... BH2226FV,BH2226F ●Description The BH2226FV,BH2226F is an 8bit R-2R-type D/A converter with 8 channels. The D/A converter output and serial / parallel conversion function can be switched with one command, and a built-in RESET function ensures that the output voltage at all channels is Low during power up. A broad power supply voltage range (2.7V-5.5V) is available, providing design flexibility. ● ...

... BH2226FV,BH2226F ・Command Transmission Procedures Carry out the following after power on and just after external reset: (1) Power Down Release (2) I/O D/A Select (3) I/O Status Set Note: When power is started, the power on reset is activated and the internal register initialized. However, as shown in the figure above, in area (a), if CSB cannot be made High and noise is introduced in the control line an error may occur when setting during the rising CSB signal ...

... BH2226FV,BH2226F ●Operation Notes (1) Numbers and data in entries are representative design values and are not guaranteed values of the items. (2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further when using them. When modifying externally attached component constants before use, determine them so that they have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for static characteristics but also including transient characteristics ...
