MCP3426A0-E/MS

MCP3426A0-E/MS Description

The MCP3426A0-E/MS from Microchip Technology is a high-precision, 16-bit delta-sigma analog-to-digital converter (ADC) designed for low-power, high-accuracy measurement applications. Housed in an 8-pin MSOP package, this ADC integrates a single-channel differential input with an I2C-compatible interface, making it ideal for space-constrained designs. Operating across a 2.7V to 5.5V supply range (analog and digital), it supports 15 samples per second (SPS) with an internal reference and programmable gain amplifier (PGA) for enhanced signal conditioning. Its differential input reduces noise susceptibility, while the ROHS3 compliance and REACH unaffected status ensure environmental and regulatory compatibility.
