MCP3423T-E/UN

MCP3423T-E/UN Description

The MCP3423T-E/UN from Microchip Technology is a high-precision, low-power 18-bit delta-sigma analog-to-digital converter (ADC) designed for applications requiring accurate signal acquisition. Housed in a compact 10-MSOP package, it integrates a single ADC with two differential inputs, making it ideal for space-constrained designs. Operating from 2.7V to 5.5V (analog and digital supplies), it supports I2C communication and features an internal reference, eliminating the need for external components. With a 3.75 samples per second (SPS) sampling rate, it delivers high-resolution measurements for low-frequency signals while maintaining minimal power consumption.

MCP3423T-E/UN Features

• 18-bit resolution for ultra-precise analog signal conversion.
• Differential input configuration reduces noise and improves accuracy in noisy environments.
• Programmable Gain Amplifier (PGA) with selectable gains (1x, 2x, 4x, 8x) enhances sensitivity for low-voltage signals.
• I2C interface with selectable address pins enables easy integration into multi-device systems.
• Internal voltage reference ensures stable performance without external components.
• Low power consumption and 2.7V–5.5V supply range suit battery-powered and portable applications.
• RoHS3 compliant and REACH unaffected, meeting environmental regulations.
• Surface-mount (MSOP-10) package optimizes board space in compact designs.

MCP3423T-E/UN Applications

The MCP3423T-E/UN excels in precision measurement systems, including:

• Industrial sensors (strain gauges, thermocouples, pressure sensors).
• Portable medical devices (patient monitoring, glucose meters).
