16位ADC通道500kSPS的脉冲星ad7699数据表

　　The AD7699 is an 8-channel， 16-bit， charge redistribution successive approximation register （SAR） analog-to-digital converter （ADC） that operates from a single power supply， VDD. The AD7699 contains all components for use in a multichannel， low power data acquisition system， including a true 16-bit SAR ADC with no missing codes; an 8-channel low crosstalk multiplexer useful for configuring the inputs as single-ended （with or without ground sense）， differential， or bipolar; an internal 4.096 V low drift reference and buffer; a temperature sensor; a selectable one-pole filter; and a sequencer that is useful when channels are continuously scanned in order. The AD7699 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. The AD7699 is housed in a tiny 20-lead LFCSP and a 20-ball WLCSP with operation specified from −40°C to +85°C.
