These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. recommended operating conditions power supplies MIN TYP MAX UNIT Analog supply voltage, AVDD (see Note 1) 2.7 5.5 V Digital supply voltage, DVDD (see Note 1) 2.7 5.5 V NOTE 1: Abs (AVDD – DVDD) < 0.5 V analog inputs MIN TYP MAX UNIT Analog input voltage, AIN AGND VREF V Reference input voltage REF DVDD = 3.3 V to 2.7 V 55% AVDD AVDD V Reference input voltage, REF DVDD = 5.5 V to 4.5 V 60% AVDD AVDD V digital inputs MIN TYP MAX UNIT High-level input voltage, VIH DVDD = 2.7 V to 5.5 V 2.1 V Low-level input voltage, VIL DVDD = 2.7 V to 5.5 V 0.8 V Input SCLK frequency DVDD = 5.5 V to 4.5 V 20 MHz Input SCLK frequency DVDD = 3.6 V to 2.7 V 1 10 MHz SCLK pulse duration clock high t (SCLKH) DVDD = 5.5 V to 4.5 V 23 ns SCLK pulse duration, clock high, tw(SCLKH) DVDD = 3.6 V to 2.7 V 46 ns SCLK pulse duration clock low t (SCLKL) DVDD = 5.5 V to 4.5 V 23 ns SCLK pulse duration, clock low, tw(SCLKL) DVDD = 3.6 V to 2.7 V 46 ns electrical characteristics,over recommended operating free-air temperature range, supply voltages, and reference voltages (unless otherwise noted) digital specifications (SDOUT at 25 pF) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Logic inputs IIH High-level input current DVDD = 5 V, VI = 5 V 1 µA IIL Low-level input current DVDD = 5 V, VI = 0 V –1 µA CI Input capacitance Control inputs 5 15 pF Logic outputs |
