AD7667ACPZ
ADC Single SAR 1MSPS 16Bit Parallel/Serial 48Pin LFCSP EP
Product Details
The AD7667 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 interface 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. .
