Notice: Stresses above those listed under “Maximum
ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification
is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.

Note 1: This specification is established by characterization and not 100% tested.
2: See characterization graphs that relate converter performance to VREF level.
3: VIN = 0.1V to 4.9V @ 1 kHz.
5: Maximum clock frequency specification must be met.
6: VREF = 400 mV, VIN = 0.1V to 4.9V @ 1 kHz.
7: TSSOP devices are only specified at 25°C and +85°C.
8: For slow sample rates, see Section 5.2 “Driving the Analog Input” for limitations on clock frequency.
9: 4.5V - 5.5V is the supply voltage range for specified performance.
