AD7667ASTZ

AD7667 is a 16bit, charge redistribution SAR analogue-to-digital converter that operates from a single 5V power supply. The part contains a high speed 16bit sampling ADC, an internal conversion clock, internal reference, error correction circuits, and both serial and parallel system inter- face ports. It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous applications, and a reduced power mode (Impulse) for low power applications where power is scaled with the throughput. The AD7667 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. Typical applications include data acquisition, medical instruments, digital signal processing, battery-powered systems, process control.
