APPLICATION INFORMATION
THEORY OF OPERATION
The ADS5510 is a low-power, 11-bit, 125 MSPS, CMOS, switched capacitor, pipeline ADC that operates from a
single 3.3-V supply. The conversion process is initiated by a falling edge of the external input clock. Once the
signal is captured by the input S&H, the input sample is sequentially converted by a series of small resolution
stages, with the outputs combined in a digital correction logic block. Both the rising and the falling clock edges
are used to propagate the sample through the pipeline every half clock cycle. This process results in a data
latency of 17.5 clock cycles, after which the output data is available as a 11-bit parallel word, coded in either
straight offset binary or binary two's complement format.
INPUT CONFIGURATION
The analog input for the ADS5510 consists of a differential sample-and-hold architecture implemented using the
switched capacitor technique shown in
