AD7859AP

The AD7859AP is one member of the AD7859 family which is designed as the high speed, low power, 8-channel, 12-bit ADCs which operate from a single 3 V or 5 V power supply, this device has 10 calibration registers in all, 8 for the DAC, 1 for offset and 1 for gain. Data can be written to or read from all 10 calibration registers. In self and system calibration, the part automatically modifies the calibration registers; only if the user needs to modify the calibration registers should an attempt be made to read from and write to the calibration registers.

Features of the AD7859AP are:(1)44-pin PQFP and PLCC packages;(2)flexible parallel interface: 16-bit parallel/8-bit parallel;(3)using automatic power-down after conversion (25 mW);(4)low power;(5)system and self-calibration;(6)specified for VDD of 3 V to 5.5 V.

The absolute maximum ratings of the AD7859AP can be summarized as:(1)AVDD to AGND:-0.3 V to +7 V;(2)DVDD to DGND:-0.3 V to +7 V;(3)AVDD to DVDD:-0.3 V to +0.3 V;(4)analog input voltage to AGND:-0.3 V to AVDD+0.3 V;(5)digital input voltage to DGND:-0.3 V to DVDD+0.3 V;(6)digital output voltage to DGND:-0.3 V to DVDD+0.3 V;(7)input current to any pin except supplies:±10 mA;(8)operating temperature range commercial (A, B versions):-40°C to +85°C;(9)storage temperature range:-65°C to +150°C.
