GX7793 against AD7793, the ideal solution for industrial automation field

The 24-bit sigma-delta analog-to-digital converter with its high-precision features has been widely used in the field of industrial automation, collecting various sensor signals to realize real-time monitoring and control of production processes.AD7793, as ADI‘s star product, has attracted much attention. With the rise of domestic chip technology, GX7793 with its excellent performance has become a powerful counterpart of AD7793. This article mainly analyzes the respective characteristics and application advantages of these two chips.

Comparison of performance parameters:

AD7793 for high-precision measurement applications for low-power, low-noise, complete analog front-end, built-in a low-noise 24-bit Σ - Δ-type analog-to-digital converter, which contains three differential analog inputs, but also integrated the on-chip low-noise instrumentation amplifiers, and thus can be directly into the small signal. 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 into the device, and an external differential reference can also be used. Other on-chip features include a programmable excitation current source, fuse current control, and bias voltage generator.

The GX7793 is a low-power, low-noise, 24-bit sigma-delta ADC for high-precision measurement applications, with three differential analog inputs and an integrated on-chip, low-noise instrumentation amplifier for direct small-signal inputs. The GX7793 operates from a 2.7V to 5.25V supply with typical power consumption of 360µA in a 16-pin TSSOP package.

Cost Comparison:

Cost is often a key decision factor for enterprises when purchasing chips on a large scale, and the AD7793, as an internationally recognized brand, is relatively expensive due to R&D costs, brand premiums, etc. The GX7793‘s cost-control features make it the most cost-effective solution. GX7793 in the cost control is more advantageous, under the premise of guaranteeing performance, its price is much lower than the AD7793, can effectively reduce the production cost of the product, improve market competitiveness.

Overall, GX7793 is comparable to AD7793 in terms of performance, and has more advantages in terms of cost and supply stability, which is a good choice to replace AD7793. GXSC can provide stable supply channels and professional technical support.
