Notes:
1. Filter characteristic scales with output sample rate.
2. The analog modulator samples the input at 6.144 MHz for an output sample rate of 48 kHz. There is
no rejection of input signals which are multiples of the sampling frequency ( n x 6.144 MHz ±21.7kHz
where n = 0,1,2,3...).

Notes: 3. Any Pin except supplies. Transient currents of up to +/- 100 mA on the analog input pins will not
cause SCR latch-up.
4. The maximum over/under voltage is limited by the input current.
WARNING:Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
