PM7628FSR

Digital To Analog Converters Overview

The PM7628FSR is a dual 8-bit buffered multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an R-2R resistor ladder structure and operates with a supply voltage range of 4.75V to 15V for analog circuits and 5V to 5.25V for digital logic. The device provides two independent channels within a 20-pin SOIC surface-mount package. Key performance specifications include a settling time of 300ns, integral non-linearity of ±0.5LSB to ±1LSB, and an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 8-bit digital-to-analog conversion paths
• Buffered output design suitable for driving external loads without additional amplification
• Multiplying capability allowing reference input scaling for variable output ranges

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Portable instrumentation utilizing battery-powered low-voltage operation
• Data acquisition systems needing multi-channel signal conditioning

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'FSR' against official Analog Devices documentation to confirm the 20-SOIC package and commercial temperature grade. Ensure compatibility with system voltage requirements, as the digital section requires 5V logic levels while the analog section supports up to 15V. Confirm end-of-life status or obsolescence notifications prior to final procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required for space-constrained designs using surface-mount technology. Consider the 300ns settling time for applications with moderate speed requirements. Evaluate the ±0.5LSB to ±1LSB linearity specification against system accuracy needs. Ensure the host microcontroller can interface with the parallel data bus architecture utilized by this DAC family.
