Overview
The LTC1863/LTC1867 are complete, low power multi-
plexed ADCs. They consist of a 12-/16-bit, 200ksps capaci-
tive successive approximation A/D converter, a precision
internal reference, a congurable 8-channel analog input
multiplexer (MUX) and a serial port for data transfer.
Conversions are started by a rising edge on the CS/CONV
input. Once a conversion cycle has begun, it cannot be
restarted. Between conversions, the ADCs receive an input
word for channel selection and output the conversion
result, and the analog input is acquired in preparation for
the next conversion. In the acquire phase, a minimum time
of 1.5μs will provide enough time for the sample-and-hold
capacitors to acquire the analog signal.
During the conversion, the internal differential 16-bit
capacitive DAC output is sequenced by the SAR from
the most signicant bit (MSB) to the least signicant bit
(LSB). The input is sucessively compared with the binary
weighted charges supplied by the differential capacitive
DAC. Bit decisions are made by a low-power, differential
comparator. At the end of a conversion, the DAC output
balances the analog input. The SAR contents (a 12-/16-bit
data word) that represent the analog input are loaded into
the 12-/16-bit output latches.
