AD7228

The AD7228 has some absolute maximum ratings.(TA=+25 unless otherwise noted).The VDD to GND is -0.3V to +17V.The VDD to VSS is +0.3 V to +24 V.The digtal input voltage is -0.3 V,VDD.The VREF to GND is -0.3 V,VDD.The VOUT to GND is VSS,VDD.The power dissipation up to +75 is 1000mW.The power dissipation derates above +75 is 2.0 mW/.The operating temperature range is -55 to +125.The thermal resistance (JC):Case 1 (Q-24) is see MIL-M-38510,appendix C.Case 3 (E-28A) is see MIL-M-38510,appendix C.The storage temperature is -65 to +125.The lead temperature (soldering 10 sec) is +300.The junction temperature is +175.Outputs may be shorted to any voltage in the range Vss to VDD provided that the power disspitation of the package is not exceeded.Typical short circuit for a short to VSS is 50 mA.

The AD7228 has some recommened operating conditions.Operating voltage range for dual supply:the positive supply (VDD) is +10.8 V to +16.5V.The negative supply (VSS) is -4.5V to -5.5V.The reference voltage (VREF) is +2.0V to +10.0V.Operating voltage range for single supply:the positive supply (VDD) is +13.5V to +16.5V.The negative supply (VSS) is 0V.The reference voltage (VREF) is +10V.
