BA9201

BA9201 is an 8-bit D/A converter with a built-in reference voltage supply and internal data latch circuit.Here you can get some information about the features.First is available in DIP18 package.The second is built in reference supply voltage.Besides,input latch is included to allow simple micro-computor control.At last,the setting time is 500 ns.The typical applications include measuring and control equipment,digital audio equipment,electrical musical instruments,signal generators and servo controllers.
