## Description

A 4-channel, 18-bit delta-sigma analogue-to-digital converter (ADC) module based on the Microchip MCP3424. This module adds high-accuracy analogue input capability to Raspberry Pi, Arduino, and other microcontroller platforms over I2C. The onboard programmable gain amplifier (PGA) allows the module to measure very weak signals with high resolution, while self-calibration of offset and gain on every conversion ensures consistent accuracy without manual trimming. Key Features 18-Bit Resolution – Programmable at 12, 14, 16, or 18 bits 4 Differential Channels – Measure multiple analogue signals simultaneously Programmable Gain Amplifier – ×1, ×2, ×4, ×8 gain settings Self-Calibrating – Automatic offset and gain calibration per conversion I2C Interface – Simple two-wire connection to your microcontroller Two Conversion Modes – One-shot (low power) and continuous Low Standby Current – 300 nA at 5V Specifications Operating Voltage – 2.7–5.5V Standby Current – 300 nA (5V) Operating Temperature – -40°C to +125°C Voltage Reference – 2.048V ±0.05%, drift 15 PPM/°C PGA Gain – ×1, ×2, ×4, ×8 Differential Input Range – -2.048V/PGA to +2.048V/PGA Data Rate – 240, 60, 15, 3.75 SPS (corresponding to 12, 14, 16, 18-bit) Gain Error – 0.05% (PGA=1, 18-bit) Offset Error – 15 µV (PGA=1, 18-bit) Input Interface – 4 differential channels, 2.54 mm pin header Output Interface – I2C, 2.54 mm pin header Board Size – 27 × 16 mm (1.06 × 0.63″) Ideal For Temperature sensing with RTD, thermistors, and thermocouples Bridge sensing for pressure, strain, and force Weigh scales and load cells Battery fuel gauges Package Contents 1× MCP3424 18-Bit ADC Module Resources DFRobot Wiki Arduino Library Raspberry Pi Library Datasheet (PDF) Schematic (PDF)
