Note 1: Parameters are 100% production tested at +85°C and limits through temperature are guaranteed by design.
Note 2: The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between
(VDD - 0.5V) and (GND + 0.5V). See Digital Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics.
Note 3: Shutdown refers to the SHDN input being asserted low. Standby refers to SHDN not being asserted and all I/O inactive.
Note 4: Supply current measured with the wiper position fixed.
