Key Features
- 24-bit delta-sigma conversion with 0.0032% maximum integral non-linearity error for high-accuracy industrial measurement and process control
- 4 single-ended or 2 differential analog input channels on a single device reduce external multiplexer requirements in multi-sensor front ends
- Integrated precision voltage reference eliminates a separate reference IC, lowering BOM cost and simplifying PCB layout
- TSSOP-20 package at sub-25 mm² footprint fits dense analog acquisition boards alongside SPI microcontrollers and signal conditioning circuits
Applications
MCP3562RT-E/ST is used in precision industrial sensors, flow meters, and pressure transducers that require 24-bit resolution for detecting sub-millivolt signal changes from bridge transducers. Its wide analog input range of -2.7 V to 3.6 V and integrated voltage reference suit chemical analysis instruments, medical diagnostic equipment, and smart energy meters. The SPI interface and 4-channel multiplexed input make it straightforward to connect to a PIC or ARM microcontroller for multi-point environmental monitoring.

Frequently Asked Questions
What resolution and linearity does MCP3562RT-E/ST offer for a precision pressure-transducer readout?
MCP3562RT-E/ST provides 24-bit delta-sigma resolution with a maximum integral non-linearity error of 0.0032%, corresponding to roughly 2 LSB at 24 bits. For a 100 mbar full-scale pressure transducer producing a 10 mV bridge output, this linearity translates to sub-microvolt measurement uncertainty after gain, sufficient for calibration-grade industrial pressure logging.
How many input channels does MCP3562RT-E/ST support, and can they be used differentially?
MCP3562RT-E/ST includes 4 analog input channels that can be configured as 4 single-ended inputs or 2 fully differential pairs. The differential mode rejects common-mode noise from the analog input cable, which is critical in industrial environments with 50 Hz or 60 Hz EMI interference, and allows use of bipolar signals within the -2.7 V to 3.6 V absolute input range.
What advantage does the integrated voltage reference in MCP3562RT-E/ST provide over using an external reference IC?
Integrating the voltage reference eliminates one additional IC, its decoupling capacitors, and the PCB routing between a separate reference and the ADC's VREF pins. This reduces board area by approximately 10 mm² to 20 mm², lowers the BOM by 2 to 4 components, and avoids noise injection on the reference trace — a common accuracy bottleneck in high-resolution 24-bit ADC designs.
For a smart energy meter design, how does MCP3562RT-E/ST compare to a 16-bit SAR ADC in terms of dynamic range for current measurement?
A 24-bit ADC yields a theoretical dynamic range of 144 dB versus 96 dB for a 16-bit SAR, allowing simultaneous accurate measurement of standby loads below 1 mA and peak currents above 100 A on the same channel without range switching. This removes the need for a dual-range frontend circuit, simplifying the current transformer interface and reducing calibration complexity in Class 0.2 energy meters.
