ADS1220IPW Typical application Circuitry

ADS1220IPW

Texas Instruments' ADS1220IPW is a high-precision, 24-bit, delta-sigma analog-to-digital converter (ADC), and it has several built-in capabilities that help sensor measurement applications save money and simplify their component lists. Here is a general outline on how to connect the ADS1220IPW in a typical application circuit:

1. Power Supply: The ADS1220IPW operates from a power supply ranging from 2.3V to 5.5V. Connect the power supply to the VDD pin.

2. Reference Voltage: This device uses an internal reference but also gives the option to use an external reference. If using an external reference, connect the voltage reference to the REFP and REFN pins.

3. Input Signal: Connect your sensor or input signal source to the AIN0 and AIN1 pins for differential measurements, or AIN0 to AIN3 for single-ended measurements.

4. Digital Interface: The device has an SPI-compatible serial interface for communication. Connect the SCLK, DIN, and DOUT/DRDY pins to your microcontroller or other digital device accordingly.

5. Reset: The device includes a power-on-reset circuit that initializes the device into a known state. Additional resetting can be done through the SPI interface.

6. Decoupling Capacitors: Connect decoupling capacitors close to the VDD and GND pins. These capacitors can filter out any noise or sudden changes in the voltage supply.

7. Ground: Connect all ground (GND) pins to your system ground.

For detailed instructions and information about recommended circuit components, power-up sequencing, analog input configuration, data rate selection, and calibration, etc., consult the ADS1220IPW datasheet. The datasheet will provide the specific guidance needed to use this ADC effectively in your design. To provide a full front-end solution for temperature sensor applications (including thermocouples, thermistors, and resistance temperature detectors (RTDs)), the ADS1220IPW also has a number of additional features, including a low-drift voltage reference, an oscillator, a PGA, and both high-side and low-side digital supplies.
