ADS1220IPWR Typical application Circuitry

ADS1220IPWR

Texas Instruments ADS1220IPWR is a 24-bit, high-precision analog-to-digital converter (ADC). It has multiple features, including programmable gain and data rates.

Below are instructions to make accurate connections to the specific pins of ADS1220IPWR:

1. Power Supply: Apply a power supply voltage ranging from 2.3V to 5.5V to the VDD (pin 20) of ADS1220IPWR. Your circuit's ground should be connected to the GND pin (pin 10).

2. Input Signals: The differential analog input to the ADS1220IPWR should be connected to the AIN0 (pin 5) and AIN1 (pin 4). Connect the AIN1 pin to the ground and supply the input to the AIN0 pin for single-ended measurements.

3. Reference Voltage: The reference voltage can be applied to the REFP0 (pin 6) and REFN0 (pin 3) pins. This reference voltage denotes the full-scale input range.

4. Digital Interface: The ADS1220IPWR uses an SPI interface to connect with the host controller. Connect the controller's SPI bus to the SCLK (pin 14), DIN (pin 13), and OUT/DRY (pin 12) pins of ADS1220IPWR.

5. Data Ready and Start Conversion: The START (pin 11) pin is used to initiate conversions when the ADS1220IPWR is in a power-down state or when using sync mode. The OUT/DRY (pin 12) pin goes low when new data is ready to be shifted out.

6. Reset: The RESET pin (pin 19) can be used to reset the ADS1220IPWR. Apply a high signal momentarily to this pin to reset the device.

7. Decoupling Capacitors: It's recommended to connect decoupling capacitors close to the VDD and GND pins of the ADS1220IPWR to filter out any noise present in the power supply.

This guide provides a basic connection layout for the ADS1220IPWR. Depending on the particular requirements of your design, you might need to create more variants. For comprehensive and precise information, always refer to the most recent datasheet and reference manual.
