Analog-to-digital converters (ADC) are electronic circuits that convert analog signals, such as voltage and current, into digital signals. The ADC34J22IRGZT is a high-speed, monolithic CMOS-based dual-channel, 10-bit analog-to-digital converter which encodes analog voltage and current signals into 10-bit words. It features 1Msps operation, dynamic offset and gain correction, power consumption of 1.8 mA and up to a 10 MHz bandwidth.

Application Field

ADC34J22IRGZT is widely used in a variety of applications that require high-speed data acquisition and processing, including medical imaging, industrial process control, and automotive, to name a few. It is especially suitable for applications that need high input bandwidths, such as audio or video signal processing. The ADC34J22IRGZT offers a versatile 10-bit resolution that allows users to accurately acquire, measure, and convert a variety of input signals without sacrificing performance or price.

Working Principle

The ADC34J22IRGZT utilizes a delta-sigma converter architecture to convert analog signals into 10-bit digital words. It features a differential input stage, which helps reject common-mode noise and improve accuracy. The device samples and encodes incoming signals at a sampling rate of 1Msps (1 million samples per second), allowing for high throughput. It uses a dynamic offset and gain correction technique to further improve accuracy. The device features a power-down mode, allowing for a power-saving of up to 70%.

The ADC34J22IRGZT is a two-channel converter and can be used to convert two independent analog signals into 10-bit digital words. The two channels can be connected to two different analog signals or to the same signal, allowing for simultaneous sampling of the same signal. The device also offers three distinct output formats – two\'s complement, straight binary, and gray code – that can be selected via software programming.

The ADC34J22IRGZT features a wide input bandwidth of up to 10MHz, allowing for the direct conversion of high frequency signals. It also features a wide operating temperature range of -40°C to +125°C, making it well-suited for high-temperature applications such as automotive and aerospace.

The ADC34J22IRGZT is an ideal monolithic dual-channel 10-bit analog-to-digital converter that provides superior accuracy and high throughput. Its wide input bandwidth, low power consumption, wide operating temperature range, and three output formats make it a versatile and reliable solution for data acquisition applications.
