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 AD7664 is hardware factory calibrated and is prehensively 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) and, for asynchronous conversion rate applications, a fast mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput. It is fabricated using Analog Devices’ high-performance, 0.6 micron CMOS process, with correspondingly low cost and is available in a 48-lead LQFP with operation specified from - 40°C to +85°C. - Patent pending. 1.
