Overview
The MAT02BH/883C is a matched dual monolithic NPN transistor manufactured by Analog Devices Inc. under the Precision Monolithics brand, designed for low noise and low drift applications. It utilizes a Silicon Nitride Triple Passivation process to stabilize critical device parameters across wide temperature ranges. Key electrical characteristics include a maximum offset voltage of 50 µV, a minimum current gain (hFE) of 500 at IC=1 mA, and an excellent log conformance with rBE approximately equal to 0.3Ω. The component operates within a specified temperature range and is housed in a hermetic package suitable for high-reliability environments.
Feature Summary
- Matched dual monolithic NPN transistors optimized for very low noise and low drift performance.
- Silicon Nitride Triple Passivation process ensures parameter stability over wide temperature and time ranges.
- High current gain maintained across a broad collector current spectrum.
- Excellent logarithmic conformance with minimal base resistance.
Applications
- Precision instrumentation amplifier input stages requiring low offset and noise.
- Low-noise analog signal processing circuits.
- High-accuracy temperature sensing and compensation networks.
Procurement Notes
Verify authenticity through authorized Analog Devices distributors or direct channels. Request Certificate of Conformance and traceability documentation. Confirm RoHS status and military qualification requirements specific to the /883C suffix before procurement. Ensure storage conditions meet moisture sensitivity levels to prevent package degradation.
Selection Notes
Select this component when low offset voltage and high matching accuracy are critical. Compare against LM194/LM394 equivalents if direct replacement is needed. Consider thermal management due to power dissipation limits. Verify package compatibility with existing PCB footprints. Evaluate noise specifications against application bandwidth requirements.
Part Context
The MAT02 series belongs to Analog Devices' Precision Monolithics line, focusing on high-performance analog building blocks. The /883C suffix indicates compliance with MIL-PRF-38534 Class K or similar high-reliability standards. This family complements other precision components like the AD590 and AD640 in complex measurement systems.
Replacement Considerations
Publicly confirmed direct replacements include the LM194 and LM394 from Texas Instruments. Verify pinout compatibility and electrical parameter margins before substitution. Alternative matched transistor arrays may require circuit redesign.
