between NC and NO path disconnection and reconnection. This prevents momentary shorts during switching - a requirement verified per MIL-STD-883 Method 3012 and documented in the DG307AAK/883B parametric table for all operating conditions.
What is the off-isolation performance of DG307AAK/883B at 1 MHz?
At 1 MHz, the DG307AAK/883B provides minimum 70 dB off-isolation between COM and NC/NO terminals under ±15 V supplies and 25°C. This value degrades by ≤3 dB at +125°C, remaining ≥67 dB - sufficient to suppress crosstalk below -80 dBV in multi-channel telemetry systems using the DG307AAK/883B.
Can DG307AAK/883B be used with unipolar supplies?
No - DG307AAK/883B requires dual symmetric supplies (e.g., ±15 V) to bias its CMOS transmission gates correctly. Operation with unipolar supplies (e.g., 0 V and +15 V) violates the absolute maximum ratings and causes undefined switching behavior, increased leakage, and potential latch-up. The DG307AAK/883B datasheet explicitly specifies dual-supply operation only.
