It contains a high-speed 16-bit sampling ADC, a resistor input scaler which allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.

The AD7665 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.
