BH2221FV-E2

Digital To Analog Converters Overview

The BH2221FV-E2 is an 8-bit digital-to-analog converter manufactured by ROHM Semiconductor. It features a 20-pin SSOP-B14 package and utilizes an R-2R resistor ladder architecture for signal conversion. The device supports a 3-wire serial interface with CMOS input compatibility, operating within a voltage range of 2.7 V to 5.5 V for both analog and digital supplies. It provides four independent voltage output channels with a settling time of 100 µs. Differential nonlinearity is specified at ±1 LSB, while integral nonlinearity is ±1.5 LSB. The component operates reliably across a temperature range of -20°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm compliance with RoHS directives and halogen-free requirements. Confirm that the SSOP-B14 package dimensions match the target PCB footprint constraints. Ensure the supply voltage limits align with the system design before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a multi-channel DAC with moderate resolution is required. The 8-bit resolution suits applications where high precision is not critical. Verify that the 100 µs settling time meets the system speed requirements. Consider the 2.7 V minimum supply voltage when designing low-power battery-operated devices.

Digital To Analog Converters Part Context

This part belongs to the BH222x series of digital-to-analog converters from ROHM Semiconductor. The series includes variants with different channel counts and resolutions. The BH2221FV-E2 specifically offers a balance of four channels and 8-bit accuracy in a space-efficient surface-mount package suitable for consumer electronics.

Digital To Analog Converters Replacement Considerations

Check the BH2220FV-E2 or BH2223FV-E2 for alternative channel configurations within the same family. Verify pinout compatibility before substituting with other manufacturers' 4-channel 8-bit DACs. Ensure interface protocols match if replacing with non-ROHM components.
