Notes:
1. The Si2457/34/15/04 specifications are guaranteed when the typical application circuit (including component tolerance)
and any Si2457/34/15/04 and any Si3018 are used. See "2. Typical Application Schematic" on page 11.
2. All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions.
Typical values apply at nominal supply voltages and an operating temperature of 25 °C unless otherwise stated.
3. The digital supply, VD, operates from 3.0 to 3.6 V.
