Product details
Overview
DG202AK/883B from Maxim Integrated is a quad SPST analog switch with normally open configuration, designed for high-reliability analog signal routing in military and aerospace systems. It operates over ±4.5V to ±18V dual supplies, delivers 115Ω typical RDS(ON) at ±15V, guarantees break-before-make switching, and supports -55°C to +125°C operation in hermetic CERDIP packaging.
For engineers reviewing the DG202AK/883B datasheet, DG202AK/883B pinout, DG202AK/883B application, or DG202AK/883B equivalent, key selection criteria include guaranteed analog signal range (±15V), low leakage (±100nA max over full temperature), latch-up immunity during supply disconnect, CMOS/TTL logic compatibility, and absence of VL supply requirement.
Technical Context
The DG202AK/883B implements four independent, inverted-control SPST switches using monolithic CMOS process technology. Each switch features symmetrical conduction (bidirectional current flow), constant on-resistance across the full analog signal range, and no output signal offset - enabling precision signal path integrity in multiplexing and gain-setting circuits.
It eliminates the third logic supply (VL) required by legacy equivalents while maintaining pin- and function-compatibility with DG201/DG211 family. Its nonlatching behavior under live-signal/no-supply conditions ensures robust fault tolerance in mission-critical power-down scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail analog signals without clipping or distortion when powered at ±15V. |
| RDS(ON) | 115Ω (typ), 250Ω (max) - Enables low insertion loss and minimal voltage drop in precision analog paths. |
| Off-Leakage Current | ±100nA (max) - Ensures minimal signal corruption in high-impedance sample/hold and sensor interfaces. |
| Turn-On/Off Time | 480ns / 370ns (typ) - Supports fast-switching applications such as automatic test equipment and communications channel selection. |
| Supply Range | ±4.5V to ±18V - Allows flexible system-level power architecture design without external level-shifting. |
| Operating Temp | -55°C to +125°C - Qualified for extended-temperature military and avionics deployments per MIL-PRF-38535 Class K. |
| OFF-Isolation | 70dB - Provides strong channel-to-channel signal rejection in multiplexer configurations. |
Pinout & Package
Package: 16-pin CERDIP (Ceramic Dual In-line Package), hermetically sealed, MIL-STD-883 qualified, lead finish SnPb.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs - Low = switch ON; compatible with TTL/CMOS logic thresholds. |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - Analog signal outputs; bidirectional, no polarity restriction. |
| 3, 6, 11, 14 | S1–S4 | Source terminals - Analog signal inputs; symmetric with drains for true bidirectional routing. |
| 4 | V− | Negative supply rail - Must be connected to system negative supply; substrate reference. |
| 5 | GND | Digital ground - Logic reference point; separate from analog signal return paths. |
| 12 | N.C. | No connection - Internally unconnected; must remain floating or grounded per layout best practice. |
| 13 | V+ | Positive supply rail - Connected to substrate; requires stable ±15V or ±18V supply. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates dedicated logic supply rail - simplifies power architecture and reduces BOM count vs. legacy DG212. |
| Guaranteed break-before-make | Prevents momentary shorting between channels during state transitions - critical for safe analog multiplexing. |
| Nonlatching under live-signal/no-supply | Remains electrically stable even if input signals persist after V+/V− removal - essential for fault-tolerant systems. |
| Constant RDS(ON) over signal range | Minimizes harmonic distortion and gain error in programmable gain amplifiers and precision instrumentation. |
| Bidirectional analog conduction | Enables flexible signal routing without polarity constraints - supports both source-to-drain and drain-to-source paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG202AKRZ-REEL | Requires VL supply; ±15V operation; 120Ω RDS(ON); -40°C to +85°C rating | Lacks extended temperature and MIL-spec qualification; not suitable for space or high-reliability avionics | Select only for commercial-grade systems where VL supply is available and temperature range is limited. |

FAQ
What is the maximum analog signal voltage range supported by DG202AK/883B?
The DG202AK/883B supports an analog signal range of ±15V when operated at ±15V supplies. This is specified in the Electrical Characteristics table for the DG202A grade and confirmed across the full -55°C to +125°C operating temperature range. Signals exceeding this range may forward-bias internal protection diodes, so clamping or external protection is recommended for overvoltage conditions.
Does DG202AK/883B require a VL logic supply voltage?
No, DG202AK/883B does not require a VL supply. Unlike earlier DG212 variants, Maxim eliminated the need for a third logic supply while preserving compatibility with existing DG201/DG211 control interfaces. All logic inputs operate directly from standard CMOS/TTL levels referenced to GND, with no external VL rail needed.
What is the leakage current specification for DG202AK/883B over its full temperature range?
The DG202AK/883B specifies ±100nA maximum off-leakage current (both IS(OFF) and ID(OFF)) across the full -55°C to +125°C operating range. This value is explicitly listed in the "ELECTRICAL CHARACTERISTICS (DG202)" table for the DG202A grade and applies to all four channels under worst-case bias conditions (e.g., VS = ±14V, VD = ∓14V).
Is DG202AK/883B pin-compatible with DG201 or DG211 devices?
Yes, DG202AK/883B is pin-compatible with DG201 and DG211 devices in the same 16-pin CERDIP package. The pin functions match exactly, though DG202AK/883B uses inverted logic control (low = ON), whereas DG201/DG211 use non-inverted control. System-level logic inversion must be accounted for during replacement.
What packaging and qualification standards apply to DG202AK/883B?
DG202AK/883B is supplied in a 16-pin hermetic CERDIP package and is qualified per MIL-PRF-38535 Class K, including screening for burn-in, temperature cycling, and hermeticity. It meets the requirements for high-reliability military and aerospace applications, with full traceability and lot-specific test data available upon request.
