GENERAL DESCRIPTION
The AD7674 is an 18-bit, 800 kSPS, charge redistribution SAR,
fully differential analog-to-digital converter that operates on a
single 5 V power supply. The part contains a high speed 18-bit
sampling ADC, an internal conversion clock, an internal
reference buffer, error correction circuits, and both serial and
parallel system interface ports.
The part is available in 48-lead LQFP or 48-lead LFCSP
packages with operation specified from –40°C to +85°C.
