The device provides six differential analog input channels accessed through an input multiplexer, supporting multi-sensor measurement systems. The programmable gain amplifier (PGA) offers gains from 1 to 128, enabling direct measurement of small sensor signals such as thermocouples, strain gauges, and RTDs without external signal conditioning. At the lowest output data rate of 4.17 Hz, the AD7795 achieves an RMS noise of only 40 nV, corresponding to an effective resolution of 23 bits. The on-chip bandgap reference has a typical drift of 4 ppm\/\u00b0C, ensuring measurement stability over temperature. Simultaneous 50 Hz and 60 Hz notch filters reject power-line interference, critical in industrial environments.","working_principle":"The AD7795BRUZ operates through five integrated subsystems: (1) The input multiplexer selects one of six differential input channel pairs for conversion, routing the selected signal to the PGA input. An additional bias voltage generator can set the common-mode voltage of a channel to AVDD\/2, useful for single-supply sensor biasing. (2) The programmable gain instrumentation amplifier provides gains from 1 to 128 in binary steps, amplifying small sensor signals to utilize the full ADC dynamic range. The PGA is chopper-stabilized for low offset drift. (3) The 16-bit sigma-delta modulator oversamples the input signal at a high frequency, producing a 1-bit data stream. The decimation filter then processes this stream to produce the final output word at the programmed data rate (4.17 Hz to 470 Hz). At lower data rates, more decimation provides lower noise and higher effective resolution. (4) The on-chip reference provides a stable 1.17 V reference with 4 ppm\/\u00b0C typical drift. Alternatively, up to two external differential references can be connected. (5) The excitation current sources can be programmed to output precise currents for biasing resistive sensors such as RTDs, while the power-down switch can disconnect bridge sensors between conversions to save power.","pin_description":"<table><tr><td>Pin No.<\/td><td>Pin Name<\/td><td>Function<\/td><\/tr><tr><td>1<\/td><td>SCLK<\/td><td>Serial clock input for SPI interface<\/td><\/tr><tr><td>2<\/td><td>CS<\/td><td>Chip select input (active low)<\/td><\/tr><tr><td>3<\/td><td>RDY<\/td><td>Ready output; goes low when conversion is complete<\/td><\/tr><tr><td>4<\/td><td>DIN<\/td><td>Serial data input for writing to registers<\/td><\/tr><tr><td>5<\/td><td>DOUT\/RDY<\/td><td>Serial data output \/ alternate ready output<\/td><\/tr><tr><td>6-7<\/td><td>AIN1-AIN6<\/td><td>Differential analog input pairs (6 channels)<\/td><\/tr><tr><td>8-10<\/td><td>REF+\/REF-<\/td><td>External reference inputs<\/td><\/tr><tr><td>11<\/td><td>IOUT1\/IOUT2<\/td><td>Programmable excitation current outputs<\/td><\/tr><tr><td>12<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>13<\/td><td>AVDD<\/td><td>Analog supply voltage (2.7-5.25 V)<\/td><\/tr><tr><td>14<\/td><td>DVDD<\/td><td>Digital supply voltage (2.7-5.25 V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Precision weigh scale systems where 23-bit effective resolution and 40 nV RMS noise enable sub-microvolt measurement accuracy with strain gauge load cells<\/li><li>Temperature measurement using RTDs with programmable excitation current sources and PGA gain up to 128 for direct small-signal measurement without external amplification<\/li><li>Industrial pressure transmitter front-ends requiring low-power 400 uA operation with simultaneous 50\/60 Hz rejection for power-line noise immunity<\/li><li>Gas analysis instrumentation where the multi-channel differential input mux and on-chip reference simplify multi-sensor system design<\/li><\/ul>","alternative_models":"<table><tr><td>Model<\/td><td>Brand<\/td><td>Resolution<\/td><td>Channels<\/td><td>PGA<\/td><\/tr><tr><td>AD7794BRUZ<\/td><td>ADI<\/td><td>24-bit<\/td><td>6<\/td><td>1-128<\/td><\/tr><tr><td>AD7192BRUZ<\/td><td>ADI<\/td><td>24-bit<\/td><td>8<\/td><td>1-128<\/td><\/tr><tr><td>ADS1232IPWR<\/td><td>TI<\/td><td>24-bit<\/td><td>2<\/td><td>1-128<\/td><\/tr><tr><td>MCP3464T-E\/ST<\/td><td>Microchip<\/td><td>24-bit<\/td><td>4<\/td><td>1-64<\/td><\/tr><tr><td>CY8CKIT-044<\/td><td>Infineon<\/td><td>20-bit<\/td><td>4<\/td><td>1-8<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3212","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=3212"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3212\/revisions"}],"predecessor-version":[{"id":3293,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3212\/revisions\/3293"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=3212"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=3212"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=3212"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=3212"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
