It provides 125 kSPS throughput with 8 single-ended analog inputs (AIN1-AIN8) and an analog input range of 0 to VREF. The on-chip 2.5V reference can also be overridden with an external reference (1.2V to VDD). The device consumes only 2 mW in normal operation and 3 \u00b5W in power-down mode, with a SPI\/QSPI\/MICROWIRE\/DSP compatible serial interface.","working_principle":"The AD7888 operates through four subsystems: (1) Input Multiplexer: An 8-channel analog multiplexer selects one of eight single-ended inputs under control of the serial interface. (2) Sample-and-Hold: Acquires the selected input signal in 500 ns, holding it stable during conversion. (3) SAR ADC Core: A 12-bit successive approximation register converter performs the A\/D conversion in 14.5 SCLK cycles (7.25\u00b5s at 2MHz clock), using a charge redistribution DAC architecture. (4) Reference and Control: An on-chip 2.5V bandgap reference provides the conversion reference, with the option to apply an external reference. Power management allows automatic power-down after conversion.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>CS<\/td><td>Input<\/td><td>Chip select (active low)<\/td><\/tr><tr><td>2<\/td><td>REFIN\/REFOUT<\/td><td>I\/O<\/td><td>Reference input\/output<\/td><\/tr><tr><td>3<\/td><td>AIN1<\/td><td>Analog Input<\/td><td>Analog input channel 1<\/td><\/tr><tr><td>4<\/td><td>AIN2<\/td><td>Analog Input<\/td><td>Analog input channel 2<\/td><\/tr><tr><td>5<\/td><td>AIN3<\/td><td>Analog Input<\/td><td>Analog input channel 3<\/td><\/tr><tr><td>6<\/td><td>AIN4<\/td><td>Analog Input<\/td><td>Analog input channel 4<\/td><\/tr><tr><td>7<\/td><td>AIN5<\/td><td>Analog Input<\/td><td>Analog input channel 5<\/td><\/tr><tr><td>8<\/td><td>AIN6<\/td><td>Analog Input<\/td><td>Analog input channel 6<\/td><\/tr><tr><td>9<\/td><td>GND<\/td><td>Ground<\/td><td>Ground<\/td><\/tr><tr><td>10<\/td><td>AIN7<\/td><td>Analog Input<\/td><td>Analog input channel 7<\/td><\/tr><tr><td>11<\/td><td>AIN8<\/td><td>Analog Input<\/td><td>Analog input channel 8<\/td><\/tr><tr><td>12<\/td><td>DIN<\/td><td>Input<\/td><td>Serial data input (control bits)<\/td><\/tr><tr><td>13<\/td><td>DOUT<\/td><td>Output<\/td><td>Serial data output (conversion result)<\/td><\/tr><tr><td>14<\/td><td>SCLK<\/td><td>Input<\/td><td>Serial clock input<\/td><\/tr><tr><td>15<\/td><td>VDD<\/td><td>Power<\/td><td>Supply voltage (2.7V to 5.25V)<\/td><\/tr><tr><td>16<\/td><td>AGND<\/td><td>Ground<\/td><td>Analog ground<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Multi-channel data acquisition in battery-powered medical instruments<\/li><li>Industrial process monitoring with 8-channel sensor arrays<\/li><li>Portable data logging systems requiring low power consumption<\/li><li>Mobile communication baseband signal digitization<\/li><li>High-speed modem analog front-end<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Resolution<\/th><th>Rate<\/th><th>Notes<\/th><\/tr><tr><td>AD7888ARUZ-REEL7<\/td><td>ADI<\/td><td>12-bit<\/td><td>125kSPS<\/td><td>TSSOP-16 package<\/td><\/tr><tr><td>AD7091R-8<\/td><td>ADI<\/td><td>12-bit<\/td><td>1MSPS<\/td><td>Higher speed option<\/td><\/tr><tr><td>MCP3208-CI\/SL<\/td><td>Microchip<\/td><td>12-bit<\/td><td>100kSPS<\/td><td>Lower cost alternative<\/td><\/tr><tr><td>ADS7042<\/td><td>TI<\/td><td>12-bit<\/td><td>1MSPS<\/td><td>Single-channel high-speed<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3407","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=3407"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3407\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=3407"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=3407"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=3407"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=3407"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
