DAC7725NB

Digital To Analog Converters Overview

The DAC7725NB is a quad, 12-bit digital-to-analog converter manufactured by Burr-Brown (Texas Instruments). It features an R-2R resistor string architecture with buffered voltage outputs. The device operates on dual ±15 V analog and digital supplies within a -40°C to +85°C temperature range. Key electrical specifications include a sampling rate of 100 kS/s, a settling time of 10 µs, and differential nonlinearity of ±1 LSB. It utilizes a parallel interface for data input and is housed in a 28-pin PLCC package.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Employs an R-2R resistor string architecture to ensure stable performance across the operating temperature range.
• Supports high-speed parallel data interfaces for efficient system integration.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Test and measurement equipment needing precise analog output
• Automotive instrumentation applications

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications as availability may be limited. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, 12-bit resolution is required with buffered outputs. Verify that the parallel interface matches the host controller capabilities. Ensure the ±15 V supply rails are available in the target design environment.

Digital To Analog Converters Part Context
