(2) Tie IOVDD to the CAP pin if IOVDD ≤ 2.0 V. (3) CMRR is measured with a common-mode signal of (VAVSS + 0.3 V) to (VAVDD – 0.3 V). (4) Set IOVDD > 3.0 V to use a crystal across the XTAL1/CLKIN and XTAL2 pins. 7.3 Recommended Operating Conditions over operating ambient temperature range (unless otherwise noted) MIN NOM MAX UNIT POWER SUPPLY Negative Charge Pump Enabled (VNCPEN(1) = 1) Analog supply voltage VAVDD to VAVSS 3.0 3.3 3.45 V VAVDD to VGND 3.0 3.3 3.45 VAVSS to VGND –0.05 0 0.05 Digital supply voltage(2) VIOVDD to VGND 1.65 3.3 3.6 V Negative Charge Pump Disabled (VNCPEN = 0) Analog supply voltage VAVDD to VAVSS 3.0 5.0 5.5 V VAVDD to VGND 1.5 2.5 5.5 VAVSS to VGND –2.75 –2.5 0.05 Digital supply voltage(2) VIOVDD to VGND 1.65 3.3 3.6 V ANALOG INPUTS VIN Differential input voltage VIN = VAINxP – VAINxN –VREF / Gain VREF / Gain V VCM Common-mode input voltage(3) VAVSS VAVDD V VAINxP, VAINxN Absolute input voltage VAVSS VAVDD V EXTERNAL REFERENCE Reference input voltage REFEXT – REFN 2.0 2.5 VAVDD – 0.5 VREF VREFN Reference negative input VAVSS V VREFEXT External reference positive input VREFN + 2.0 VREFN + 2.5 VAVDD – 0.5 V EXTERNAL CLOCK SOURCE fCLKIN External clock input frequency IOVDD > 2.7 V 0.4 16.384 25 MHz IOVDD ≤ 2.7 V 0.4 8.192 15.6 XTAL clock frequency(4) 16.384 16.5 MHz fSCLK SCLK input to derive fMOD CLKSRC bit = 1, fSCLK = fICLK, IOVDD > 2.7 V 0.2 16.384 25 MHz CLKSRC bit = 1, fSCLK = fICLK, IOVDD ≤ 2.7 V 0.2 8.192 15.6 DIGITAL INPUTS Digital input voltage GND IOVDD V TEMPERATURE TA Operating ambient temperature –40 125 °C |
