Linear Technology LTC1293
The LTC1293/4/6 is a family of data acquisition systems which contain a serial I/O successive approximation A/D converter. It uses LTCMOSTM switched capacitor technology to perform either 12-bit unipolar, or 11-bit plus sign bipolar A/D conversions. The input multiplexer can be configured for either single ended or differential inputs (or combinations thereof).| Part No. | LTC1293 |

FEATURES
● Software ProgrammableFEATURES
Unipolar/Bipolar Conversion Differential/Single Ended Inputs MSB-First or MSB/LSB Data Sequence Power Shutdown● Built-In Sample and Hold
● Single Supply 5V or ±5V Operation
● Direct 4-Wire Interface to Most MPU Serial Ports and All MPU Parallel Ports
● 46.5kHz Maximum Throughput Rate
● System Shutdown Output (LTC1296) KEY SPECIFICATIO S
● Resolution: 12 Bits
● Fast Conversion Time: 12µs Max Over Temp
● Low Supply Current: 6.0mA DESCRIPTIO An on-chip sample and hold is included for all single ended input channels. When the LTC1293/4/6 is idle it can be powered down in applications where low power consumption is desired. The LTC1296 includes a System Shutdown Output pin which can be used to power down external circuitry, such as signal conditioning circuitry prior to the input mux. 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.
