wise noted. Typical values are at T
ANALOG POWER-SUPPLY CURRENT (Measured with digital inputs at either DGND or V
disabled, X2CLK = 0, CLK = 0 for 1.024MHz, CLK = 1 for 2.4576MHz.)
DIGITAL POWER-SUPPLY CURRENT (Measured with digital inputs at either DGND or V
disabled, X2CLK = 0, CLK = 0 for 1.024MHz, CLK = 1 for 2.4576MHz.)
