AD9229 THEORY OF OPERATION The AD9229 architecture consists of a front-end switched capa- citor sample-and-hold amplifier (SHA) followed by a pipelined ADC. The pipelined ADC is divided into three sections: a 4-bit first stage followed by eight 1.5-bit stages and ...

An internal reference buffer creates the positive and negative reference voltages, REFT and REFB, respectively, that defines the span of the ADC core. The output common-mode of the reference buffer is set to midsupply, and the REFT and REFB voltages ...

AD9229 High speed, high resolution ADCs are sensitive to the quality of the clock input. The degradation in SNR at a given full-scale input frequency (f ) due only to aperture jitter (t A calculated with the following equation: SNR ...
