PM7548FR

Digital To Analog Converters Overview

The PM7548FR is a 12-bit Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. It features an R-2R resistor ladder architecture and accepts parallel binary or offset binary input data via an 8-bit loading interface. The device operates with dual power supplies ranging from 4.75 V to 5.25 V for digital logic and 11.4 V to 15.75 V for analog circuits. It provides unbuffered current output with a maximum linear error of 0.012%. Packaged in a hermetically sealed ceramic DIP-20, it supports an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• 12-bit resolution with R-2R architecture
• Hermetically sealed ceramic DIP-20 package
• Parallel 8-bit input interface
• Dual supply operation: 5V digital, ±15V analog

Digital To Analog Converters Applications

• Military and aerospace systems requiring radiation hardness
• High-reliability industrial control equipment
• Precision measurement instrumentation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'FR' against the official Analog Devices datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides documentation confirming the hermetic seal integrity, as this is critical for the specified military/aerospace grade packaging. Check for RoHS compliance status if required by the end application.

Digital To Analog Converters Selection Notes

Select the PM7548FR when a hermetically sealed, high-reliability 12-bit DAC is required for harsh environments. Compare settling time and linearity specifications against system requirements. Consider the PDIP-20 variant (AD7548KNZ) for non-hermetic applications or the PLCC variant (AD7548KPZ) for surface mount needs within the same functional family.

Digital To Analog Converters Part Context

This component belongs to the AD7548/MX7548 family of CMOS 12-bit DACs. The PM prefix typically denotes a military-grade version produced under specific quality standards. The FR suffix indicates the specific package style and thermal rating within the manufacturer's coding system.

Digital To Analog Converters Replacement Considerations

Direct replacements include AD7548KNZ (PDIP-20, commercial/industrial grade) and MX7548JCWP+ (SOIC-20). For hermetic requirements, verify availability of other CERDIP variants from the same family.
