AD1674TD/883B

The AD1674TD/883B is a complete 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices and qualified to MIL-STD-883 Class B standards. Housed in a ceramic dual-inline package (CDIP), the device integrates an on-chip sample-and-hold amplifier, precision voltage reference, and clock oscillator, enabling fully autonomous conversion with minimal external circuitry. It delivers a throughput of 100 kSPS with a typical conversion time of 10 µs and accepts both unipolar and bipolar analog input ranges selected via pin-strap configuration. Pin-compatible with the industry-standard AD574 and AD674 families, this converter offers an upgrade path with improved speed and reduced power dissipation while retaining a parallel microprocessor interface and internal scaling for straightforward system integration.

This ADC addresses high-reliability data acquisition in defense avionics, aerospace instrumentation, industrial process control, and other mission-critical systems that must operate across extended temperature extremes. The /883B suffix denotes conformance to MIL-STD-883 screening, including full temperature range testing from −55 °C to +125 °C, burn-in, and hermetic ceramic packaging suitable for severe shock, vibration, and humidity environments. For procurement engineering, the AD1674TD/883B represents a legacy military-grade component with long production support for sustained defense and aerospace programs. Lead times may reflect controlled Class B flow, and qualification documentation is typically available to satisfy mandated traceability and configuration control requirements.
