The LTC1283 is a 3V data acquisition component which
contains a serial I/O successive approximation A/D con-
verter. It uses LTCMOS
TM switched capacitor technology
to perform either 10-bit unipolar, or 9-bit plus sign bipolar
A/D conversions. The 8-channel input multiplexer can be
configured for either single-ended or differential inputs (or
combinations thereof). An on-chip sample-and-hold is
included for all single-ended input channels.
The serial I/O is designed to be compatible with industry-
standard full-duplex serial interfaces. It allows either MSB-
or LSB-first data and automatically provides 2’s comple-
ment output coding in the bipolar mode. The output data
word can be programmed for a length of 8-, 10-, 12-, or
16-bit. This allows easy interface to shift registers and a
variety of processors.
Both the LTC1283A and LTC1283 are specified with offset
and linearity errors less than
±0.5LSB. The LTC1283A has
a gain error limit of
±1LSB. The 1283 is specified with a
gain error limit of
±2LSB for applications where gain is
adjustable or less critcial.
