HMCAD1511

HMCAD1511 is a versatile high performance low power analogue-to-digital converter (ADC), utilizing time-interleaving to increase sampling rate. Integrated cross point switches activate the input selected by the user. In single channel mode, one of the four inputs can be selected as a valid input to the single ADC channel. In dual channel mode, any two of the four inputs can be selected to each ADC channel. In quad channel mode, any input can be assigned to any ADC channel. HMCAD1511 is pin compatible with HMCAD1520, HMCAD1511 is pin compatible and can be configured to operate as HMCAD1510. Typical applications include USB powered oscilloscopes, digital oscilloscopes and satellite receivers.
