The SPI data interface keeps the digital pin count low — three wires (clock, data, chip-select) are enough to control both DACs from a microcontroller or FPGA. ## Settling time and update rate A 100 µs settling time to ±0.5 LSB means each channel can update at roughly 10 kHz before the output settles to within 1/2 LSB of the final value — adequate for DC setpoints, slow ramps, or audio sub-bands below 5 kHz. The R-2R architecture inherently offers monotonicity and low glitch energy compared to segmented or string DACs, though the 8-bit resolution limits the dynamic range to 256 steps per channel. The -30°C to 85°C operating temperature covers most indoor and industrial ambient environments, but not extended industrial (-40°C) or automotive grades — confirm the thermal profile of the end application. ROHS3 compliance means the part meets the latest EU restriction of hazardous substances directive, with no exemptions for lead or other restricted materials in the package.","metaTitle":"ROHM BH2219FVM-TR 8-bit DAC, dual, SPI, 8-MSOP","metaDescription":"Active 8-bit dual DAC with R-2R architecture, 100 µs settling time, SPI interface, 2.7-5.5 V supply, -30 to 85°C.
