AD7665 is a 16-Bit, 570 kSPS CMOS ADC produced by Analog Devices. It has 500 kSPS (Normal Mode), 570 kSPS (Warp Mode) throughput, 16-Bit Resolution with No Missing Codes, -100 dB Typ @ 180 kHz THD, 64 mW Typical 15 �W @ 100 SPS Power-Down Mode: 7 �W Max Package: 48-Lead Qua features.
The AD7665 is a 16‑bit, charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers high‑speed sampling up to 570 kSPS in Warp mode and provides both serial (SPI/QSPI/MICROWIRE) and parallel (8‑ or 16‑bit) interfaces.
Key features include a typical power dissipation of 64 mW, an INL of ±2.5 LSB with no missing codes, and selectable input voltage ranges (bipolar ±10 V, ±5 V, ±25 V or unipolar 0‑10 V, 0‑5 V, 0‑25 V). The device is available in 48‑lead LQFP and LFCSP packages and is calibrated at the factory for high accuracy.
