MCP3426A0T-E/MS

MCP3426A0T-E/MS Description

The MCP3426A0T-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 internal reference and programmable gain amplifier (PGA), making it ideal for space-constrained designs. Operating from 2.7V to 5.5V (both analog and digital supplies), it supports I2C communication, enabling seamless integration into microcontroller-based systems. With a 15 SPS sampling rate, it balances resolution and speed for precision sensor interfacing.
