Internal and External Temperature Sensor Specifications
(V_AVDD = 4.75V to 5.25V, V_DVDD = 3.3V, V_AVDDIO = +12.0V, V_AGND = V_DGND = 0V, V_AVSSIO = -2.0V, V_DACREF = 2.5V, V_ADCREF = 2.5V
(Internal), f_S = 400ksps, 10V analog input range set to range 1 (0 to +10V). T_A = -40°C to +105°C, unless otherwise noted. Typical values
are at T_A = +25°C.) (Note 2)
