The Analog Devices AD7656BSTZ-REEL is a 16-bit, 250 ksps, 6 channel, analog-to-digital converter that features a SPI, a parallel, and a DSP interface. This device operates at a 5V power supply, and is packaged in a LQFP-64_10x10x05P package that is RoHS compliant. It offers an SNR of 73.5dB with a 0.65Hz bandwidth, and a THD of -110dB. The AD7656BSTZ-REEL supports a wide input range of ± 2V to ± 5V. It offers excellent common mode rejection performance for signals with odd harmonics, making it well suited for the acquisition and processing of low frequency signals. The AD7656BSTZ-REEL also features power-on reset circuitry, which significantly simplifies system-level circuit design. Additionally, the AD7656BSTZ-REEL has one two- wire serial interface and one four-wire SPI interface allowing flexible system architecture design and multicom operations.
