Product Summary

The LTC1420CGN is a 10Msps, 12-bit sampling A/D converter that draws only 250mW from either single 5V or dual ±5V supplies. This easy-to-use device includes a high dynamic range sample-and-hold, a precision reference and a PGA input circuit. The LTC1420CGN has a flexible input circuit that allows fullscale input ranges of ±2.048V ±1.024V and ±0.512V. The input common mode voltage is arbitrary, though a 2.5V reference is provided for single supply applications. The applications of the LTC1420CGN include: Telecommunications, Digital Signal Processing, Multiplexed Data Acquisition Systems, High Speed Data Acquisition, Spectral Analysis, Imaging Systems.
