BH2226FV-FE2

Digital To Analog Converters Overview

The BH2226FV-FE2 is an 8-bit, 8-channel R-2R type digital-to-analog converter manufactured by ROHM Semiconductor. It features a 3-line serial interface (CSB, CLK, DI) with a maximum data transfer frequency of 10 MHz and CMOS input logic. The device operates on a power supply voltage range of 2.7 V to 5.5 V, consuming a typical current of 1.1 mA. Key electrical specifications include a settling time of 100 µs, differential non-linearity error of ±1.0 LSB, and integral non-linearity error of ±1.5 LSB. It provides buffered voltage outputs capable of sourcing or sinking up to ±1.0 mA. The component includes a built-in RESET function for initialization and supports I/O port switching. It is housed in a 16-pin SSOP-B16 package and operates within a temperature range of -20°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrated expansion port function allowing channels to be switched between D/A converter output and serial/parallel conversion modes via command.
• Built-in RESET function ensures that all channel output voltages are initialized to LOW during power-up sequences.
• High-speed output response characteristics with a settling time of 100 µs and support for serial clock frequencies up to 10 MHz.

Digital To Analog Converters Applications

• Digital Volume Controllers (DVCs)
• Digital Still Cameras (DSCs)
• DVD players
• CD-R drives
• CD-RW drives

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the package type and packaging format. The FE2 suffix indicates the SSOP-B16 package configuration. Ensure compatibility with standard surface-mount assembly processes and verify that the operating environment remains within the specified temperature and voltage limits to maintain performance reliability.

Digital To Analog Converters Selection Notes

Select this component when an application requires multiple analog outputs controlled via a simple serial interface. The 8-bit resolution and R-2R architecture provide adequate linearity for audio and control applications. Consider the 1.1 mA typical current consumption and the requirement for separate analog and digital ground routing to minimize noise interference in mixed-signal designs.

Digital To Analog Converters Part Context

This part belongs to the BH2226F series of standard 8-bit, 8-channel D/A converters from ROHM. It shares core architectural similarities with variants like the BH2226FV-E2 but differs in physical packaging and reel specifications. The series is designed for consumer electronics requiring flexible I/O and D/A functionality within a compact footprint.
