DACs for Electronic Adjustment
High-precision 10bit
4ch/6ch D/A Converters
BU2508FV, BU2507FV
●Description
BU2508FV and BU2507FV ICs are high performance 10bit R-2R-type DACs with 4ch and 6ch outputs, respectively.
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.
●Features
1) High performance, multi-channels R-2R-type 10bit D/A converter built-in
(BU2508FV: 4 channels, BU2507FV: 6 channels)
2) Full swing output type buffer amplifier incorporated at each output channel
3) The RESET terminal can keep the voltage of 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) Compact package: 14 pins, 0.65mm pitch (SSOP-B14)
●Applications
DVDs, CD-Rs, CD-RWs, digital cameras
