ROHM BU2506FV-E2

The BU2505FV and BU2506FV ICs are 10bit R-2R type D/A converters with 10ch and 8ch outputs, respectively. Cascade connection is available, ensuring suitability for multi-channel applications. Each channel incorporates a full swing output type buffer amplifier with high speed output response characteristics, resulting in a greatly shortened D/A output settling time. The ICs also have digital input pins compatible with TTL levels, and the maximum value of the data transfer frequency is 10MHz. With the variable output range function, the upper and lower limits of the output voltage can be set separately from the power supply voltage.
