ADS1148IPWR Typical application Circuitry

ADS1148IPWR

Texas Instruments offers a highly integrated delta-sigma analog-to-digital converter (ADC) called the ADS1148IPWR. It's intended for the demands of high-precision measurements like those found in temperature sensor applications, pressure measurement, industrial process control, and more.

Here's a conceptual framework of an application circuit using the ADS1148IPWR:

1. Power Supply: The ADS1148IPWR works with a power supply voltage ranging from 2.7V to 5.25V. Ensure that power supply decoupling capacitors are placed close to the ADD and DVDD pins.

2. Analog Inputs: A low-noise programmable gain amplifier (PGA) is a feature of the gadget. Connect the desired analog input to the AINU and INN pins (differential input) or AIN0-AIN7 (single-ended inputs), depending on the required application.

3. Digital Interface: The ADS1148IPWR communicates using a straightforward serial interface that is compatible with SPI. This involves connecting the SCLK, DIN, and OUT/DRY pins to the appropriate counterpart pins on your microcontroller or digital system.

4. Voltage Reference: The ADS1148IPWR uses an internal 2.048V reference, but also allows an external reference. If you're using an external reference, it should be connected to the REF and REF pins.

5. Temperature Sensor: If you're planning on utilizing the built-in temperature sensor, the TEMP pin should be configured appropriately.

6. Reset: A reset pin (RESET) is also available, allowing a reset without cycling the power supply.

Please note that this is an overarching summary and might not cover all the possible intricacies and features of designing a circuit with the ADS1148IPWR. For a thorough understanding and design guide, always refer to the ADS1148IPWR datasheet and the latest resources from Texas Instruments.
