ADS1220IRVAR Typical application Circuitry

ADS1220IRVAR

Texas Instruments produces the 24-bit ADS1220IRVAR analog-to-digital converter (ADC). It is commonly used in high-precision applications such as temperature sensor reading, gas monitoring, and industrial process control.

Let's delve into a typical application circuit for the ADS1220IRVAR, emphasizing four distinctive aspects:

1. Power Supply: The ADS1220IRVAR operates from a power supply voltage of 2.3V to 5.5V. The supply voltage is provided to the VDD pin. It is important to decouple the VDD pin to GND close to the ADC using a 10μF capacitor in parallel with a 0.1μF capacitor to filter out noise.

2. Input Signals: The ADS1220IRVAR has differential input, meaning it measures the voltage difference between the AINU (Analog Input Positive) and INN (Analog Input Negative) pins. These pins should be driven with a low-impedance source to avoid noise coupling.

3. Reference Voltage: The ADS1220IRVAR uses an external voltage reference. This reference voltage can be set between 1.25V and the supply voltage. The voltage reference is connected to the REF pin and decoupled to GND.

4. Digital Interface: The ADS1220IRVAR uses an SPI-compatible interface. This requires connections for SCLK (Serial Clock), DIN (Data Input), OUT/DRY (Data Output/Data Ready), and CS (Chip Select). The DRY pin goes low when new data is ready for retrieval.

5. Decoupling Capacitors: Place a decoupling capacitor close to the power supply pin and a bypass capacitor on the REF pin to reduce noise. Good layout practice is essential to ensure accuracy.

6. Thermal Management: As with any integrated circuit, thermal management is important. Ensure that the layout of the PCB allows for sufficient heat dissipation.

Please keep in mind that the final circuit design will be influenced by the details of your application. Always refer to the ADS1220IRVAR datasheet and relevant application notes provided by Texas Instruments for detailed design considerations.
