1 Temperature range for A and B versions is −40°C to +85°C; temperature range for S version is −55°C to +125°C.

2 Operational from VDD = 2.0 V.

3 See the Terminology section.

4 Maximum B and S version specifications apply as typical figures when VDD = 5.25 V.

5 Guaranteed by characterization.

6 For A version: fSAMPLEMAX = 1 MSPS; B and S versions: fSAMPLEMAX = 600 kSPS.

7 See the Power vs. Throughput Rate section.
