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
