Energy per Conversion 8 nJ/ sample TEMPERATURE RANGE Specified Performance TMIN to TMAX −40 +125 °C 1 The acquisition phase is the time available for the input sampling capacitors to acquire a new input with the ADC running at a throughput rate of 2 MSPS. 2 A throughput rate of 2 MSPS can only be achieved with turbo mode enabled and a minimum SCK rate of 75 MHz. Refer to Table 4 for the maximum achievable throughput for different modes of operation. 3 Transient response is the time required for the ADC to acquire a full-scale input step to ±1 LSB accuracy. 4 The minimum and maximum values are guaranteed by characterization, but not production tested.
TIMING SPECIFICATIONS
VDD = 1.71 V to 1.89 V; VIO = 1.71 V to 5.5 V; VREF = 5 V; all specifications TMIN to TMAX, high-Z mode disabled, span compression disabled, turbo mode enabled, and sampling frequency fS = 2 MSPS.
