The AD7641 is a 18-bit, 2 MSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 2.5 V power supply. The part contains a high-speed 18-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system interface ports. It features a very high sampling rate mode (Warp) and a fast mode (Normal) for asynchronous conversion rate applications.

The AD7641 is hardware factory calibrated and comprehensively tested to ensure ac parameters such as signal-to-noise ratio (SNR) and total harmonic distortion (THD) in addition to the more traditional dc parameters of gain, offset and linearity.

Operation is specified from −40°C to +85°C.

PRODUCT HIGHLIGHTS

  1. Fast Throughput.
    The AD7641 is a 2 MSPS, charge redistribution, 18-bit SAR ADC.
  2. Superior Linearity.
    The AD7641 has no missing 18-bit code.
  3. Internal Reference.
    The AD7641 has a 2.048 V internal reference with a typical drift of ±10 ppm/°C and an on-chip TEMP sensor.
  4. Single-Supply Operation.
    The AD7641 operates from a 2.5 V single supply.
  5. Serial or Parallel Interface.
    Versatile parallel (16- or 8-bit bus) or 2-wire serial interface arrangement compatible with 2.5 V, 3.3 V, or 5 V logic.
