NOTES: (1) The low power mode (“power-down”) is entered when CONV remains LOW during the conversion and is still LOW at the
start of the 13th clock cycle. (2) The low power mode is exited when CONV goes HIGH. (3) When in power-down, the transition from
hold mode to sample mode is initiated by CONV going HIGH.

NOTES: (1) The serial data can be transmitted LSB first by pulling CONV LOW during the 13th clock cycle. (2) After the MSB has been
transmitted, the DATA output pin will remain LOW until CONV goes HIGH. (3) When CONV is taken LOW to initiate the LSB first transfer,
the converter enters the power-down mode.

FIGURE 5. Serial Data “LSB-First” Timing.
In contrast, the second method (clocking at a fixed rate)
means that each conversion takes X clock cycles. As the
time between conversions get longer, the converter remains
in power-down an increasing percentage of time. This re-
duces total power consumption by a considerable amount.
For example, a 50kHz conversion rate results in roughly
1/10 of the power (minus the reference) that is used at a
500kHz conversion rate.
