PM7545HPZ

Digital To Analog Converters Overview

The PM7545HPZ is a 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an R-2R resistor ladder architecture and operates with a single analog supply voltage ranging from 5 V to 15 V. The device utilizes a parallel interface for data input and provides an unbuffered current output. Key performance specifications include a settling time of 2 microseconds, a differential nonlinearity (DNL) of ±4 LSB, and an integral nonlinearity (INL) of ±2 LSB. It consumes 2 mA of operating current and dissipates up to 450 mW of power. The component is housed in a 20-pin Dual In-line Package (DIP) with a 0.300-inch pitch, suitable for through-hole mounting.

Digital To Analog Converters Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with existing board layouts. Confirm RoHS compliance status and lead times with authorized distributors, as availability may vary. Ensure that the parallel interface timing requirements match the host controller specifications before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with multiplying capability is required for analog signal conditioning. Consider the unbuffered current output nature, which may necessitate external amplification for voltage-mode applications. Evaluate the DIP package constraints against available PCB space and thermal dissipation requirements relative to the 450 mW power dissipation limit.

Digital To Analog Converters Part Context

The PM7545HPZ belongs to the MX7545 family of multiplying DACs from Analog Devices. This series is designed for applications requiring high accuracy and fast settling times. The HPZ variant specifically denotes the 20-pin DIP package version, distinguishing it from surface-mount options like the SOIC or PLCC packages found within the same functional family.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same package include other variants of the MX7545 family such as the MX7545JCWP+ (SOIC) if pinout compatibility allows for adapter use. Cross-reference with PM7545FR for identical electrical specifications but verify package differences. No direct pin-for-pin DIP replacements from other manufacturers are confirmed in public documentation.
