描述The ADS8363 is a dual, 16-bit, 1-MSPS analog-to-digital converter (ADC) with eightpseudo- or four fully-differential input channels grouped into two pairs for simultaneous signalacquisition. The analog inputs are maintained differentially to the input of the ADC. The inputmultiplexer can be used in either pseudo-differential mode, supporting up to four channels per ADC(4x2), or in fully-differential mode that allows to convert up to two inputs per ADC (2x2). TheADS7263 is a 14-bit version and the ADS7223 is a 12-bit version of the ADS8363.The ADS8363, ADS7263, and ADS7223 offer two programmable reference outputs, flexiblesupply voltage ranges, a programmable auto-sequencer, data storage of up to four conversion resultsper channel, and several power-down features.All devices are offered in a 5-mm x 5-mm, 32-pin VQFN package.特性Eight Pseudo- or Four Fully-Differential Inputs Simultaneous Sampling of Two Channels Excellent AC Performance:SNR: 93 dB (ADS8363)85 dB (ADS7263)73 dB (ADS7223)THD:–98 dB (ADS8363)–92 dB (ADS7263)–86 dB (ADS7223) Dual Programmable and Buffered 2.5-V Reference Allows:TwoDifferent Input Voltage Range SettingsTwo-Level PGAImplementation Programmable Auto-Sequencer Integrated Data Storage (up to 4 per channel) for OversamplingApplications 2-Bit Counter for Safety Applications Fully Specified Over the Extended Industrial Temperature Range: –40°C to+125°CAll trademarks are the property of their respective owners.
