The device passes a flexible multiplexer input (MUX), low noise, programmable gain amplifier (PGA), two excitation current sources, a voltage reference, an oscillator, a low side switch and an accurate Temperature sensor for implement two differential or four single-ended inputs. <br />The device can be converted to a data rate of 2000 samples per second (SPS) with a single precipitation cycle. At 20 SPs, the digital filter provides simultaneous 50Hz and 60Hz rejection for industrial applications noise. <br />The internal PGA provides high gain at 128 V / V. The PGA makes the ADS1220 perfect for measuring small sensor signals such as resistance temperature detectors (RTDs), thermocouples, thermistors, and resistive bridge sensors. <br />The device supports the measurement of pseudo or fully differential signals when using the programmable gate array. Alternatively, the device can be configured to pass through the internal PGA while still providing high input impedance and gain of up to 4 VnV, allowing single-ended measurements. <br />In the duty cycle mode, when the PGA is disabled, the power consumption is as low as 120pa. The ADS1220 is available in a lead-free VQFN-16 or ATSSOP-16 package and is specified above the -40℃ to + 125℃ temperature range. <br /> <br />K type of measuring thermocouple <br />Low current consumption: starting at 120μA in duty cycle mode (typical) <br />Power range: 3V ~ 5V <br />Up to 20 effective resolutions <br />Two differential or four single-ended inputs <br />Dual matched programmable current source: 10μA to 1.5mA <br />Internal 2.048V Reference: 5ppm / &deg; C (typical) Drift <br />Internal 2% precision oscillator <br />Internal temperature sensor: 0.5 &deg; C (typical) precision <br />SPI compatible interface (mode 1) <br />Applications: <br />Measuring temperature sensor: <br />1.
