AD7625BCPZ

AD7625 is a 16bit, 6MSPS, charge redistribution successive approximation register (SAR) based architecture analogue-to-digital converter (ADC). SAR architecture allows unmatched performance both in noise and in linearity. The AD7625 contains a high speed, 16bit sampling ADC, an internal conversion clock and an internal buffered reference. On the CNV± rising edge, it samples the voltage difference between the IN+ and IN- pins. The voltages on these pins swing in opposite phase between 0V and REF. The 4.096V reference voltage, REF, can be generated internally or applied externally. All converted results are available on a single LVDS self-clocked or echoed-clock serial interface, reducing external hardware connections. Typical applications include high dynamic range telecommunications, receivers, digital imaging systems, high speed data acquisition, spectrum analysis and test equipment.
