24-bit Sigma-Delta Analog-to-Digital Converter GX7793 - A Premium Alternative to the AD7793

In today‘s digital era, accurate data measurement has become an indispensable part of every industry. Whether in the field of healthcare, industrial control or environmental monitoring, high-precision data acquisition is the key to ensure stable system operation and improve efficiency. 24-bit sigma-delta analog-to-digital converters have become the new favorites in the field of precision measurements due to their excellent performance and flexible functions. The following mainly introduces two 24-bit Σ-Δ type analog-to-digital converter AD7793 and GX7793 performance characteristics and parameters can be realized to replace.

AD7793 Characteristics Introduction:

The AD7793 is a low-power, low-noise, complete analog front-end suitable for high-precision measurement applications. It has a built-in low-noise 16-bit/24-bit sigma-delta ADC containing three differential analog inputs, and also integrates an on-chip low-noise instrumentation amplifier, and thus allows for direct input of small signals. Root-mean-square (RMS) noise is 40nV at a gain setting of 64 and an update rate of 4.17Hz. A precision low-noise, low-drift internal bandgap reference is built-in, and an external differential reference can also be used. Other on-chip features include a programmable excitation current source, fuse current control, and a bias voltage generator. The bias voltage generator can be used to set the common mode voltage of a channel to AVDD/2.

GX7793 features are introduced:

1, high accuracy and low noise, GX7793 uses 24-bit Σ-Δ type ADC, providing a very high resolution makes it possible to detect very small signal changes, excellent low noise performance to ensure the accuracy and reliability of the measurement results.

2, a variety of input channel configuration, the GX7793 provides three differential input channels, to support a variety of sensors access, such as temperature sensors, pressure sensors and humidity sensors.

3, built-in high-performance reference voltage source and high-precision reference current source, can effectively save the system components and system circuit complexity.

4, low-power design, in order to ensure high performance at the same time GX7793 also pay special attention to the optimization of power consumption. It has extremely low power consumption in normal operation mode, and provides a variety of power management modes, including shutdown mode and standby mode, which can effectively extend the battery life of the device, especially suitable for portable devices or remote monitoring systems.

5. The GX7793 utilizes an SPI interface, which enables it to be easily connected to a variety of microprocessors or digital systems, making it more convenient in system design.

In summary, the GX7793 excels in performance parameters, functional characteristics, power supply and packaging, cost and availability, and application scenario compatibility. Moreover, with lower noise and power consumption, the GX7793 is an analog-to-digital converter that can be a good alternative to the AD7793, providing engineers with more choices and possibilities in the process of circuit design and optimization.
