The AD7664AST is a 16-bit successive approximation register (SAR) analog-to-digital converter from Analog Devices. It offers a maximum sampling rate of 570 kSPS in warp mode and supports normal and impulse operating modes. The device accepts a unipolar analog input voltage range of 0 V to 2.5 V and operates from a single 5 V supply, with a maximum power dissipation of 115 mW.
Key electrical characteristics include an integral nonlinearity (INL) of 2.5 LSB maximum, a signal-to-noise and distortion ratio (SINAD) of 90 dB typical at 45 kHz, and total harmonic distortion (THD) of -100 dB typical at 45 kHz. The ADC uses a charge redistribution SAR architecture and provides no pipeline delay, making it suitable for precise data acquisition.
The AD7664AST is available in a 48-lead LQFP package (7x7 mm) for surface mount assembly. It offers flexible digital interfaces including parallel, serial, and SPI, compatible with 5V and 3V logic levels. The device is designed for applications such as data acquisition, instrumentation, digital signal processing, spectrum analysis, medical instruments, battery-powered systems, and process control.
