SLEEP MODE
The LTC2365/LTC2366 provide a sleep mode to conserve
power during inactive periods. Upon power-up, holding
CS HIGH initializes the ADC to sleep mode. In sleep mode,
all bias circuitry is shut down and only leakage currents
remain (0.1µA typ).
Entering Sleep Mode
The ADC achieves the fastest sampling rate in operational
mode (full power-up). The device can also be put into sleep
mode for power savings during inactive periods. To force
the LTC2365/LTC2366 into sleep mode, the user can inter
-
rupt the
conversion process by bringing CS HIGH
between
the 2nd and 10th falling edges of SCK (see Figures 13 and
14). If CS is brought HIGH after the 10th falling edge and
before the 16th falling edge, the device remains powered
up, but the conversion is terminated and SDO returns to
the high impedance state.
