Note 1. All voltages with respect to ground.
Note 2. The 1.8V 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 1. All voltages with respect to ground.
Note 3. TVDD must be powered up before VDD18 when the LDOE pin = “L”. The power up sequence between
AVDD and TVDD or AVDD and VDD18 is not critical.
Note 4. TVDD must not exceed VDD18±0.1V when LDOE pin= “L”.
Note 5. When LDOE pin = “H”, the internal LDO supplies 1.8V (typ). The power up sequences between AVDD
and TVDD is not critical.
Note 6. VREFH1~4 pin must not exceed AVDD+0.1V.
Note 7. VREFL1-4 pins must be connected to AVSS.
Analog Input Voltage is proportional to {(VREFH) – (VREFL)}.
Vin (typ, @ 0dB) = 2.8  {(VREFH) – (VREFL)} / 5 [V].
