Low Power CJMCU-1220 ADS1220 A/D Converter ADC SPI 24-Bit Og-to-Digital Converter Module For Arduino 3-5V

Selling Point

Product descrtion:The DS1220 is a precision 24-bit og-to-digital converter (ADC) that provides many integrated features to reduce system cost and component count for small r signals. The device paes a ible input multlexer (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 r 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 precitation. 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 r signals such as resistance temperature detectors (RTDs), thermocouples, thermistors, and resistive bridge rs. The device supports measurement of pseudo or fully differential signals when using the programmable gate array. Alternatively, the device can be configured to pa 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 leadle 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 (tyal)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 (tyal) DriftInternal 2% precision oscillatorInternal temperature r: 0.5°C (tyal) accuracySPI compatible interface (mode 1) Applications:Temperature r measurement:1.Thermistor2.Thermocouple3.
