AD7653ASTZ

AD7653 is a 16-bit, 1MSPS, charge redistribution SAR analogue-to-digital converter. The part contains a high speed 16-bit sampling ADC, internal conversion clock, internal reference, error correction circuits and both serial and parallel system interface ports. It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous conversion rate applications and a reduced power mode (Impulse) for low power applications where power is scaled with the throughput. The AD7653 is fabricated using Analog Devices’ high performance, 0.6micron CMOS process with correspondingly low cost. Typical applications include data acquisition, instrumentation, digital signal processing, spectrum analysis, medical instruments, battery-powered systems and process control.
