PM7528BR/883C

Digital To Analog Converters Overview

The PM7528BR/883C is a dual, high-precision 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes an R-2R resistor ladder architecture and features parallel data input with 4-bit loading. The device operates on analog and digital supply voltages ranging from 5V to 15V. Key electrical specifications include a settling time of 0.25 microseconds and a maximum linear error of 0.024%. It is housed in a 20-pin ceramic Leadless Ceramic Chip Carrier (LCC) package designed for military or aerospace environments.

Digital To Analog Converters Part Context

This component belongs to the PM7528 family of precision DACs. The suffix /883 indicates compliance with MIL-PRF-38535 standards for hybrid microcircuits, signifying its qualification for use in defense and space applications requiring enhanced reliability and radiation hardness compared to commercial variants.

Digital To Analog Converters Replacement Considerations

Direct pin-for-pin replacements within the same ceramic LCC-20 form factor should be verified against specific MIL-PRF-38535 lot traceability requirements. Commercial equivalents like the MX7528 series differ in package type and environmental rating.
