Key Features of the ADS1248IPWR

The ADS1248IPWR is a high-precision 24-bit analog-to-digital converter (ADC) with sophisticated capabilities that make it suitable for a wide range of sensor measurement applications. In this section, we will look at the important features that distinguish the ADS1248IPWR and make it a versatile choice for precise data acquisition:

● Programmable Data Rates and Single-Cycle Settling

The ADS1248IPWR supports data rates up to 2 kSPS (samples per second). This adaptability lets you tune the ADC’s performance to the precise needs of your sensor and measurement system. Additionally, the ADC’s single-cycle settling feature ensures that it immediately stabilizes after each conversion, allowing for speedy and effective data gathering.

● Noise Reduction and Rejection of Interference

The ADS1248IPWR reduces noise in analog signals by using a low-noise programmable gain amplifier (PGA) that can produce gains of up to 128 V/V. It also has a precise delta-sigma () ADC with a single-cycle settling digital filter, which is very successful in rejecting interference from common power line frequencies like 50 Hz and 60 Hz. This ensures that even in loud conditions, your measurements remain accurate.

● Analog Multiplexer and Input Options

The analog multiplexer of the ADC offers many input possibilities, making it adaptable to a wide range of sensor kinds and setups. The ADS1248IPWR has 8 independently configurable inputs, which is very helpful for applications that require numerous sensor inputs or sensor array configurations. This adaptability makes sensor integration into your measuring system easier.

● Programmable Gain Amplifier (PGA)

The integrated PGA, which has variable gains of up to 128 V/V, allows you to amplify weak sensor signals to a level appropriate for precise digitization. This functionality is critical for applications that use sensors that generate low-level signals because it ensures that you acquire and analyse the whole spectrum of sensor data without losing detail.

● Excitation Current Sources and Voltage Reference

The ADS1248IPWR goes a step further by including dual-matched programmable excitation current sources (IDACs) and an inbuilt 2.048-V reference with low drift. These characteristics are extremely useful for sensor measurement applications that require excitation currents or a constant voltage reference to power sensors such as resistive bridge sensors, thermocouples, and others.

● Sensor Burn-Out Detection

The ADC has sensor burn-out detection for enhanced reliability. This feature will notify you if a sensor fails or becomes detached, preventing incorrect measurements and enabling for early repair or replacement of malfunctioning sensors.

● General-Purpose I/Os and Monitoring

Depending on the model, the ADS1248IPWR has 4 or 8 general-purpose digital I/Os. These I/Os can be used to monitor the system, interface with external devices, or create custom control logic. This adaptability broadens the ADC’s utility beyond simple data gathering.

● Calibration and Serial Interface

The ADS1248IPWR enables personal and system calibration processes to achieve the best accuracy in your measurements. This compensates for any drift or offset in the performance of the ADC over time. In addition, the ADC has an SPITM-compatible serial interface, which simplifies connection with microcontrollers and digital systems.

The ADS1248IPWR has a plethora of capabilities that make it an excellent choice for precision sensor measurement applications. Its programmable data rates, noise reduction capabilities, analog multiplexing, and other integrated functions enable engineers and researchers to obtain accurate and reliable data from a wide range of sensors, enabling advancements in fields such as temperature sensing, industrial automation, and others.
