Product Summary
The LTC1277CSW#TR is an 8ms sampling 12-bit A/D converter which draws only 2mA (typ) from single 5V or ±5V supplies. These easy-to-use devices come complete with a 2ms sample-and-hold, a precision reference and an internally trimmed clock. Unipolar and bipolar conversion modes add to the flexibility of the ADCs. The applications of the LTC1277CSW#TR include Battery-Powered Portable Systems, High Speed Data Acquisition for PCs, Digital Signal Processing, Multiplexed Data Acquisition Systems, Audio and Telecom Processing, Spectrum Analysis.
