    摘要： A successive approximation register analog-to-digital converter (SAR ADC) having a sample, hold and convert amplifier circuit may be configured for either a single channel SAR ADC or a multiple channel SAR ADC. Switches or metal connection options, e.g., bit configurable or metal mask configurable, respectively, may be used to configure a common capacitor area, a portion of which may be used as a reconfigurable charge-redistribution digital-to-analog converter (CDAC) of the SAR ADC as either a single channel sample, hold and convert 12-bit capacitor configuration or a four channel sample, hold and convert 10-bit capacitor configuration. All other parts of the SAR ADC circuitry may be substantially the same for either configuration, e.g., the resistive digital-to-analog converter (RDAC), successive approximation register (SAR), ADC controller, sample, hold and convert switches, comparator, etc, may be substantially the same for either the single or multiple channel SAR ADC configurations.

    摘要： An analog-to-digital converter (ADC) includes storage for one or more configuration parameter values. Configuration parameter values stored in the storage locations are used by control logic to configure the ADC's conversion mechanism. The configuration values may be arranged in lists that the control logic cycles through in order to modify the configuration of the ADC's conversion mechanism. The control logic may change from one list, or series of lists, to another in order to adapt the ADC to changing circumstances. The changing circumstances may include the changing state of charge in a battery monitoring application.

    摘要翻译： 模数转换器（ADC）包括用于一个或多个配置参数值的存储。 存储在存储位置的配置参数值由控制逻辑用于配置ADC的转换机制。 配置值可以排列在控制逻辑循环的列表中，以便修改ADC转换机制的配置。 控制逻辑可以从一个列表或一系列列表改变到另一个列表，以使ADC适应不断变化的环境。 不断变化的情况可能包括电池监控应用中的充电状态。
