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.

4: VDD = 5V DC ±500 mVP-P @ 1 kHz, see test circuit Figure 1-4.

5: Maximum clock frequency specification must be met.

6: VREF = 400 mV, VIN = 0.1V to 4.9V @ 1 kHz

7: MSOP devices are only specified at 25°C and +85°C.

8: For slow sample rates, see Section 5.2.1 “Maintaining Minimum Clock Speed” for limitations on clock frequency.

9: 4.5V - 5.5V is the supply voltage range for specified performance
