The BUSY output remains high until the conversions are completed. The MAX11014/MAX11015 then responds according to commands with the new clock mode. • CKSEL1/CKSEL0 = 01 and is then changed to another value: If waiting for the initial external trigger, the MAX11014/MAX11015 immediately exit clock mode 01, power down the ADC, and go idle. If a conversion sequence is in progress, that conver- sion is completed and then the ADC goes idle. The BUSY output remains high until the conversions are completed. The MAX11014/MAX11015 then respond according to commands with the new clock mode. • CKSEL1/CKSEL0 = 11 and is then changed to another value: If waiting for an external trigger, the MAX11014/ MAX11015 immediately exit clock mode 11, power down the ADC, and go idle. The BUSY output stays low and waits for the external trigger. If a conversion sequence is in progress, that con- version is completed and then the ADC goes idle. Applications Information Layout Considerations For the external temperature sensor to perform to spec- ifications, care must be taken to place the MAX11014/MAX11015 as close as is practical to the remote diode. Traces of DXP_ and DXN_ should not be routed across noisy lines and buses. DXP_ and DXN_ routes should be guarded by ground traces on either sides and should be routed over a quiet ground plane. Traces should be wide enough (> 10mm) to lower inductance, which tends to pick up radiated noise.
