D/A Converter Series for Electronic Adjustments
Standard 8bit 2ch・3ch Type
D/A Converters
BH2219FVM, BH2220FVM
No.09052EAT01
●Description
The BH2219FVM and BH2220FVM are 8bit R-2R-type D/A converters with 2 and 3 channels, respectively. A compact
package allows adjacent placement, thereby eliminating deterioration of the D/A converter due to wire pattern. Furthermore,
a built-in RESET function ensures that the output voltage at all channels is Low during power up. A broad power supply
voltage range (2.7V-5.5V) is available, providing design flexibility.
●Features
1) Compact package enabling adjacent placement
2) Built-in RESET function
3) High speed output response characteristics
4) 3-line serial interface
5) Broad power supply voltage range: 2.7V-5.5V
●Applications
DVCs, DSCs, DVDs, CD-Rs, CD-RWs
