The ADC12DS105 is a high-performance CMOS analog-to-digital converter capable of converting two analog input signals into 12-bit digital words at rates up to 105 Mega Samples Per Second (MSPS). The digital outputs are serialized and provided on differential LVDS signal pairs. This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component count, while providing excellent dynamic performance. The ADC12DS105 may be operated from a single +3.0V or 3.3V power supply. A power-down feature reduces the power consumption to very low levels while still allowing fast wake-up time to full operation. The differential inputs accept a 2V full scale differential input swing. A stable 1.2V internal voltage reference is provided, or the ADC12DS105 can be operated with an external 1.2V reference. The selectable duty cycle stabilizer maintains performance over a wide range of clock duty cycles. A serial interface allows access to the internal registers for full control of the ADC12DS105's functionality. The ADC12DS105 is available in a 60-lead WQFN package and operates over the industrial temperature range of ?40°C to +85°C
