HMCAD1520

HMCAD1520 is a versatile high performance low power analogue-to-digital converter (ADC), with interleaving high speed modes 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 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 and precision mode, any input can be assigned to any ADC channel. Typical applications includes precision oscilloscopes, spectrum analysers, diversity receivers, Hi-end ultrasound, communication testing and non destructive testing.

• High speed modes (12bit/8bit) quad channel mode: FSmax = 160/250MSPS
