Overview
The AD7667ACP is a 16-bit, 1 MSPS (Mega Samples Per Second) PulSAR (Successive Approximation Register) unipolar analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC operates from a single 5 V power supply and is designed for high-speed and low-power applications. It features internal conversion clock, internal reference, error correction circuits, and both serial and parallel system interface ports. The AD7667ACP is housed in either a 48-lead LQFP (Low Profile Quad Flat Package) or a 48-lead LFCSP (Lead Frame Chip Scale Package), making it suitable for space-saving and flexible configurations.
