Overview
The AD7665ASTZ is a 16-bit, 570 kSPS (kilosamples per second), charge redistribution Successive Approximation Register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This high-speed ADC operates from a single 5 V power supply and is designed for various high-performance applications. It features a high-speed 16-bit sampling ADC, a resistor input scaler for various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports. The AD7665ASTZ is hardware factory-calibrated and comprehensively tested to ensure high accuracy and reliability in terms of signal-to-noise ratio (SNR), total harmonic distortion (THD), gain, offset, and linearity.
