Analog to Digital Converters

MCP3422A4-E/SN Description

The MCP3422A4-E/SN 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. This single-channel ADC features differential inputs, an integrated programmable gain amplifier (PGA), and an I2C interface, making it ideal for space-constrained and power-sensitive designs. Operating over a 2.7V to 5.5V supply range, it supports both analog and digital voltage domains, ensuring compatibility with a wide range of microcontrollers and sensors. Packaged in an 8-SOIC tube, it is RoHS3 compliant and rated for MSL 1 (Unlimited), ensuring reliability in industrial and consumer applications.

MCP3422A4-E/SN Features

• 18-bit resolution for high-precision measurements.
• Differential input configuration reduces noise and improves accuracy.
• Integrated PGA with selectable gains (1x, 2x, 4x, 8x) for flexible signal conditioning.
• I2C interface enables easy integration with microcontrollers.
• Low power consumption, ideal for battery-operated devices.
• Wide supply range (2.7V–5.5V) supports mixed-voltage systems.
• Internal voltage reference eliminates the need for external components.
• 3.75 samples/second conversion rate balances speed and resolution.
• Surface-mount (SOIC-8) package optimizes board space.
