BH2219FVM-TR

Digital To Analog Converters Overview

The BH2219FVM-TR is an 8-bit, 2-channel digital-to-analog converter (DAC) manufactured by Rohm Semiconductor. It utilizes an R-2R resistor ladder architecture and features a buffered voltage output type. The device communicates via a 3-wire serial interface with a maximum clock frequency of 10 MHz. It operates within a supply voltage range of 2.7 V to 5.5 V for both analog and digital sections. Key electrical parameters include a settling time of 100 µs, a maximum integral nonlinearity (INL) of ±1.5 LSB, and a maximum differential nonlinearity (DNL) of ±1 LSB. The component is housed in an 8-MSOP package and supports an operating temperature range from -30°C to +85°C.

Digital To Analog Converters Feature Summary

• Compact MSOP8 packaging designed for minimal board space and proximity installation to reduce signal degradation.
• Built-in initial hold function maintains the DAC output at a low level upon power-on to prevent erroneous operations.
• Supports high-speed response characteristics with a 10 MHz serial interface clock capability.

Digital To Analog Converters Applications

• Portable electronic devices requiring compact data conversion solutions.
• Industrial control systems utilizing serial communication interfaces.
• Consumer electronics where small form factor and low power consumption are critical.

Digital To Analog Converters Procurement Notes

Verify the specific suffix '-TR' indicates tape and reel packaging when sourcing components. Confirm that the 8-MSOP package dimensions align with your PCB footprint requirements. Ensure the supply voltage constraints between 2.7V and 5.5V match your system design. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with two independent channels is required. Consider the R-2R architecture for its straightforward implementation. Evaluate the 100 µs settling time against your application's update rate needs. The wide supply voltage range offers flexibility for various power supply designs without additional regulation.

Digital To Analog Converters Part Context

This part belongs to the BH2219 series of 8-bit D/A converters. It is distinct from the BH2220FVM, which provides three channels instead of two. Both share similar architectural features but differ in channel count. The BH2219FVM-TR is specifically packaged for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

The BH2219FVM is the non-tape variant of the same functional component. For applications requiring three channels, the BH2220FVM series serves as a functional alternative within the same product family. Verify pin compatibility before substituting any related models.
