ADS1226IRGVT General Description

The ADS1226IRGVT is a precision, low-power, 24-bit analog-to-digital converter (ADC) from Texas Instruments. It offers a high level of accuracy and resolution, making it suitable for applications requiring precise measurements such as industrial process control, sensor data acquisition, and medical instruments.Some key features of the ADS1226IRGVT include a programmable gain amplifier (PGA) with selectable gain settings from 1 to 128, allowing for flexibility in measuring a wide range of input signals. It has two differential input channels, enabling the user to perform simultaneous measurements or differential measurements for increased noise immunity.The device operates on a low power supply voltage range of 2.3V to 5.5V and consumes minimal power, making it ideal for battery-operated devices or applications where power efficiency is critical. It also features a built-in temperature sensor for accurate compensation of temperature drift.The ADS1226IRGVT communicates with a microcontroller through a standard serial peripheral interface (SPI), providing easy integration into various systems. It is housed in a 16-pin TSSOP package, offering a compact and space-saving solution for designs with limited board space.
