The LTC1291 is a data acquisition component which
contains the following functional blocks:
1. 12-bit successive approximation capacitive A/D
converter
2. Analog multiplexer (MUX)
3. Sample-and-hold (S/H)
4. Synchronous, half duplex serial interface
5. Control and timing logic

being transmitted on the falling CLK edge and captured on
the rising CLK edge in both transmitting and receiving
systems.
DIGITAL CONSIDERATIONS
Serial Interface
The LTC1291 communicates with microprocessors and
other external circuitry via a synchronous, half duplex,
four-wire serial interface (see Operating Sequence). The
clock (CLK) synchronizes the data transfer with each bit

The input data is first received and then the A/D conversion
result is transmitted (half duplex). Because of the half
duplex operation D
