BH2220FVM-TR

Digital To Analog Converters Overview

The BH2220FVM-TR is an 8-bit, 3-channel digital-to-analog converter manufactured by Rohm Semiconductor. It utilizes an R-2R resistor ladder architecture and features a buffered voltage output type without differential capability. The device operates on a single power supply ranging from 2.7V to 5.5V for both analog and digital sections. It communicates via a standard SPI interface with a maximum settling time of 100µs. Integral non-linearity and differential non-linearity are specified at ±1.5 LSB and ±1 LSB respectively. The component is housed in an 8-MSOP surface-mount package and supports an operating temperature range from -30°C to +85°C.

Digital To Analog Converters Feature Summary

• Three independent 8-bit DAC channels integrated within a single compact package
• SPI serial interface compatibility for straightforward digital control
• Buffered voltage outputs providing stable signal driving capability
• Wide single-supply operation supporting low-voltage portable applications

Digital To Analog Converters Applications

• Portable consumer electronics requiring multi-channel signal generation
• Battery-powered devices utilizing wide voltage range operation
• Industrial control systems needing isolated analog outputs
• Audio equipment requiring precise digital-to-analog conversion stages

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as the TR designation indicates tape and reel format. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure ESD handling protocols are followed during storage and assembly due to the sensitive CMOS input structure inherent to the SPI interface.

Digital To Analog Converters Selection Notes

Select this component when multiple low-resolution analog outputs are required from a microcontroller with limited pins. The R-2R architecture offers predictable performance across the operating temperature range. Consider the 100µs settling time against system update rates. Verify that the 8-MSOP footprint matches the PCB layout constraints and that the 2.7V minimum supply aligns with the system battery profile.

Digital To Analog Converters Part Context

This part belongs to the BH2220 series of 8-bit D/A converters featuring 3, 4, 6, 8, 10, or 12 channels. These devices share a common R-2R architecture and SPI interface but vary in channel count and pinout configurations. The BH2220FVM-TR specifically provides three channels in a small outline package, distinguishing it from higher-channel variants like the BH2221 or BH2222 which offer more outputs in larger packages.

Digital To Analog Converters Replacement Considerations

Direct replacements must match the 8-bit resolution, 3-channel count, and SPI interface. Check pin compatibility for the 8-MSOP package. Alternative Rohm parts include other members of the BH2220 family with different channel counts. Verify that substitute components maintain the same 2.7V to 5.5V supply range and -30°C to +85°C temperature specifications.
