Datasheet
D/A Converter Series for Electronic Adjustment
10bit 4ch/6ch D/A Converters
BU2507FV BU2508FV
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
