BH2220FVM-TR

The BH2220FVM-TR is an 8-bit R-2R digital-to-analog converter (DAC) from ROHM Semiconductor featuring three independent voltage-buffered output channels. It utilizes a 3-line serial interface (SPI) for data transfer and operates from a supply voltage range of 2.7V to 5.5V. Key electrical characteristics include a typical settling time of 100 µs, maximum integral non-linearity (INL) of ±1.5 LSB, and differential non-linearity (DNL) of ±1.0 LSB. The device consumes a typical supply current of 0.4 mA and can source or sink up to ±1.0 mA per output.

The DAC incorporates a built-in RESET function that ensures all output voltages are low during power-up, providing predictable startup behavior. The R-2R architecture offers monotonic performance and is well-suited for applications requiring multiple analog outputs. The device is housed in a compact 8-MSOP (MSOP-8) surface-mount package, enabling space-efficient PCB layouts.

Typical applications include digital video cameras (DVCs), digital still cameras (DSCs), DVD players, CD-R/RW drives, and other consumer electronics requiring precise analog voltage generation. The wide operating temperature range of -30°C to 85°C allows use in various environmental conditions.
