Brief Product Description

The Microchip MCP3422A0-E/SN is an 18-bit dual-channel Delta-Sigma ADC engineered for high-precision data acquisition. Featuring differential inputs with programmable gain (1/2/4/8) and an on-chip 2.048V reference, it converts analog signals with minimal noise. The I²C interface supports selectable sampling rates (3.75–240 SPS) and both continuous/single-shot modes, enabling flexible operation and low-power standby. Housed in an 8-SOIC surface-mount package, it operates over 2.7V–5.5V and -40°C–125°C, making it ideal for industrial sensing, medical equipment, and harsh-environment systems requiring compact, robust design.
