AD7652 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. APPLICATIONS Data acquisition Instrumentation Digital signal processing Spectrum analysis Medical instruments Battery-powered systems Process control

The AD7652 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.
