BD79702FV-LBE2

Digital To Analog Converters Overview

The BD79702FV-LBE2 is an industrial-grade, 8-bit, 4-channel R-2R Digital-to-Analog Converter manufactured by ROHM Semiconductor. It features a wide supply voltage range of 2.7V to 5.5V and supports dual output voltages (3V/5V) for design flexibility. The device utilizes a 3-wire SPI interface with a maximum update rate of 30MHz and a settling time of 4.5µs. Operating within a temperature range of -40°C to 125°C, it is housed in a compact SSOP-B14 package measuring 5.0x6.4mm.

Digital To Analog Converters Feature Summary

• Compact SSOP-B14 package enables adjacent placement near target adjustment points to minimize board wiring degradation.
• Built-in initial zero hold function ensures stable output states upon power-up or reset.
• High-speed output response characteristics support rapid signal updates via the 3-wire serial interface.

Digital To Analog Converters Applications

• Industrial equipment requiring precise analog signal generation
• Process control systems needing multi-channel voltage regulation
• Automotive instrumentation operating under extended temperature conditions

Digital To Analog Converters Procurement Notes

Verify the specific suffix LBE2 against official ROHM documentation to confirm package type and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard taping packaging requirements. Cross-reference the part number with current lifecycle status to confirm long-term availability for industrial applications.

Digital To Analog Converters Selection Notes

Select this component when four independent 8-bit DAC channels are required within a single IC. The wide supply voltage range accommodates various logic levels. Consider the 30MHz update rate and 4.5µs settling time for high-speed application requirements. Verify that the SSOP-B14 footprint fits the PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the BD7970x series of 8-bit D/A converters designed for the industrial market. It shares architectural similarities with the BD79700FVM-LB and BD79703FV-LB but differs in channel count and package configuration. The series emphasizes long-term support and reliability for critical industrial deployments.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other members of the BD7970x family such as the BD79700FV-LB (2-channel) or BD79703FV-LB (6-channel), provided pin compatibility and channel requirements allow. Verify package dimensions and electrical parameters before substitution.
