NOTE 4: Apply a 1 dBFS 10-KHz triangle wave at AIN+ and AIN with an internal bandgap reference and ADC reference enabled, and BIASREF
enabled at AVDD/2. Any additional load at BIASREF or VREF may require additional current.
NOTE 5: Wake-up time is from the power-down state to accurate ADC samples being taken and is specified for MODE = AGND with external
reference sources applied to the device at the time of release of power-down, and an applied 40-MHz clock. Circuits that need to power
up are the bandgap, bias generator, ADC, and SHA.
NOTE 6: External reference values are listed in the
Recommended Operating Conditions Table
