APPLICATIONS INFORMATION
Sleep Mode
The ADCs enter sleep mode after a conversion is complete
(tCONV) if the SLP bit is set to a logic 1. The ADCs draw
only 7μA in sleep mode, provided that none of the digital
inputs are switching. When the LTC2301/LTC2305 are
properly addressed, the ADCs are released from sleep
mode and require 200ms (tREFWAKE) to wake up and charge
the respective 2.2μF and 10μF bypass capacitors on the
VREF and REFCOMP pins. A new conversion should not be
initiated before this time, as shown in Figure 11.
Acquisition
The LTC2301/LTC2305 begin acquiring the input signal at
different instances depending on whether a read or write
operation is being performed. If a read operation is being
performed, acquisition of the input signal begins on the
rising edge of the 9th clock pulse following the address
frame, as shown in Figure 12a.
If a write operation is being performed, acquisition of the
input signal begins on the falling edge of the sixth clock
cycle after the DIN word has been shifted in, as shown in
Figure 12b. The LTC2301/LTC2305 will acquire the signal
from the input channel that was most recently programmed
by the DIN word. A minimum of 240ns is required to acquire
the input signal before initiating a new conversion.
Board Layout and Bypassing
To obtain the best performance, a printed circuit board with
a solid ground plane is required. Layout for the printed
board should ensure digital and analog signal lines are
