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.
Features

D/A Converter Variable Output Range Function
BU2505FV and BU2506FV have terminals with which the upper and lower limits of the output voltage range can be changed
separately. The upper limit of the output voltage range is set with the VrefH terminal and the lower limit is set with VrefL terminal. In
general usage, the VrefH terminal is connected to the VCC terminal and the VrefL terminal is connected to the GND terminal.
When the power supply voltage on the VCC terminal is 5V, 1LSB is almost 5mV. In other cases, it is possible to achieve a
finer resolution. For example, if VrefH = 3.5V and VrefL = 1.5V, then 1LSB is almost 2mV.
