Applications
The MCP3562R-E/ST is ideal for precision industrial measurement applications such as weigh scales, pressure sensors, temperature transmitters, and gas analyzers that require 24-bit resolution at moderate sampling rates. Its integrated voltage reference and 4-channel input multiplexer simplify designs in portable scientific instruments and data acquisition modules where board space and component count are critical constraints. The device is also well suited for smart energy meters and battery management systems that measure millivolt-level signals across shunt resistors with low linearity error.

Frequently Asked Questions
What is the effective resolution and sampling rate of the MCP3562R-E/ST in a typical industrial sensor application?
The MCP3562R-E/ST delivers 24-bit resolution with a maximum sampling rate of 153.6 kSPS and a linearity error of no more than 0.0032%, making it suitable for precision industrial sensors such as strain gauges and pressure transducers. At lower oversampling ratios configured via SPI, it balances noise performance against throughput, allowing designers to trade speed for resolution depending on whether the application requires fast 16-bit scans or slow 24-bit precision measurements.
How does the integrated voltage reference in the MCP3562R-E/ST simplify precision measurement board design?
Including an on-chip voltage reference eliminates the need for an external precision reference IC, reducing the bill of materials by at least 1 component and the associated decoupling capacitors. The integrated reference in the MCP3562R-E/ST maintains stable output over the -40°C to 125°C temperature range, which is essential for industrial field instruments where ambient temperature swings would otherwise cause reference drift and shift the ADC's full-scale accuracy.
When does a precision weigh-scale or analytical instrument benefit most from using MCP3562R-E/ST over a 16-bit SAR ADC?
A 24-bit delta-sigma converter like the MCP3562R-E/ST is the better choice when the sensor signal occupies only a small fraction of the ADC's full-scale range, for example a 10 mV bridge output measured against a 3.3 V reference. In such scenarios a 16-bit SAR ADC provides only about 300 counts of useful resolution, while the MCP3562R-E/ST with 0.0032% linearity error resolves signal differences smaller than 1 µV, enabling sub-gram discrimination in precision scales or part-per-million concentration measurements in gas analyzers.
How many channels can be connected to the MCP3562R-E/ST simultaneously, and how are they selected?
The MCP3562R-E/ST provides 4 differential input channels or up to 8 single-ended inputs with an analog input range from -2.7 V to 3.6 V. Channel selection is performed through the SPI register interface, allowing the host microcontroller to multiplex measurements across temperature, pressure, and current-sense signals on a shared 20-pin TSSOP footprint without additional external multiplexer ICs.
