Analog-to-Digital Converter GX1258 - ADS1258 High Quality Replacement Solution

The analog to digital converter GX1258 can be PIN TO PIN compatible with ADS1258 means that when designing circuits, engineers can easily make chip substitutions without having to make large-scale changes to the board layout and wiring. This not only saves R&D time, but also reduces design costs and risks.

1, resolution and accuracy

The ADS1258, a 24-bit Δ-Σ ADC, is known for its high accuracy, and the GX1258 also has a 24-bit resolution at the same level of accuracy as the ADS1258. Both provide accurate digital outputs for precision measurement applications such as industrial sensor signal acquisition and physiological signal measurement for medical devices. In terms of DC stability, the GX1258 and ADS1258 have a typical 0.02μV offset per degree Celsius and 0.4ppm gain offset per degree Celsius, which means that stable measurement accuracy can be maintained in temperature changing environments, reducing temperature-induced measurement errors.

2. Noise Characteristics

In terms of noise performance, ADS1258 and GX1258 in 1.8kSPS sampling rate, the noise is only 2.8μVrms, in the extremely sensitive to noise application scenarios, such as weak bioelectricity signal acquisition can provide a purer digital signal output, for the subsequent signal processing and analysis to provide a higher-quality data base.

3, sampling rate and power consumption

ADS1258 supports a variety of sampling rates to meet the needs of different applications, and GX1258 also provides flexible sampling rate options up to 30kSPS, which can be adapted to various types of signal acquisition scenarios. In terms of power consumption, the GX1258 adopts a unipolar +5V power supply with standby, sleep and shutdown modes, and power consumption is as low as 42mW, which significantly extends the life of the device and reduces energy consumption in portable devices, battery-powered systems, and other applications with stringent requirements on power consumption.

4. Cost and Availability

From the cost point of view, GX1258 in the assurance of performance, often with a more competitive price, can reduce production costs for the enterprise, improve the price-performance ratio of the product. Supply, GXSC chip supply chain stability and responsiveness, GX1258 in the supply cycle and supply more advantages.

In summary, whether it is the performance parameters, functional characteristics, or application scenarios fit, cost and supply, GX1258 have shown as ADS1258 ideal replacement chip performance, providing engineers with more options.
