MCP3421A0T-E/CH - MICROCHIP
The MCP3421A0T-E/CH is a tiny 18-bit Delta-Sigma ADC with an I²C interface and internal PGA, ideal for precision measurement in severely space-constrained designs. Select this device when your application needs high-accuracy differential sensing with gains of 1, 2, 4, or 8—all in a SOT-23-6 package. Its 3.75 SPS output suits slow-changing signals like temperature sensors, pressure transducers, strain gauges, and battery voltage monitors. The internal 2.048V reference simplifies design. With -40°C to +125°C operation, it excels in industrial process transmitters, portable medical instruments, and HVAC sensors. The two-wire I²C interface minimizes connections, making it perfect for remote sensing nodes in factory automation and energy management systems.
