In the field of precision measurement, market competition is increasingly fierce, making the selection of
suitable ADC chips a challenge: they need to have high precision, high integration, low power consumption,
and high cost-effectiveness. The SGM58201, with its self-developed IP and innovative architecture design,
provides engineers with an ideal choice that balances performance and application needs.
The SGM58201, launched by Shengbang Microelectronics, is a new generation of high-performance 24-bit Σ-
Δ ADC, supporting 4 channels, with built-in PGA, MUX, REF, IDAC, and other functions. It boasts the highest
effective resolution of 22Bits ENOB, a temperature drift coefficient of 10ppm/°C over the full temperature
range, and a matching accuracy of the constant current source of 1/5000, setting a new benchmark for similar
products in the industry.
22Bits ENOB: Accurate Restoration of True Signals
In high-precision data acquisition applications, the actual effective resolution (ENOB) directly affects the
quality of the available data. The SGM58201 provides the highest 22Bits ENOB, ensuring users obtain true
and high-precision measurement data.
10ppm/°C Full-Temperature Drift: Accurate Measurement in Extreme Environments
Temperature drift is a significant concern in high-precision measurement systems, as temperature changes
can lead to a decrease in ADC measurement accuracy. The SGM58201 has a full-temperature drift
coefficient of only 10ppm/°C, ensuring excellent consistency of measurement data even within a wide
temperature range (-40°C to +125°C).
0.02% Constant Current Source Matching Accuracy: Precision RTD Sensing Measurement Tool
In applications such as RTD temperature measurement, the accuracy of constant current source matching
directly determines measurement accuracy. The SGM58201 boasts a constant current source matching
accuracy of up to 0.02% (0.02%), reducing the need for secondary sampling in traditional solutions and
significantly lowering calibration costs. Additionally, combined with single-cycle stabilization technology, it
achieves millisecond-level response times, meeting the inspection needs of high-speed production lines.
Evaluation Board (EVB)
To help customers quickly evaluate SGM58201, the product line support team at Shengbang
Microelectronics has developed a complete and stable EVAL board and GUI software package. This kit
supports real-time configuration of all registers and can calculate and display various data in the time
domain, frequency domain, and histograms in real time.
Reference Design Demo Board
For typical temperature transmitter applications of SGM58201, the AE team of Shengbang Microelectronics
has built a complete set of 4mA-20mA loop-powered reference circuit designs based on the company's
ADC, DAC, OPA, REF, and other core components, supporting functions such as TC and RTD, which
facilitates customers to evaluate the overall system's comprehensive performance indicators. Additionally,
the accompanying dedicated GUI can be used for detailed testing of the ADC and DAC, simplifying the
customer's evaluation work.
