LTC1292/LTC1297

TEST CIRCUITS
Voltage Waveforms for ten
The LTC1292/LTC1297 are data acquisition components
which contain the following functional blocks:
1. 12-Bit Succesive Approximation Capacitive A/D
Converter
2. Differential Input
3. Sample-and-Hold (S/H)
4. Synchronous, Half-Duplex Serial Interface
5. Control and Timing Logic
DIGITAL CONSIDERATIONS
Serial Interface
The LTC1292/LTC1297 communicate with microproces-
sors and other external circuitry via a synchronous, half-
duplex, three-wire serial interface (see Operating Se-
quence). The clock (CLK) synchronizes the data transfer
with each bit being transmitted on the falling CLK edge.
The LTC1292/LTC1297 do not require a configuration
input word and have no DIN pin. They are permanently
configured to have a single differential input and to per-
form a unipolar conversion. A falling CS initiates data
transfer. To allow the LTC1297 to recover from the power
shutdown mode, tsuCS has to be met. Then the first CLK
pulse enables DOUT. After one null bit, the A/D conversion
result is output on the DOUT line with a MSB-first sequence
followed by a LSB-first sequence. With the half-duplex
serial interface the DOUT data is from the current conver-
sion. This provides easy interface to MSB-first or LSB-first

serial ports. Bringing CS high resets the LTC1292/LTC1297
for the next data exchange and puts the LTC1297 into its
power shutdown mode.
