AD7653 16-Bit 1 MSPS PulSAR® Unipolar ADC with Ref
The AD7653 is a 16-bit, 1 MSPS, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. The part contains a high-speed, 16-bit 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) 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 and a tiny 48-lead LFCSP with operation specified from -40°C to +85°C.
