DatasheeDatasheett D/A Converters Standard 8bit 2ch 3ch Type BH2219FVM BH2220FVM General Description Key Specifications The BH2219FVM and BH2220FVM are 8bit R-2R-type Power Source Voltage Range: 2.7V to 5.5V D/A converters with 2 and 3 channels, respectively. A Current Consumption: 0.4mA(Typ) compact package allows adjacent placement, thereby Differential Non Linearity Error: 1.0LSB eliminating deterioration of the D/A converter due to Integral Non Linearity Error: 1.5LSB wire pattern. Furthermore, a built-in RESET function Output Current Performance: 1.0mA ensures that the output voltage at all channels is Low Settling Time: 100s(Min) during power up. A broad power supply voltage range Maximum Data Transfer Frequency: 10MHz(Max) (2.7V-5.5V) is available, providing design flexibility. Action Temperature Range: -30C to +85C Features Package W(Typ) x D(Typ) x H(Max) Compact package enabling adjacent placement Built-in RESET function High speed output response characteristics 3-line serial interface Applications DVCs, DSCs, DVDs, CD-Rs, CD-RWs MSOP8 2.90mm x 4.00mm x 0.90mm Lineup Number of channels Input method Data latch method Package Orderable Part Number 2ch BH2219FVM-TR CMOS LD method MSOP8 Reel of 3000 3ch BH2220FVM-TR Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0M2M0GZ15050-1-2 2015 ROHM Co., Ltd.

The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
