It uses LTCMOSTM switched capacitor technology to perform a 12-bit unipolar A/D conversion. The input multiplexer can be configured for either single-ended or differential inputs. An on-chip sample-and-hold is included on the “+” input. When All these features are packaged in an 8-pin DIP. Given the accuracy, ease of use and small package size, this device is well suited for digitizing analog signals in remote applications where minimum number of interconnects, small physical size, and low power consumption are important. , LTC and LT are registered trademarks of Linear Technology Corporation.
