A/D CONVERTER CHARACTERISTICS
All typical values are for 25°C ambient temperature and 5 V at pin Vcc. Maximum and minimum specifications are over the
recommended operating conditions. All voltages are referred to the voltage at pin Vss unless otherwise specified. All bits in control
registers are “0” unless otherwise specified.
unless otherwise specified. 400kHz TTL input at SCL unless otherwise specified. SDA pulled to Vcc through an external 2kΩ resistor
unless otherwise specified. 2-wire interface in “standby” (see notes 1 and 2 on page 22), unless otherwise specified. WP, A0, A1, and A2
floating unless otherwise specified.
Notes: 1. “LSB” is defined as V(VRef)/63, “Full Scale” is defined as V(VRef).
