BU2506FV-E2

Digital To Analog Converters Overview

The BU2506FV-E2 is an eight-channel digital-to-analog converter manufactured by ROHM Semiconductor. It features a 10-bit resolution and utilizes an R-2R resistor ladder structure for conversion. The device operates with both analog and digital supply voltages ranging from 4.5 V to 5.5 V. It employs a 3-wire serial interface compatible with TTL input levels. Key performance metrics include a settling time of 7 µs, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±3.5 LSB. The output type is voltage buffered, and the component is housed in a 20-pin SSOP package suitable for surface mount installation.

Digital To Analog Converters Feature Summary

• Eight independent DAC channels integrated into a single monolithic IC
• Voltage buffered outputs providing direct drive capability without external amplification
• TTL-compatible 3-wire serial interface for simplified microcontroller connection
• R-2R ladder architecture ensuring stable linearity characteristics

Digital To Analog Converters Applications

• Multi-channel signal generation in industrial control systems
• Programmable voltage reference distribution in test equipment
• Audio level adjustment circuits requiring multiple independent channels
• Instrumentation front-ends needing precise analog voltage setting

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific revision. Check for obsolescence notices as availability may be limited to existing stock. Ensure packaging specifications align with automated assembly requirements if applicable.

Digital To Analog Converters Selection Notes

Select this component when eight isolated analog outputs are required from a single digital source. The 10-bit resolution suits applications not demanding high precision but requiring cost-effective multi-channel conversion. Verify that the 7 µs settling time meets system timing constraints. Consider the SSOP-20 footprint during PCB layout planning.

Digital To Analog Converters Part Context

This part belongs to the BU2506 series of multi-channel DACs from ROHM Semiconductor. It shares architectural similarities with other members like the BU2507FV-E2 but differs in channel count and pin configuration. The series targets general-purpose analog output applications where space efficiency and moderate performance are prioritized over high-speed or high-resolution capabilities.

Digital To Analog Converters Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative multi-channel DACs from other manufacturers only if they match the 8-channel requirement, 10-bit resolution, and SSOP-20 package dimensions. Cross-reference electrical parameters carefully before substitution.
