LC78817

The LC78817 is 16-bit CMOS D/A converters for use in digital audio systems.They adopt a dynamic level shifting conversion technique that uses a resistor string for the upper 8 bits,PWM for the middle 4 bits,and level shifting for the lower 4 bits.

The absolute maximum ratings of the LC78817 can be summarized as:(1):the parameter is maximum supply voltage,the symbol is VDDmax,the rating is -0.3 to +7.0,the unit is V;(2):the parameter is input voltage,the symbol is VIN,the rating is -0.3 to VDD+0.3,the unit is V;(3):the parameter is output voltage,the symbol is VOUT,the rating is -0.3 to VDD+0.3,the unit is V;(4):the parameter is operating temperature,the symbol is Topr,the rating is -30 to +75,the unit is ;(5):the parameter is storage temperature,the symbol is Tstg,the rating is -40 to +125,the unit is .

The allowable operating range of the LC78817 can be summarized as:(1):the parameter is supply voltage,the symbol is VDD,the min is 3.0,the typ is 5.0,the max is 5.5,the unit is V;(2):the parameter is operating temperature,the symbol is Topr,the min is -30,the max is +75,the unit is .
