AD7666 16-Bit, 500 kSPS PulSAR® Unipolar ADC with Ref

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.

The AD7666 is a 16-bit, 500 kSPS, 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 interface ports.
