The ADS1112IDRCRG4 is a high-precision, low-power, 24-bit sigma-delta (ΣΔ) analog-to-digital converter (ADC). It is a part of Texas Instruments\' data acquisition product portfolio and can be used for weight cell applications, low-power temperature measurement, industrial process instrumentation and other real-time signal measurements. It offers superior performance in terms of its accuracy and its low power consumption.

This chip is capable of converting a range of +2.6V to +6V input voltage signals into digital words with a resolution of 24 bits. It features the industry-leading incremental signal-to-noise-and-distortion ratio (ISNR) of up to 110dB, and a full power-down mode. It has a built-in input buffer, a programmable digital filter and a low-power comparator. The integrated analog front end (AFE) supports a software programmable input signal timing, with a fast and data rate of 4 samples/sec. Its serial interface allows for easy connection to microcontrollers and other digital signal processing circuits.

The ADS1112IDRCRG4 is suitable for a broad range of applications - from industrial process control and chemical process analysis to precision temperature measurement and weight cell measurements. It can be used to measure temperature and humidity, pressure, strain and force, flow, and other physical parameters. With its impressive accuracy and low power consumption, it is the perfect choice for applications that require high-quality data acquisition and accurate measurement.

The ADS1112IDRCRG4 works on the principle of pulse density modulation (PDM). In PDM, an analog signal is converted into a series of pulses whose density varies in accordance with the instantaneous value of the input signal. This is achieved by modulating the duty cycle of the pulses in the signal.

The output from the ADC is a digital word representative of the analog input value. The resolution of the output is decided by the number of bits in the output word. With a resolution of 24 bits, the ADS1112IDRCRG4 offers a resolution of 1/16,384 - meaning that the actual analog value is reconstructed with unprecedented accuracy.

In addition to its high resolution, the ADS1112IDRCRG4 also offers a low voltage operation down to +2.6V and a flexible serial interface. An on-chip oscillator eliminates the need for external crystal clock components, thereby reducing cost and space requirements. The chip also supports a software programmable input signal timing, providing designers with more flexibility.

The ADS1112IDRCRG4 is an ideal solution for applications that require high accuracy and low power consumption. It is particularly well-suited for temperature, pressure and force measurements, weight cell measurements, industrial process control and chemical process analysis. With its impressive performance and low cost, it is the perfect choice for a wide range of data acquisition applications.
