Description
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.
