Vishay Siliconix DG200AAA/883

Overview

DG200AAA/883 from Vishay Siliconix is a monolithic dual SPST CMOS analog switch in a 10-pin metal can package, rated for –55 °C to +125 °C operation, with ±15 V analog signal range, 45 Ω typical on-resistance, and TTL/CMOS-compatible digital inputs - used in precision servo control switching and programmable gain amplifiers.

For engineers reviewing the DG200AAA/883 datasheet, DG200AAA/883 pinout, DG200AAA/883 application, or DG200AAA/883 equivalent, key selection considerations include its MIL-STD-883 qualified 10-pin metal can construction, bidirectional analog conduction, latchup-immune PLUS-40 CMOS process, and guaranteed 44 V maximum supply range across V+ to V–.

Technical Context

The DG200AAA/883 integrates two independent single-pole, single-throw switches fabricated using Vishay's PLUS-40 CMOS process with epitaxial isolation to prevent latchup. Each channel conducts equally in both directions when ON and blocks up to 30 V peak-to-peak when OFF, with no intrinsic offset voltage introduced in the ON state.

It operates from split supplies (V+, V–) with logic thresholds referenced to GND, supports analog signals from V– to V+, and clamps input overvoltage via internal diodes - requiring external current limiting per terminal to ≤30 mA continuous or ≤100 mA pulsed (1 ms, 10% duty).

FAQ

What is the operating temperature range for DG200AAA/883?

The DG200AAA/883 is specified for operation from –55 °C to +125 °C, fully qualified per MIL-STD-883 Class B screening including temperature cycling and steady-state life testing. This range is validated across all electrical parameters in the datasheet, including on-resistance, leakage, and switching times - making DG200AAA/883 suitable for extreme-environment applications such as satellite payload electronics and jet engine control units.

Does DG200AAA/883 require external current limiting on digital inputs?

Yes, DG200AAA/883 requires external current limiting on IN1 and IN2 if driven beyond the supply rails (V+ or V–), because internal clamping diodes conduct when VIN exceeds (V+) + 0.7 V or falls below (V–) – 0.7 V. Per the datasheet, forward diode current must be limited to ≤30 mA continuous - typically achieved using series resistors sized per worst-case logic driver voltage and rail margins. This applies to DG200AAA/883 regardless of whether TTL or CMOS logic families are used.

Can DG200AAA/883 be used with unipolar supplies?

No - DG200AAA/883 requires dual-polarity supplies (V+, V–, and GND) to operate correctly. Its analog signal range extends from V– to V+, and its digital inputs are referenced to GND. Using only a positive supply (e.g., V+ = +15 V, V– = GND) violates the absolute maximum rating for GND-to-V– (25 V), risks latchup, and invalidates all guaranteed specifications. The DG200AAA/883 must be powered as specified: V+ > GND > V–, with V+ – V– ≤ 44 V.

What is the purpose of the V+ Substrate pin (Pin 6) on DG200AAA/883?

The V+ Substrate pin (Pin 6) on DG200AAA/883 serves two critical functions: it electrically connects the metal can case to the positive supply rail (V+), providing a low-inductance return path for substrate currents, and acts as the primary thermal conduction path from the die to the mounting surface. This pin must be soldered directly to a V+-referenced copper plane or heatsink - floating or grounding it violates the device's internal biasing and may cause functional failure or parametric shift in DG200AAA/883 performance.

How does DG200AAA/883 handle analog signals exceeding the supply rails?

DG200AAA/883 does not support analog signals exceeding the V– to V+ range - such signals forward-bias internal junctions and cause uncontrolled conduction or damage. The absolute maximum analog voltage is strictly bounded by V– and V+, with no overvoltage tolerance. Unlike some newer analog switches, DG200AAA/883 lacks rail-to-rail input protection beyond its internal clamp diodes, which only protect digital inputs. Therefore, external clamping or level-shifting circuitry is mandatory if the system must handle signals beyond the DG200AAA/883 supply rails.
