AD587TQ/883B

The AD587TQ/883B is a precision 10 V monolithic voltage reference manufactured by Analog Devices, a recognized leader in high-reliability analog integrated circuits. Housed in a hermetic ceramic dual-inline package (CDIP), the device integrates a buried Zener diode reference core with a precision output amplifier, laser-trimmed to deliver a stable 10.000 V output. The design emphasizes very low temperature drift, excellent long-term stability, and low output noise, providing a consistent reference that maintains tight initial accuracy and low output impedance under varying load and environmental conditions.

Typical deployments include precision analog-to-digital and digital-to-analog converter references, industrial calibration standards, process control instrumentation, and high-accuracy laboratory measurement systems. The “/883B” suffix denotes full compliance with MIL-STD-883 Class B screening, qualifying the part for mission-critical defense and aerospace applications such as avionics, radar signal processing, navigation, and satellite payloads, where operation over the full military temperature range and proven reliability are mandatory. Procurement specialists should take into account that this screened, ceramic-packaged variant may be subject to longer lead times, export licensing requirements, and mil-spec traceability documentation. As a hermetic device inherently resistant to moisture and mechanical stress, it supports long-term field reliability, though verifying ongoing production status and lifecycle support directly with the manufacturer remains an important step for long-duration programs.
