BH2228FV-E2

Digital To Analog Converters Overview

The BH2228FV-E2 is an 8-bit, 6-channel digital-to-analog converter (DAC) manufactured by ROHM Semiconductor. It utilizes an R-2R resistor ladder architecture and features a 3-wire serial interface with CMOS-compatible inputs. The device operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital sections. Key performance metrics include a settling time of 100 µs, a typical operating current of 500 µA, and a maximum power dissipation of 400 mW. Linearity specifications are defined by a differential nonlinearity (DNL) of ±1 LSB and an integral nonlinearity (INL) of ±1.5 LSB. It is housed in a compact SSOP-14 surface-mount package and functions within a temperature range of -20°C to +85°C.

Digital To Analog Converters Feature Summary

• Six independent voltage output channels providing simultaneous digital-to-analog conversion capabilities.
• Low-power operation suitable for battery-driven applications with minimal quiescent current consumption.
• Compact SSOP-14 packaging designed for space-constrained printed circuit board layouts.

Digital To Analog Converters Applications

• Audio equipment tuning circuits requiring multi-channel signal adjustment.
• Portable electronic devices utilizing low-voltage power supplies.
• Industrial control systems needing precise analog voltage references.

Digital To Analog Converters Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with current environmental standards and material declarations. Ensure that the SSOP-14 footprint matches the target PCB design guidelines. Confirm that the 3-wire interface timing requirements align with the host microcontroller's serial communication protocols before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when six independent 8-bit DAC outputs are required within a limited pin count. The 2.7 V to 5.5 V supply range accommodates various single-supply logic families. Consider the 100 µs settling time for bandwidth limitations in the application. Compare power dissipation limits against thermal constraints if multiple channels operate at high loads simultaneously.

Digital To Analog Converters Part Context

This part belongs to the BH2228FV series of multi-channel DACs from ROHM Semiconductor. It shares architectural similarities with other members like the BH2227FV-E2 but offers a higher channel count within the same 14-pin form factor. The series is characterized by its R-2R structure and compatibility with standard serial interfaces, targeting cost-sensitive consumer and industrial electronics.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the BH2227FV-E2, which provides four channels in the same SSOP-14 package. For applications requiring fewer channels, the BH2227FV-E2 serves as a compatible alternative. Verify pinout compatibility and electrical parameters before swapping with other series members.
