Datasheet
D/A Converter Series for Electronic Adjustment
10bit 8ch/10ch D/A Converters
BU2505FV BU2506FV
General Description
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.
