Linear Technology LTC1090
The LTC1090 is specified with offset and linearity less than ± 0.5LSB but with a gain error limit of ± 2LSB for applications where gain is adjustable or less critical.FEATURES

FEATURES
: Unipolar/Bipolar Conversions 4 Differential/8 Single Ended Inputs MSB or LSB First Data Sequence Variable Data Word Length Built-In Sample and Hold Single Supply 5V, 10V or ±5V Operation Direct 4 Wire Interface to Most MPU Serial Ports and All MPU Parallel Ports 30kHz Maximum Throughput Rate The LTC®1090 is a data acquisition component which contains a serial I/O successive approximation A/D converter. It uses LTCMOSTM 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 complement output coding in the bipolar mode.
