General Description
The BU2507FV and BU2508FV ICs are 10bit R-2R type D/A converters with 6ch and 4ch outputs, respectively.
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.

FEATUREs
