AD7664 is a 16-Bit, 570 kSPS PulSAR ® Unipolar CMOS ADC from Analog Devices.
The AD7664 is a 16‑bit, 570 kSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers parallel and serial (SPI/QSPI/MICROWIRE/DSP) interfaces, selectable throughput modes (Warp, Normal, Impulse), and low power consumption.
The device is supplied in 48‑lead LQFP and 48‑lead LFCSP packages, supports an input range of 0 V to 2.5 V, and provides high accuracy with an INL of up to 2.5 LSB, SNR of 90 dB typ, and THD of –100 dB typ. Detailed pin configurations, timing specifications, and absolute maximum ratings are included.
