ANALOG DEVICES AD7949SCPZ-EP-RL7 模数转换器, 八路, 14 bit, 250 kSPS, 单, 2.3 V, 5.5 V, LFCSP
Product Details
The AD7949 is an 8-channel, 14-bit, charge redistribution successive approximation register SAR analog-to-digital converter ADC that operates from a single power supply, VDD.
The AD7949 contains all components for use in a multichannel, low power data acquisition system, including a true 14-bit SAR ADC with no missing codes; an 8-channel, low crosstalk multiplexer that is useful for configuring the inputs as single-ended with or without ground sense, differential, or bipolar; an internal low drift reference selectable 2.5 V or 4.096 V and buffer; a temperature sensor; a selectable one-pole filter; and a sequencer that is useful when channels are continuously scanned in order.
The AD7949 uses a simple SPI interface 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.
The AD7949 is housed in a tiny 20-lead LFCSP with operation specified from −40°C to +85°C.
