DACs for Electronic Adjustment
High-precision 10bit
8ch/10ch D/A Converters
BU2506FV,BU2505FV
●Description
BU2506FV and BU2505FV ICs are high performance 10bit R-2R type DACs with 8ch and 10ch outputs, respectively.
Cascade connection is possible, ensuring suitability with multi-channel applications. Each channel incorporates a full swing
output-type buffer amplifier with high speed output response characteristics, resulting in a greatly shortened wait time.
The ICs also utilize the TTL level input method, and with the RESET pin the output voltage can be kept in the lower reference
voltage range.
●Features
1) High performance, multi-channel R-2R-type 10bit D/A converter built-in
(BU2506FV: 8 channels, BU2505FV: 10 channels)
2) Full swing output type buffer amplifier incorporated at each output channel
3) The RESET terminal can keep the output voltage at all channels within the lower reference voltage range
4) Digital input compatible with TTL levels
5) 14bit 3-line serial data + RESET signal input (address 4bit + data 10bit)
6) Cascade connection available
7) LSB first / MSB first of 10bit data can be changed by the REVERSE terminal
8) Compact package: 0.65mm pitch, 20 pins (SSOP-B20)
●Applications
DVDs, CD-Rs, CD-RWs, Digital cameras
