Product description:The DS1220 is a precision 24-bit analog-to-digital converter (ADC) that provides many integrated features to reduce system cost and component count for small sensor signals. The device passes a flexible input multiplexer (MUX), low noise, programmable gain amplifier (PGA), two programmable excitation current sources, a voltage reference, an oscillator, a low side switch and a precision Temperature sensor to implement two differential or four single-ended inputs.The device can be converted at a data rate of 2000 samples per second (SPS) with a single cycle of precipitation. At 20 SPs, the digital filter provides simultaneous 50 Hz and 60 Hz rejection for noise industrial applications. The internal PGA provides high gain to 128 V/V. The PGA makes the ADS1220 ideal for measuring small sensor signals such as resistance temperature detectors (RTDs), thermocouples, thermistors, and resistive bridge sensors. The device supports 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.In the duty cycle mode, when the PGA is disabled, the power consumption is as low as 120pa. The ADS1220 is available in a leadless VQFN-16 or ATSSOP-16 package and is specified over the -40C to +125C temperature range.K type thermocouple measurement Product Features:Low current consumption: as low as 120μA in duty cycle mode (typical)Power range: 3 V~5 VUp to 20 effective resolutionsTwo differential or four single-ended inputsDual matched programmable current source: 10μA to 1.5 mAInternal 2.048-V Reference: 5 ppm/°C (typical) DriftInternal 2% precision oscillatorInternal temperature sensor: 0.5°C (typical) accuracySPI compatible interface (mode 1) Applications:Temperature sensor measurement:1.Thermistor2.Thermocouple3.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
