AD7666ASTZ
ANALOG DEVICES AD7666ASTZ 模数转换器, 16 bit, 500 kSPS, 单, 4.75 V, 5.25 V, LQFP
Product Details
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.
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.
