ADS1248IPWR Typical application Circuitry Schematics

ADS1248IPWR

The ADS1248IPWR is a precision, 24-bit, analog-to-digital converter (ADC) developed by Texas Instruments. It's typically used for applications like temperature measurement with thermocouples or Rods, pressure measurement, and other precise sensor measurements. Here's a basic overview for designing an application circuit with the ADS1248IPWR:

1. Power Supply: The ADS1248IPWR operates at a supply voltage of 2.7 to 5.25 V. You'll need to provide a stable power supply within this range. For noise-sensitive applications, linear voltage regulators are often used to provide power to the ADC.

2. Reference Voltage: This ADC requires a reference voltage that sets the scale for the conversion. This reference can be an external source, or it can use the internal reference of 2.048 V provided by the ADS1248IPWR.

3. Analog Input: Connect your sensor or signal source to the ADC's analog input pins. The ADS1248IPWR has differential input, which can help reduce noise and increase precision.

4. Decoupling Capacitors: It's a good practice to place decoupling capacitors close to the power supply pins to filter out any high-frequency noise. A 10uF capacitor in parallel with a 0.1uF ceramic capacitor is often used.

5. Digital Interface: The ADS1248IPWR uses an SPI (Serial Peripheral Interface) for communication with a microcontroller or other digital device. Connect the relevant SPI pins (DIN, OUT, SILK, and CS) to your microcontroller.

6. Temperature Sensor: If you're using the ADS1248IPWR for temperature measurement, connect your thermocouple or RTD to the analog inputs. You may also need additional circuitry for cold junction compensation and signal conditioning.

Remember, this is just a basic guide. Always refer to the ADS1248IPWR data sheet and application notes from Texas Instruments when designing your circuit. These resources will provide detailed information on pin configuration, electrical characteristics, and more. Also, for initial testing and configuration, consider using an evaluation module (EVM) if one is available.
