Power Shutdown Operating Sequence
Example: Differential Inputs (CH4
+, CH5), Unipolar Mode and MSB-First Data
all logical ones will be shifted out followed by logical
zeroes till CS goes high. Then the DOUT line will go into its
high impedance state. The LTC 1293/4/6 will remain in the
shutdown mode till the next CS cycle. There is no warm-
up or wait period required after coming out of the power
shutdown cycle so a conversion can commence after CS
goes low (see Power Shutdown Operating Sequence). The
LTC1296 has a System Shutdown Output pin (SSO) which
will go low when power shutdown is activated. The pin will
stay low till next CS cycle.
Microprocessor Interfaces
The LTC1293/4/6 can interface directly (without external
hardware) to most popular microprocessors (MPU) syn-
chronous serial formats (see Table 1). If an MPU without
a dedicated serial port is used, then three of the MPU’s
parallel port lines can be programmed to form the serial
link to the LTC1293/4/6. Included here are one serial
interface example and one example showing a parallel
port programmed to form the serial interface.
