The LTC1093CN#PBF is a 10-bit Data Acquisition System designed to provide complete function, excellent accuracy and ease of use when digitizing analog data from a wide variety of signal sources and transducers. Built around a 10-bit switched capacitor, successive approximation A/D core, this device includes software configurable analog multiplexers and bipolar and uni-polar conversion modes as well as on-chip sample-and-holds. On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers. This circuit can provides a complete data acquisition system in ratio-metric applications or can be used with an external reference in others. The high impedance analog inputs and the ability to operate with reduced spans allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.
