AD7689BCPZRL7, , аналого-цифровой преобразователь (АЦП) с быстродействием , 16-Бит, 8 каналов, 250 kSPS, корпус LFCSP-20
МИКРОСХЕМЫ\АЦП
AD7689 is a 8-channel, 16bit, charge redistribution successive approximation register (SAR) analogue to-digital converter (ADCs) that operate from a single power supply, VDD. The device uses a simple serial port interface (SPI) for writing to the configuration register and receiving conversion results. The SPI interface uses a separate supply, VIO, which is set to the host logic level. Power dissipation scales with throughput. It is widely used in application such as multichannel system monitoring, battery-powered equipment, medical instruments: ECG/EKG, mobile communications: GPS, power line monitoring, data acquisition, seismic data acquisition systems, instrumentation, process control etc.
