BA9211

BA9211 is a kind of 10-bit D/A converter with a built-in reference voltage supply.The reference voltage supply circuit is an independent block and it can use an external reference power supply.These ICs have a very fast conversion time.They are for use on machines with a digital-to-analog control system.

Here you can get some information about the BA9211  features.First is available in DIP22 package.The second is built in reference supply voltage.Besides,the settting speed is as low as 250 ns.At last,it can be used for multiplying.The typical applications include programmable gain amplifiers,programmable attenuators,electrical musical insrtruments,signal generators,servo controllers and digitally controlled power supply.

What comes next is about the BA9211  absolute maximum ratings (T_a=25).The V_CC (power supply voltage) is +5.5 V.The V_EE (power supply voltage) is -15 V.The power dissipation (P_d) is 600 mW.The V₁₆,V₁₇ (Ref voltage V₁₆,V₁₇) is from V_EE to V_CC V.The V_IN (logic input pin) is from -5 to V_CC V.The T_opr (operating temperature) is from -20 to +70.The T_stg (storage temperature) is from -55 to +125.

The following is about the BA9211  eletrical characteristics (T_a=25,V_CC=+5 V,V_EE=-12 V).The resolving power is 10 bit.The monotonicity is 10 bit.The typical TCI _FS (temperature-to-current coefficient,full scale) is ±50 ppm/.The typical TCV_REF (Ref voltage to temperature characteristics) is ±50 ppm/.The minimum V_CC (power supply voltage) is 4.75 V,the typical is 5.0 V and the maximum is 5.25 V when V_OUT=0 V.The minimum V_EE (power supply voltage) is -10.8 V,the typical is -12.0 V and the maximum is -13.2 V when V_OUT=0 V.The typical NFS (noise factor) is 0.2 mVrms and the maximum is 1 mVrms at R=1 k.
