1.
Product Characteristics Low current consumption: as low as 120 A (typical) in duty cycle mode
Power supply range: 3V~5 V Up to 20-bit effective resolution with two differential or four single-ended inputs
Dual matched programmable current sources: 10 µA to 1.5 mA
Internal 2.048 -V reference: 5 ppm/°C (typical) drift Internal 2% precision oscillator
Internal temperature sensor: 0.5 °C (typical) accuracy SPI compatible interface (mode 1)
2. Product Applications Temperature Sensor Measurement. W1G Electro7 YouXin Electroni! -Thermistor -Thermocouple Resistance
Temperature Detectors (RTD): 2, 3 or 4 wire type 2 wire bridge
Sensor Measurement: -Pressure Sensor -Pressure transducers -Strain Gauges -Scales Portable Instruments Factory automation and process control 3. Description The ADS1220 is a precision 24-bit analogue-to-digital converter (ADC) that provides a number of integrated features to reduce system cost and part counts for measuring small sensor signals. The device implements two differential or four single-ended inputs via a flexible input multiplexer (MUX), whisper, programmable gain amplifier (PGA), two programmable excitation current sources, a voltage reference, an oscillator, a low-side switch, and a precision temperature sensor. The device can convert at a data rate of 2000 samples per second (SPS) with single-cycle settling. At 20 SP, digital filters provide simultaneous 50 Hz and 60 Hz rejection for noisy industrial applications. The internal PGA provides hig...
