PM7548GP

Digital To Analog Converters Overview

The PM7548GP is a monolithic 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It utilizes an R-2R resistor ladder architecture and accepts parallel binary or offset binary input data. The device features hermetically sealed ceramic dual in-line packaging (CDIP-20). It operates with analog and digital supply voltages ranging from 4.75 V to 5.25 V or 11.4 V to 15.75 V. Key electrical specifications include a settling time of 1 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. The component supports a maximum analog output voltage of 15 V and functions within a temperature range of -40 °C to +85 °C.

Digital To Analog Converters Part Context

The PM7548GP belongs to the PM7548 family of high-reliability DACs. This series is distinguished by its hermetic sealing, which ensures environmental stability for defense and space applications. It serves as a specialized variant of the commercial AD7548/MX7548 lines, offering enhanced durability without altering the core digital interface or conversion logic.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements include the AD7548JNZ and MX7548JEWP+. However, these commercial variants lack the hermetic sealing and specific reliability qualifications of the PM7548GP. Substitution requires verification that the application environment does not mandate hermetic protection.
