Low Cost, 16-Bit Accurate Sample-and-Hold Amplifier

The AD1154 is a high accuracy, low cost sample-and-hold amplifier (SHA) designed to be used in high resolution data acquisition systems. It is complete with internal hold capacitor and propriety capacitor trimmed compensation circuitry. Its accuracy (0.00076% of full scale range) and dynamic performance allow it to be used with high speed 16-bit A/D converters. The AD1154's low price enables users to upgrade the front end performance of 14-bit systems without increasing system cost. Its gain accuracy and droop rate in "hold" mode also allow accurate conversion by slower 16-bit A/D converters having conversion times of up to 7.6 ms.
