No missing codes is • Offset Correction ensured over the full operating temperature range. • Selectable Offset Binary or 2's Complement The unique two stage architecture achieves 9.5 Output Effective Bits over the entire Nyquist band at 20 MHz • Multiplexed or Parallel Output Bus sample rate. An output formatting choice of offset binary or 2's complement coding and a choice of two • Single +2.7V to 3.6V Operation gain settings eases the interface to many systems. • Power Down and Standby Modes Also allowing great flexibility of use is a selectable 10- bit multiplexed or 20-bit parallel output mode. An APPLICATIONS offset correction feature minimizes the offset error. • Digital Video To ease interfacing to most low voltage systems, the • CCD Imaging digital output power pins of the ADC10D020 can be tied to a separate supply voltage of 1.5V to 3.6V, • Portable Instrumentation making the outputs compatible with other low voltage • Communications systems. When not converting, power consumption • Medical Imaging can be reduced by pulling the PD (Power Down) pin high, placing the converter into a low power state • Ultrasound where it typically consumes less than 1 mW and from which recovery is less than 1 ms. Bringing the STBY KEY SPECIFICATIONS (Standby) pin high places the converter into a • Resolution 10 Bits standby mode where power consumption is about 27 mW and from which recovery is 800 ns. • Conversion Rate 20 MSPS • ENOB 9.5 Bits (typ) The ADC10D020's speed, resolution and single supply operation makes it well suited for a variety of • DNL 0.35 LSB (typ) applications, including high speed portable • Conversion Latency Parallel Outputs 2.5 Clock applications. Cycles Operating over the industrial ( −40° ≤ TA ≤ +85°C) • Multiplexed Outputs, I Data Bus 2.5 Clock temperature range, the ADC10D020 is available in a Cycles 48-pin TQFP package. An evaluation board is • Multiplexed Outputs, Q Data Bus 3 Clock available to ease the design effort. Cycles • PSRR 90 dB • Power Consumption—Normal Operation 150 mW (typ) • Power Down Mode <1 mW (typ) • Fast Recovery Standby Mode 27 mW (typ) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
