Product Summary
The LTC1294DCSW#TR is a Single Chip 12-Bit Data Acquisition System. It uses LTCMOSTM switched capacitor technology to perform either 12-bit unipolar, or 11-bit plus sign bipolar A/D conversions. When the LTC1294DCSW#TR is idle it can be powered down in applications where low power consumption is desired. The serial I/O is designed to communicate without external hardware to most MPU serial ports and all MPU parallel I/O ports allowing up to eight channels of data to be transmitted over as few as three wires. The LTC1294DCSW#TR contains a serial I/O successive approximation A/D converter.
