Note 3. All voltages with respect to ground.
Note 4. The 1.8 V LDO is off (LDOE pin = “L”) and an external power is supplied to the VDD18 pin.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 3. All voltages with respect to ground.
Note 5. TVDD pin must be powered up before or at the same time with the VDD18 pin when the LDOE
pin = “L”. The power up sequence between AVDD pin and TVDD pin or between AVDD pin and
VDD18 pin is not critical.
Note 6. TVDD must not exceed VDD18±0.1 V when LDOE pin= “L”.
Note 7. When LDOE pin = “H”, the internal LDO supplies 1.8 V (typ). The power up sequences between
AVDD pin and TVDD pin is not critical.
Note 8. VREFH1-3 must not exceed AVDD+0.1 V.
Note 9. VREFL1-3 must be connected to AVSS.
Analog Input Voltage is proportional to {(VREFH) – (VREFL)}.
Vin (typ, @ 0dB) = 1.85  {(VREFH) – (VREFL)} / 3.3 [V].
