Data Sheet ADAR1000 SPECIFICATIONS
AVDD1 = −5 V, AVDD3 = +3.3 V, TA = 25°C, and the device is programmed to the maximum channel gain and the nominal bias conditions, unless otherwise noted. Nominal bias register settings: Register 0x034 = 0x08, Register 0x035 = 0x55, Register 0x036 = 0x2D, and Register 0x37 = 0x06. Low power bias register settings: Register 0x034 = 0x05, Register 0x035 = 0x1A, Register 0x036 = 0x2A, and Register 0x37 = 0x03.
