BH2227FV-E2

Digital To Analog Converters Overview

The BH2227FV-E2 is an 8-bit digital-to-analog converter (DAC) manufactured by Rohm Semiconductor. It integrates four independent voltage-output channels within a compact 14-SSOP-B package. The device utilizes an R-2R resistor ladder architecture and communicates via a standard SPI-compatible 3-wire serial interface. It operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance specifications include a settling time of 100 µs, a maximum integral nonlinearity (INL) of ±1.5 LSB, and a differential nonlinearity (DNL) of ±1 LSB. The component supports surface-mount installation and functions reliably across an industrial temperature range of -20°C to +85°C.

Digital To Analog Converters Feature Summary

• Four-channel parallel output capability with buffered voltage outputs
• Low-power consumption design suitable for battery-operated systems
• Standard 3-wire serial interface compatible with common microcontrollers

Digital To Analog Converters Applications

• Portable instrumentation requiring multi-channel signal generation
• Battery-powered consumer electronics devices
• Industrial control systems needing precise analog voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to ensure the correct tape-and-reel or cut-tape configuration matches your assembly requirements. Confirm that the 14-SSOP-B package dimensions align with your PCB footprint constraints. Check RoHS compliance status if restricted substances are mandated by your regional regulations. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Digital To Analog Converters Selection Notes

Select this component when four independent 8-bit DAC channels are required in a minimal footprint. Compare channel count against alternatives like the BH2228FV-E2 if six channels are needed. Verify that the 100 µs settling time meets your system's speed requirements. Consider the 2.7 V minimum supply voltage to ensure compatibility with your available power rails.

Digital To Analog Converters Part Context

This part belongs to the BH2227 series of 8-bit DACs from Rohm Semiconductor. It shares architectural similarities with other members such as the BH2226FV-E2 and BH2228FV-E2, differing primarily in channel count and package type. The series is characterized by its R-2R structure and low-power operation, targeting cost-sensitive embedded applications.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes within the same family include the BH2227FV-BZE2. For different channel counts, consider the BH2226FV-E2 (8 channels) or BH2228FV-E2 (6 channels), though package or pinout differences may require schematic adjustments.
