Product Details

The AD7677 is a 16-bit, 1 MSPS, charge redistribution SAR, fully differential, analog-to-digital converter that operates from a single 5 V power supply. The part contains a high speed 16-bit sampling ADC, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.

The AD7677 is hardware factory calibrated and comprehensively tested to ensure such ac parameters as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity.

It features a very high sampling rate mode (Warp); a fast mode (Normal) for asynchronous conversion rate applications; and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput.

The AD7677 is available in a 48-lead LQFP or a tiny 48-lead LFCSP with operation specified from –40°C to +85°C.


  1. Excellent INL
    The AD7677 has a maximum integral nonlinearity of 1 LSB with a no missing 16-bit code.
  2. Superior AC Performances
    The AD7677 has a minimum dynamic of 92 dB, 94 dB typical.
  3. Fast Throughput
    The AD7677 is a 1 MSPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry.
  4. Single-Supply Operation
    The AD7677 operates from a single 5 V supply and typically dissipates only 115 mW. Its power dissipation decreases with the throughput. It consumes 7 µW maximum when in power-down.
  5. Serial or Parallel Interface
    Versatile parallel (8 bits or 16 bits) or 2-wire serial interface arrangement compatible with both 3 V or 5 V logic.
