Description

The LTC1292/LTC1297 are data acquisition systems that contain a 12-bit, switched-capacitor successive approximation A/D, a differential input, sample-and-hold on the (+) input, and serial I/O. When the LTC1297 is idle between conversions it automatically powers down reducing the supply current to 5mA, typically. The LTC1292 is capable of digitizing signals at a 60kHz rate and with the device's excellent AC characteristics, it can be used for DSP applications.All these features are packaged in an 8-pin DIP and are made possible using LTCMOSTM switched-capacitor technology.
The LTC1292/LTC1297 is designed to communicate without external hardware to most MPU serial ports and all MPU parallel I/O ports allowing data to be transmitted over three wires.Because of their accuracy, ease of use and small package size these devices are well suited for digitizing analog signals in remote applications where minimum number of interconnects and power consumption are important
