AD7821KP

The AD7821KP is a high speed, 8-bit, sampling,analog-to-digital converter that offers improved performance over the popular AD7820.It offers a conversion time of 660 ns (vs. 1.36 ms for the AD7820) and 100 kHz signal bandwidth (vs. 6.4 kHz).The sampling instant is better defined and occurs on the falling edge of WR or RD.

The absolute maximum ratings of the AD7821KP can be summarized as:(1):the parameter is VDD to GND,the rating is -0.3 to +7,the unit is V;(2):the parameter is VSS to GND,the rating is +0.3 to +7,the unit is V;(3):the parameter is digital iInput voltage to GND,the rating is -0.3 to VDD + 0.3 ,the unit is V;(4):the parameter is digital output voltage to GND,the rating is -0.3 to VDD + 0.3,the unit is V;(5):the parameter is VREF(+) to GND,the rating is VSS0.3V to  VDD+0.3,the unit is V;(6):the parameter is VREF() to GND,the rating is VSS0.3V to  VDD+0.3,the unit is V;(7):the parameter is VIN to GND,the rating is VSS0.3V to  VDD+0.3,the unit is V;(8):the parameter is operating temperature range commercial,the rating is -40 to +85,the unit is ;(9):the parameter is storage temperature range,the rating is -65 to +150,the unit is ;(10):the parameter is lead temperature(10 sec max),the rating is +300,the unit is ;(11):the parameter is power dissipation (any package) to +75,the rating is 450,the unit is mW;(12):the parameter is derates above +75 by,the rating is 6,the unit is mW/.
