AD7609BSTZ

The AD7609BSTZ is a fully integrated data acquisition system from Analog Devices featuring eight simultaneously sampled differential input channels. It provides 18-bit resolution with a sampling rate of 200 kSPS per channel and a typical signal-to-noise ratio of 101 dB. The device accepts true bipolar analog input ranges of ±20 V and ±10 V, accommodating a wide variety of sensor and signal sources. It operates from a single 5 V analog supply and a 2.3 V to 5.25 V VDRIVE supply, making it compatible with multiple logic levels. The ADC includes an on-chip reference, input clamp protection, and a second-order antialiasing filter to simplify system design. The interface is SPI/QSPI/MICROWIRE compatible, allowing easy integration with microcontrollers and DSPs. Power dissipation is typically 100 mW, with a standby mode reducing consumption to 25 mW. The device is packaged in a 64-lead LQFP and operates over the industrial temperature range of -40°C to +85°C. Typical applications include power line monitoring, multiphase motor control, instrumentation, and multiaxis positioning systems. The AD7609BSTZ is RoHS compliant and lead-free, suitable for environmental compliance requirements.
