No missing codes is • Offset Correction specified over the full operating temperature range. • Selectable Offset Binary or 2's Complement The unique two stage architecture achieves 9.4 Output Effective Bits over the entire Nyquist band at 40 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 +3.0V 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- • 3V TTL Logic Input/Output Compatible bit multiplexed or 20-bit parallel output mode. An offset correction feature minimizes the offset error. APPLICATIONS To ease interfacing to most low voltage systems, the • Digital Video digital output power pins of the ADC10D040 can be tied to a separate supply voltage of 1.5V to 3.6V, • CCD Imaging making the outputs compatible with other low voltage • Portable Instrumentation systems. When not converting, power consumption • Communications can be reduced by pulling the PD (Power Down) pin high, placing the converter into a low power state • Medical Imaging where it typically consumes less than 1 mW and from • Ultrasound which recovery is less than 1 ms. Bringing the STBY (Standby) pin high places the converter into a KEY SPECIFICATIONS standby mode where power consumption is about 30 mW and from which recovery is 800 ns. • Resolution: 10 Bits • Conversion Rate: 40 MSPS The ADC10D040's speed, resolution and single supply operation make it well suited for a variety of • ENOB: 9.4 Bits (typ) applications, including high speed portable • DNL: 0.35 LSB (typ) applications. • Conversion Latency Parallel Outputs: 2.5 Operating over the industrial ( −40° ≤ TA ≤ +85°C) Clock Cycles temperature range, the ADC10D040 is available in a – Multiplexed Outputs, I Data Bus: 2.5 Clock 48-pin TQFP. An evaluation board is available to Cycles ease the design effort. – Multiplexed Outputs, Q Data Bus: 3 Clock Cycles • PSRR: 90 dB • Power Consumption—Normal Operation: 267 mW (typ) – Power Down Mode: < 1 mW (typ) – Fast Recovery Standby Mode: 30 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.
