AD7661
14位， 1 MSPS ，差分可编程输入的PulSAR ADC 14-Bit, 1 MSPS, Differential, Programmable Input PulSAR ADC
Product Details
The is a 16-bit, 100kSPS, 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.
