The ADC10D020 is a dual low power, high performance CMOS analog-to-digital converter that
digitizes signals to 10 bits resolution at sampling rates up to 30 MSPS while consuming a typical
150 mW from a single 3.0V supply. No missing codes is ensured over the full operating temperature
range. The unique two stage architecture achieves 9.5 Effective Bits over the entire Nyquist band
at 20 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.
To ease interfacing to most low voltage systems, the digital output power pins of the
ADC10D020 can be tied to a separate supply voltage of 1.5V to 3.6V, making the outputs compatible
with other low voltage systems. When not converting, power consumption can be reduced by pulling
the PD (Power Down) pin high, placing the converter into a low power state where it typically
consumes less than 1 mW and from which recovery is less than 1 ms. Bringing the STBY (Standby) pin
high places the converter into a standby mode where power consumption is about 27 mW and from which
recovery is 800 ns.
The ADC10D020's speed, resolution and single supply operation makes it well suited for a
variety of applications, including high speed portable applications.
Operating over the industrial (−40° ≤ TA ≤ +85°C) temperature
range, the ADC10D020 is available in a 48-pin TQFP package. An evaluation board is available to
ease the design effort.
