ANALOG CHARACTERISTICS
• Min/Max characteristics and specifications are guaranteed over all Operating Conditions.
• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
• VA+ = VD+ = 3 V ±10%; VA- = -2 V ±10%; AGND = DGND = 0 V; VREFIN = +1.2 V. All voltages with respect to 0 V.
• XIN = 4.096 MHz.
