Product Details

The AD7676 is a 16-bit, 500 kSPS, charge redistribution SAR, fully differential analog-to-digital converter (ADC) 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 AD7676 is hardware factory-calibrated and is 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 is fabricated using Analog Devices’ high performance, 0.6 micron CMOS process and is available in a 48-lead LQFP or a tiny 48-lead LFCSP with operation specified from –40°C to +85°C.

  • Medical Instruments
  • Battery-Powered Systems
  • Process Control

PRODUCT HIGHLIGHTS

  1. Excellent INL
    The AD7676 has a maximum integral nonlinearity of 1.0 LSB with no missing 16-bit code.
  2. Superior AC Performances
    The AD7676 has a minimum dynamic of 92 dB, 94 dB typical.
  3. Fast Throughput
    The AD7676 is a 500 kSPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry.
  4. Single-Supply Operation
    The AD7676 operates from a single 5 V supply and typically dissipates only 67 mW. 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 either 3 V or 5 V logic.
