LTC1093 - 1, 2, 6 and 8 Channel, 10-Bit Serial I/O Data Acquisition Systems - Linear Technology（凌力尔特）

The H (Metal Can), J (Ceramic), and K (Metal Can) Packages From Linear Technology Are Now Obsolete

The high impedance analog inputs and the ability to operate with reduced spans (below 1V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages. An efficient serial port communicates without external hardware to most MPU serial ports and all MPU parallel I/O ports allowing eight channels of data to be transmitted over as few as three wires. This, coupled with low power consumption, makes remote location possible and facilitates transmitting data through isolation barriers. Temperature drift of offset, linearity and full-scale error are all extremely low (1ppm/°C typically) allowing all grades to be specified with offset and linearity errors of ±0.5LSB maximum over temperature. In addition, the A grade devices are specified with full-scale error and total unadjusted error (including the effects of offset, linearity and full-scale errors) of ±1LSB maximum over temperature. The lower grade has a full-scale specification of ±2LSB for applications where full scale is adjustable or less critical.
