The ADC10D040 is a dual low power, high performance CMOS analog-to-digital converter that digitizes signals to 10 bits resolution at sampling rates up to 45 MSPS while consuming a typical 267 mW from a single 3.3V supply. No missing codes is guaranteed over the full operating temperature range. The unique two stage architecture achieves 9.4 Effective Bits over the entire Nyquist band at 40 MHz sample rate. An output formatting choice of offset binary or 2’s complement coding and a choice of two gain settings eases the interface to many systems. Also allowing great flexibility of use is a selectable 10-bit multiplexed or 20-bit parallel output mode. An offset correction feature minimizes the offset error.
