Circuit Applications of Sample-Hold Amplifiers
Most designers are familiar with the sample-hold amplifier as a system component which is utilized in high speed data acquisition work. In these applications, the sample-hold amplifier is used to store analog data which is then digitized by a relatively slow A/D converter. In this fashion, high speed or multiplexed analog data can be digitized without resorting to complex and expensive ultra-high speed A/D converters. The use of sample-hold amplifiers as circuit oriented components is not as common as the class of application described above. This is unfortunate, because sampling techniques allow circuit functions which are sophisticated, low cost and not easily achieved with other approaches. An……
