7Semi MCP3421 18-Bit Analog-to-Digital Converter for Weighing Scales
The 7Semi MCP3421 18-Bit Analog-to-Digital Converter (ADC) is a high-precision solution for applications that require accurate analog signal measurement, especially weighing scales and weight measurement systems. With 18-bit resolution and differential inputs, it can capture small changes in sensor signals with good accuracy.
The built-in 2.048V voltage reference provides a stable reference for consistent measurements, while the programmable gain amplifier offers selectable gains of 1, 2, 4, or 8 to suit different input signal levels. The ADC communicates through the I²C interface, making it convenient to connect with microcontrollers and development boards.
With programmable sampling rates from 3.75 to 240 samples per second, the MCP3421 is well suited for digital weighing scales, precision sensor interfaces, load cell measurement, and other high-accuracy data acquisition applications.
Features:
- Even in the most demanding conditions, 18-bit resolution assures precise reading.
- 4 pin 2.0 mm pitch connector for easy integration.
- Ideal for use as a weigh scale, fuel gage, temperature sensor, and other applications.
- Supports differential inputs, which enable positive or negative measurements between two signals.
- Seamless connection with a clock rate of up to 3.4MHz ensures smooth data transfer.
- Built-in accuracy and low-drift reference voltage, as well as adjustable gain, allow for more flexible operation.
- While maintaining high precision, the MCP3421 allows you to modify the conversion speed to meet your individual requirements.
